\chapter{General Information}
This chapter describes the RF71 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 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 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{RF71-BA213-IMAGE}{The BA213 Enclosure}
\section{The BA215 Enclosure}
EK-RF71D-IM-001.tex
The 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}
\section{The R215F Enclosure}
The RF215F 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}
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}
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{RF71-SWITCHES}{RF71 ISE Switch and LED Locations}
\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 IDE 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 (OCP). 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.
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}
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)}
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}
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.
\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.
To learn the DSSI node address and node names of the DSSI devices, use
the following console command:
\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}.}
\begin{enumerate}[resume]
\item Once DRVTST passes, use PARAMS to set device parameters such as
node name and allocation class.
\item Fill out a LARS form to complete the installation.
\end{enumerate}
\chapter{Diagnostics}
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) 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 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 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.
\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.
\subsection{DIRECT}
DIRECT provides a directory of all available local programs resident in
the RF71 ISE. An example of a DIRECT program display is:

\end{ttfig*}
\subsection{DRVTST}
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}}{\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}}{\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.
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.
