\chapter{General Information}
\setcounter{page}{1}
This chapter describes the RF71 integrated storage element\Index{Integrated storage element} (ISE) and the
enclosures into which it can be installed.

All installations should be documented using LARS. The correct system
name, option name, and serial numbers should be recorded for proper
installation tracking.

\section{RF71 ISE Overview}

The RF71 ISE (\figref{1-1}) is a full-height, 5-1/4-inch fixed disk mass
storage device. It is one of a family of storage devices based on the Digital
storage architecture (DSA) utilizing the DSSI bus and interface. The term
integrated storage element (ISE) refers to the fact that the RF71 has
embedded within it an intelligent controller and Mass Storage Control
Protocol (MSCP) server.

DSSI devices support up to seven ISEs daisy chained through a single
cable to an adapter in the host. DSSI adapters\Index{DSSI adapters} can be adapters embedded
within a CPU module (for example the KA640 module) or non-embedded
modules, such as the KFQSA adapter.

\fig{RF71-ISE-IMAGE}{The RF71 Integrated Storage Element}

\section{The BA213 Enclosure}

The BA213\Index{BA213} enclosure (\figref{1-2}) has a mass storage bay above the card
cage that contains either a TK70 tape drive or a TK50 tape drive, and up
to three DSSI ISEs.

Mass storage devices are mounted sideways on shock-mounting hardware
with a sliding track attached to each side of the device. One shock-resistant 
support attaches to the top of the mass storage, and
the other support attaches to the bottom of the device. The supports
are attached by two screws enclosed in rubber shock bushings. The
shock-mounting hardware is different for each ISE model that can be
installed.
\fig[0.7]{RF71-BA213-IMAGE}{The BA213 Enclosure}

\newpage

\section{The BA215 Enclosure}
EK-RF71D-IM-001.tex
The BA215\Index{BA215} enclosure (\figref{1-3}) has a mass storage bay that extends
across the top of the enclosure. It contains a TK70 tape drive or TK50
tape drive, and either one or two ISEs.

Mass storage devices are mounted sideways on shock-mounting hardware,
with a sliding track attached to each side of the device. One shock-resilient
support attaches to the top of the mass storage area, and the other support 
attaches to the bottom of the device. The supports are attached by two screws
enclosed in rubber shock bushings. The shock-mounting hardware is different
for each ISE model that can be installed.

\fig{RF71-BA215-IMAGE}{The BA215 Enclosure}
\newpage

\section{The R215F Enclosure}

The R215F\Index{R215F enclosure} enclosure is a BA215 enclosure with the card cage removed
and an additional mass storage bay. It has three mass storage bays: two
bays in the top of the cabinet, and a third bay in the misdle of the cabinet.
Each mass storage bay can hold one 13.3 cm (5.25-inch) ISE. \figref{1-4} is
a typical RF215 configuration that includes an RF215F expansion enclosure
and a MicroVAX 3400 in a BA213 enclosure.

Mass storage devices are mounted sideways on shock-mounting hardware
with a sliding track attached to each side of the device. One shock-resistant
support attaches to the top of the mass storage are, and the other support
attaches to the bottom of the device. The uspports are attached by two screws
enclosed in rubber shock bushings. The shock-mounting hardware is different
for each ISE model installed.

\chapter{Unpacking Information}
\setcounter{page}{1}

Unpacking the RF71 ISE consists of removing it from the shipping
container and inspecting for damage. Report any damage to the shipper
and notify your Digital representative.

\section{Unpacking Instructions}
\begin{enumerate}
\item Before opening any container, check for external damage such as
dents, holes, or crushed corners.
\item Open and unpack the shipping container. Remove the ISE from the
conductive plastic bag.
\end{enumerate}


\caution{When handling the RF71 ISE, observe all precautions to be sure
that you do not damage the device by accidental electrostatic
discharge.}

\note{Shipping containers and packing materials should be retained for
possible future use.}

\figref{2-1} illustrates all the parts included in the RF71E-SF Option Kit.

\chapter{Controls and Indicators}
\setcounter{page}{1}

This chapter describes the controls and indicators for the RF71 ISE.

\section{RF71 ISE Switches and LEDs}

\figref{3-1} shows the location of the switches and LEDs on the RF71 ISE.

\fig[0.8]{RF71-SWITCHES}{RF71 ISE Switch and LED Locations}
\newpage
\subsection{DSSI Node ID Select Switches}

The RF71 ISE had a DIP switchpack located next to the DSSI connector
that is used to assign a DSSI node ID number\Index{DSSI node ID number} to the ISE. Each device on
the DSSI bus must be assigned a unique node IDE between zero and seven.

Assignment of the DSSI node ID is made during installation by setting
the 3-position DIP switch to the binary equivalent of the desired ID
number (see \tabref{3-1}).

\begin{tbl}{DSSI Node ID Selection}{c l l l}
\textbf{DSSI Node} & \multicolumn{3}{l}{\textbf{Switch Positions\textsuperscript{1}}} \\
\textbf{Address} & \textbf{Switch 1} & \textbf{Switch 2} & \textbf{Switch 3} \\
\hline
0 & Down & Down & Down \\
1 & Down & Down & Up \\
2 & Down & Up & Down \\
3 & Down & Up & Up \\
4 & Up & Down & Down \\
5 & Up & Down & Up \\
6 & Up & Up & Down \\
7\textsuperscript{2} & Up & Up & Up \\
\hline
\multicolumn{4}{l}{\textsuperscript{1}Up is toward the HDA, down is toward the module.}\\
\multicolumn{4}{l}{\textsuperscript{2}Normally assigned to a host node.}\\
\end{tbl}

\note{These switches are ignored by the RF71 ISE when it is connected to an operator control
panel. In this case, use the OCP controls described in \hyperlink{section.3.9}{Section 3.9} 
to select the DSSI node ID.}

\subsection{READY Indicator}

This indicator is a green LED. When the ISE is powered up, this indicator is turned on. After successful
completion of the power-on self-test (POST), the indicator is turned off until the ISE is read/write ready.
\newpage
The READY LED is turned off during a seek until the drive heads are on a cylinder
and read/write ready. Then the indicator is turned on again for as long as the heads remain
on track. Thus, during read or write operations, the indicator flickers on and off rapidly.

\subsection{FAULT Indicator}
\Index{FAULT indicator}

This indicator is a red LED. It is turned on when a read/write error or serious physical
error condition is detected. Initially, when the ISE is powered up, this indicator
is turned on. Upon successful completion of POST, this indicator is turned off.

\section{Operator Control Panel (OCP)}
\Index{Operator control panel}
When the RF71 ISE is installed in a BA213, BA215 or R215F enclosure,
the operator interfave is a control panel on the enclosure. \figref{3-2}
shows the OCP. Its functions are described in \tabref{3-2}. Each RF-series
ISE is connected to the OCP through a 10-conductor ribbon cable.

The OCP has three columns of controls and indicators. The standard convention is 
to use the right column for ISE 0, the center column for ISE 1, and the left column
for ISE 2. Note, howeverm that the DSSI node IDE address is determined by the drive
select plug rather than its position on the OCP. The address that will be assigned to 
the ISE is labeled on the plug.

\note{The DSSI address assigned by the plug is read only during the power-up sequence. If
you change the plugs without reinitialising the ISE by a power-up or reset, the new DSSI
address is not recognised.}

\caution{Do not install two plugs with the same number on the OCP.}

\chapter{Verification}
\setcounter{page}{1}

This chapter explains how to verify the correct operation of the ISE once it is installed.

\section{Verifying the Correct Operation of an ISE}

\begin{enumerate}
\item	Check all cable connections to the device. Make sure all connectors
		are seated properly and that there is an appropriate amount of slack
		in the DSSI cable to allow for vibration of the ISE.

\item	Replace all panels on the enclosure.

\item	Make sure the DSSI cable is properly connected to both host and
		expansion box (if applicable).

\item	Apply power to the host and to the expansion box (if applicable). The
		RF71 ISE goes through the power-on self-test (POST) described in
		\hyperlink{chapter.6}{Chapter 6}. Make sure the green LED in the
		center of the READY button on the OCP comes on for that ISE. If the red
		FAULT LED comes on, test the ISE.
\newpage
\item	Once the READY LED lights, access the local program DRVTST using
		the following procedure:

\begin{enumerate}
	\item	For a MicroVAX running VMS Version 5.0 or later, type the
			following command:

			\texttt{\$ SET HOST/DUP/SERVER-MSCP\$DUP/TASK-DRVTST node-name}

			where:

			node-name = the node name of the device

			Add the qualifier /log=filename.exe to produce a file in your
			directory of what appears on the screen.
				
			To learn the node name of the device, type either SHOW DEVICES
			or SHOW CLUSTER at the \$ prompt.

	\item	For a MicroVAX using a KA640 module with an embedded DSSI
			adapter, use the following console command:

			\texttt{{>}{>}{>} SET HOST/DUP/DSSI \#}

			where:

			\# is the DSSI node address of the device you want to access.

			\texttt{{>}{>}{>} SHOW DSSI}

	\end{enumerate}
\end{enumerate}	


\note{To abort or prematurely terminate the program and return
control to the system, press \keystroke{CTRL/C} or \keystroke{CTRL/Y}.}

\chapter{Diagnostics}
\setcounter{page}{1}

This chapter describes the diagnostics available for verifying the operation
of the RF71 ISE.

\section{Power-On Self-Test (POST)}

All DSSI devices run a power-on self-test (POST)\Index{Power-on self-test (POST)} at power-up or when
the device is reset to check the integrity of the device hardware. POST
has two functions: it performs a sequence of tests to check that the ISE
hardware is functioning properly, and it performs start-up procedures to
make the ISE operational before becoming available to the host.

POST is executed whenever power is applied. If it is executed successfully,
the green READY indicator\Index{READY indicator} lights and the red FAULT indicator goes out.
If POST fails, the red FAULT indicator remains lit and the READY
indicator does not come on, or both indicators remain on.

When POST is initialised, it first activates the spindle spin-up sequence.
Spindle spin-up is started first because of the time required for the
spindle to come up to speed. Other tests are performed while the spindle
is spinning up. When there is more than one ISE on the system, spindle
spin-up is staggered to limit the starting current drawn from the power
supply for this function. The system controls the staggering through the
ACOK\Index{ACOK} signal.

POST is also used to handle the following types of error conditions:

\begin{enumerate}
\item	\textit{Controller errors} - These are error caused by the hardware
		associated with the controller function of the drive module.
		These errors are fatal to the operation of the ISE, since the
		controller can't establish a logical connection to the host.
		The result of a failure due to controller error is that the
		red FAULT LED lights.
\newpage
\item	\textit{Device errors} - These are errors caused by the hardware
		associated with the device control function of the drive
		module. These errors are not fatal, since the ISE can establish
		a logical connection and report the error to the host. The
		result of failure due to an ISE error is that both LEDs
		go out for about one second, then the red FAULT LED lights.
		In this case, run either DRVTST, DRVEXR, or PARAMS (as
		explained in the next section) to determine the error code.
\end{enumerate}

\section{Device Resident Diagnostics}

The RF71 ISE uses the following local programs to run device diagnostics.
These programs use the Diagnostic Utility Protocol (DUP) standard
dialog.

\begin{itemize}
\item	\textit{DIRECT} - provides the directory of available local programs
\item	\textit{DRVTST} - verifies that the hardware is functioning properly
\item	\textit{DRVEXR} - exercises the RF30 ISE
\item	\textit{HISTRY} - displays information retained by the ISE
\item	\textit{ERASE} - erases all user data from the ISE
\end{itemize}

A description of each diagnostic local program follows, including a table
showing the dialogue of each program. The table also indicates the type
of messages contained in the dialogue, although the screen display does
not indicate the message type. Message types are abbreviated as

\begin{itemize}
\item	\textit{Q} - question
\item	\textit{I} - information
\item	\textit{T} - termination
\item	\textit{FE} - fatal error
\end{itemize}

Local programs can be accessed by using console commands (for MicroVAX
3000-series systems) or the MDM utility, or through VMS using the SET
HOST/DUP command. Once the connection is established, operations are
performed under the control of the local program. When the program
terminates, control is returned to the system.
\newpage
\subsection{DIRECT}

DIRECT\Index{DIRECT} provides a directory of all available local programs resident in
the RF71 ISE. An example of a DIRECT program display is:

\begin{ttfig*}
	Copyright © 1988 Digital Equipment Corporation
	DIRECT    V1.0   D   1-NOV-1988    13:39:09

	End of Directory
\end{ttfig*}

\subsection{DRVTST}

DRVTST\Index{DRVTST} invokes a comprehensive test of the RF71 ISE hardware. Errors
detected by this program are isolated to the FRU level. Dialogue for this
test includes:

\begin{tbl}{}{p{1cm} l}
\textbf{Message Type} & \textbf{Message} \\
\hline
I & Copyright \copy 1988 Digital Equipment Corporation \\
Q & Write/read anywhere on the medium? [1=yes/(0=no)] \\
Q & User data will be corrupted. Proceed? [1=yes/(0=no)] \\
I & 5 minutes to complete. \\
T & Test passed. \\
\multicolumn{2}{c}{or} \\
FE & Unit is currently in use. \textsuperscript{1} \\
FE & Operation aborted by user. \\
FE & xxxx - Unit diagnostics failed. \textsuperscript{2} \\
FE & xxxx - Unit read/write test failed. \textsuperscript{2} \\
\hline 
\multicolumn{2}{p{10cm}}{\footnotesize \textsuperscript{1}This can mean either
the device is inoperative, is in use by a host, or is currently running
another local program.} \\
\multicolumn{2}{p{10cm}}{\footnotesize \textsuperscript{2}For the available
error codes, refer to the diagnostic error code table at the end of this
chapter.} \\
\end{tbl}

Answering no to the first question results in a read-only test, and
DRVTST writes are limited to a diagnostic area on the disk. Answering
yes to the first question results in the second question being asked.
\newpage
Answering no to the second question has the same effect as answering no
to the first question. Answering yes to the second question permits write
and read operations anywhere on the medium.

\note{If the WRITE PROTECT switch on the OCP is pressed in (LED on)
and the answer to the second question is yes, the device does not 
allow the test to run. The error message ``2006 - Unit read/write
test failed'' is displayed. In this case, the test has not failed, but
has been prevented from running.}

DRVTST resets the ECC error counters and then calls the timed I/O
routine. After the timed I/O routine completes (five minutes), DRVTST
saves the counters again. It computes the uncorrectable error rate and
byte (symbol) error rate. If either rate is too high, the test fails and the
appropriate error code is displayed.

\subsection{DRVEXR}

The DRVEXR\Index{DRVEXR} local program exercises the RF71 ISE. The test is data
transfer intensive and indicates the overall integrity of the device. The
dialogue for DRVEXR includes:

\begin{tbl}{}{p{1cm} l}
\textbf{Message Type} & \textbf{Message} \\
\hline
I & Copyright \copy 1988 Digital Equipment Corporation \\
Q & Write/read anywhere on the medium? [1=yes/(0=no)] \\
Q & User data will be corrupted. Proceed? [1=yes/(0=no)] \\
Q & Test time in minutes? [(10)-100] \\
I & ddd minutes to complete. \\
I & dddddddd blocks (512 bytes) transferred. \\
I & dddddddd bytes in error (soft). \\
I & dddddddd uncorrectable ECC errors (recoverable). \\
T & Complete \\
\multicolumn{2}{c}{or} \\
FE & Unit is currently in use.\textsuperscript{1}\\
\end{tbl}

{\footnotesize \textsuperscript{1}This can mean either the device is inoperative, is in use by a host, or is currently running another local program.}

\newpage


\begin{tbl}{}{p{1cm} l}
\textbf{Message Type} & \textbf{Message} \\
\hline
FE & Operation aborted by user. \\
FE & xxxx - Unit diagnostics failed.\textsuperscript{2}\\
FE & xxxx - Unit read/write test failed.\textsuperscript{2}\\
\hline
\multicolumn{2}{p{10cm}}{\textsuperscript{2}For the available error codes, refer to the diagnostic error code table at the end of this chapter.}\\
\end{tbl}

Answering no to the first question results in a read-only test, and
DRVEXR writes are limited to a diagnostic area on the disk. Answering
yes to the first question results in the second question being asked.

Answering no to the second question has the same effect as answering no
to the first question. Answering yes to the second question permits write
and read operations anywhere on the medium.

\note{If the WRITE PROTECT switch on the OCP is pressed in (LED on)
and the answer to the second question is yes, the device does not
allow the test to run. The error message ``2008 - Unit read/write
test failed'' is displayed. In this case, the test has not failed, but
has been prevented from running.}
 
DRVEXR saves the error counters and then calls the timed I/O routine.
After the timed I/O routine completes, DRVEXR saves the counters again.
It then reports the total number of blocks transferred, bytes in error, and
uncorrectable errors.


DRVEXR uses the same timed I/O routine as DRVTST with two
exceptions. First, DRVTST always uses a fixed time of five minutes, while
DRVEXR varies the time of the routine as the user specifies. Second,
DRVTST determines whether the device is good or bad. DRVEXR simply
reports the data without making any judgements about the condition of
the device.

\newpage

\subsection{HISTRY}

This local program displays information about the history of the RF71
ISE. The output generated by HISTRY\Index{HISTRY} consists of the following:

\begin{tbl}{}{p{1cm} l l}
\textbf{Message Type} & \textbf{Field Length\textsuperscript{1}} & \textbf{Field Meaning} \\

\end{tbl}
\newpage
The following is an example of what appears on the screen when HISTRY
is running:

\begin{verbatim}

    Complete.
\end{verbatim}
If no errors have been logged, no hexadecimal fault codes are displayed.

\newpage

\subsection{ERASE}

The ERASE\Index{ERASE} local program is used to overwrite application data on the
device disks while leaving the replacement control table (RCT)\Index{Replacement control table (RCT)} intact.
This local program is used in the event that a mechanics set must be
replaced and the customer wants to protect confidential or sensitive data.

ERASE should be used only in the event that the mechanics set must be
replaced and only after you have backed up the customer's data.

The dialogue for this program is as follows:

\begin{tbl}{}{p{1cm} l}
\textbf{Message Type} & \textbf{Message} \\
\hline
I	&	Copyright \copy 1988 Digital Equipment Corporation \\
Q	&	Write/read anywhere on the medium? [1=yes/(0=no)] \\

\multicolumn{2}{c}{or} \\
FE	&	Unit is currently in use. \\
FE	&	Operation aborted by user. \\

FE	&	xxxx - Operation failed. \textsuperscript{2} \\
\hline
\multicolumn{2}{p{10cm}}{\footnotesize\textsuperscript{1}For the available error codes, refer to the diagnostic error code table at the end of this chapter.} \\
\multicolumn{2}{p{10cm}}{\footnotesize\textsuperscript{2}xxxx = one of the following error codes:
\begin{itemize}
\item	000D : cannot write the RCT
\item	000E : cannot read the RCT
\item	000F : cannot find an RBN to revector to
\item	0010 : the RAM copy of the bad block table is full

\end{itemize}
}\\
\end{tbl}

\note{If the WRITE PROTECT switch on the OCP is pressed in (LED
on) and the answer to the second question is yes, the device does
not allow the test to run. The error message ``Operation aborted
by user'' is displayed. In this case, the test has not failed, but has
been prevented from running.}

If a failure is detected, the message indicating the fa;lure is followed by
one or more messages containing error codes.

\newpage

\section{Diagnostic Error Codes}
The diagnostic error codes\Index{Error codes} are displayed when running either DRVTST,
DRVEXR, or PARAMS. The following table lists the error codes that may
be displayed when running these local programs.

\chapter{The PARAMS Utility}
\setcounter{page}{1}
PARAMS is a local program that allows you to examine and edit internal
ISE parameters.

\section{Invoking PARAMS}

PARAMS is invoked in the same way as the local programs discussed in
the previous chapter. Once invoked, all interaction is through the use
of commands and responses. Valid PARAMS commands\Index{PARAMS commands} are listed in
\tabref{7-1}.

\begin{tbl}{Valid PARAMS Commands}{l p{7cm}}
\textbf{Command} & \textbf{Definition} \\
\hline
HELP		&	Shows all PARAMS commands and their syntax \\
SET			&	Sets a parameter to a value \\
SHOW		&	Displays a parameter or a class of parameters \\
STATUS		&	Displays module configuration, history, or current counters,
				depending on the status type chosen \\
WRITE		&	Records the device parameters you changed using the SET
				command \\
EXIT		&	Terminates the PARAMS local program \\
\end{tbl}

\newpage
\section{HELP}
The HELP\Index{HELP} command causes a brief list of available PARAMS commands
to be displayed. The following is an example of what appears on the
screen when you use the HELP command.
\begin{verbatim}
PARAMS> help
  EXIT
  HELP
  SET {parameter | .} value
  SHOW {parameter | . | /class}
    /ALL     /CONST   /DRIVE
    /SERVO   /SCS     /MSCP
    /DUP
  STATUS [type]
    CONFIG   LOGS     DATALINK
    PATHS    
  WRITE 

PARAMS>
\end{verbatim}

\section{SET}
The SET\Index{SET} command is used to edit internal ISE parameters. Syntax for
the SET command is:

\begin{quote}
    SET \textit{parameter} \textit{value}
\end{quote}

Where \textit{parameter} is the name of the parameter to be set, 
and \textit{value} is the value you want assigned to the parameter. 
If abbreviated, the first matching parameter is used without regard 
to uniqueness.

The WRITE command must be used to record the edits made while using
the SET command. SET parameters that are available to the user are
listed in \tabref{7-2}.

Examples:

\begin{verbatim}
    PARAMS> SET NODENAME SUSAN
\end{verbatim}
 
This sets the node name of the ISE to SUSAN.
\newpage

\begin{verbatim}
    PARAMS> SET FORCENAM 1
\end{verbatim}

This sets the node name of an RF71 with a DSSI node ID of 0 to RF30A.

\begin{tbl}{Summary of SET and SHOW User Parameters}{l l p{8cm}}
\textbf{Parameter} & \textbf{Class} & \textbf{Definition} \\
\hline
VOLSERNO	&	DRIVE	&	Shows the volume serial number as a quadword. \\
ALLCLASS	&	MSCP	&	Sets or shows the controller allocation class. The
							allocation class should be set to match that of the host.\\
UNITNUM		&	MSCP	&	Sets or shows the MSCP unit number.\\
FORCEUNI	&	MSCP	&	Determines whether the MSCP unit number or the
							DSSI node ID will be used. If the FORCEUNI value is
							0, the UNITNUM value will be used. If the FORCEUNI
							value is 1, the DSSI node ID will be used. \\
FIVEDIME	&	MSCP	&	Determines credit connections. If set to 1, MSCP will
							support five connections with ten credits each. If set
							to 0, MSCP will support seven connections with seven
							credits each. \\
CNT\_TMO		&	MSCP	&	Shows the MSCP controller timeout value.\\
ADD\_CR		&	DUP		&	Determines if DUP will append a RETURN character
							after each message. True if set to 1, false if set to 0.\\
ADD\_LF		&	DUP		&	Determines if DUP will append a LINEFEED character
							after each message. True if set to 1, false if set to 0.\\
SYSTEMID	&	SCS		&	Sets or shows the controller's 48-bit SCS system ID.\\
NODENAME	&	SCS		&	Sets or shows the SCS node name for the ISE.\\
FORCENAM	&	SCS		&	Determines whether the value set by the NODENAME
							command will be used or not. If the FORCENAM
							value is 1, the SCS node name should be forced to the
							string RF30x or RF71x, where x is a letter from A to
							H corresponding to the DSSI bus ID (for example, A=0,
							B=1, and so on) If the FORCENAM value is 0, the value
							set by NODENAME is used.\\
\end{tbl}
\newpage
\section{SHOW}

The SHOW\Index{SHOW} command displays the settings of a parameter or a class of
parameters. The full name of the parameter (8 characters or less), the
current value, the default value, radix and type, and any flags associated
with each parameter are displayed.

Syntax for the SHOW command is:

\begin{quote}
SHOW \textit{parameter\_or\_class}
\end{quote}

Where \textit{parameter\_or\_class} is either a parameter name or a class name.
If an abbreviation is used, the first matching parameter is displayed,
regardless of uniqueness. The parameter name may also be the special
character ``.'', which will display the last known parameter. If there is no
previous parameter, an error is given.

If a class name is used, the class name must be prefixed with a slash (/).
SHOW parameters that are available to the user are listed in tabref{7-2}.

Example:

\begin{verbatim}
PARAMS> SHOW ADD_CR
Parameter     Current          Default        Type    Radix
--------  ---------------  ---------------   -------  -----
ADD_CR                  0                0   Boolean   0/1
PARAMS> SET ADD_CR 1
PARAMS> SHOW ADD_CR
Parameter     Current          Default        Type    Radix
--------  ---------------  ---------------   -------  -----
ADD_CR                  1                0   Boolean   0/1
PARAMS>
\end{verbatim}

\newpage

\section{STATUS}

The STATUS\Index{STATUS} command can display module configuration, history, or
current counters. The syntax for the STATUS command is:

\begin{quote}
STATUS [\textit{type}]
\end{quote}

Where \textit{type} is an option that denotes the type of display desired. If
omitted, all available status information is displayed. If present, it may
be abbreviated.
 
\tabref{7-3} shows the types that are available to the user.

\begin{tbl}{Types Available to the STATUS Command}{l p{10cm}}
\textbf{Type} & \textbf{Definition} \\
\hline
CONFIG		&	Displays the module name, node name, power-on hours, power
				cycles, and unit failures. \\
LOGS		&	Displays the last eleven machine and bugchecks on the module.
				Included in the display are the processor registers (D0-D7, A0-A7),
 				the time and date of each failure (if available, otherwise the
				date 17 November 1858 is displayed), and some of the hardware
				registers. \\
DATALINK	&	Displays the data link counters. \\
PATHS		&	Displays available path information (open virtual circuits) from
				the point of view of the controller. The information displayed
				includes the remote node names, DSSI IDs, software type and
				version, and counters for the messages/datagrams sent and/or
				recieved. \\
\end{tbl}

Example:

\begin{verbatim}
    PARAMS> STAT CONF

    Configuration:
      Node R39JNA is an RF71 controller
      Software RFX V102 built on 1-NOV-1988 13:39:09
      Electronics module name is EN0O00245
      In 41 power-on hours, power has cycled 1 times
      System time is 12-NOV-1988 15:00:12

    PARAMS>
\end{verbatim}
\newpage
\section{WRITE}

This command is used to record the changes you have made using
PARAMS back to nonvolatile memory. The WRITE\Index{WRITE} command is similar in
nature to the VMS SYSGEN WRITE command. There are no parameters
available. The syntax is simply WRITE at the PARAMS> prompt.

However, when using the WRITE command you must be aware of the
system and/or ISE requirements and use the command accordingly or it
may not succeed in writing the changes.

The WRITE command may fail for one of the following reasons:

\begin{itemize}
\item	The user altered a parameter that required the unit, and the unit
		cannot be acquired (for example, it's not in the available state with
		respect to the host). Changing the unit number is an example of a
		parameter that requires the unit.

\item	The user altered a parameter that required a controller initialization,
		and the user replied negatively to the request for reboot. Changing
		the node name or the allocation class are examples of parameters that
		require controller initialization.

\item	Initial drive calibrations were in progress on the unit. The use of the
		WRITE command is inhibited while these calibrations are running.
\end{itemize} 

\section{EXIT}

The EXIT\Index{EXIT} command terminates the PARAMS local program. The text
``Exiting...'' appears on the screen.

The EXIT command is executed by typing either EXIT or \keystroke{CTRL/Z}.
