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.

11 RF71ISE Overview
The RF71 ISE (Figure 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.

Controls and Indicators

3.1.1 DSSI Node ID Select Switches
The RF71 ISE has a DIP switchpack located next to the DSSI connector
that is used to assign a DSSI node ID number to the ISE. Each device on
the DSSI bus must be assigned a unique node ID 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 Table 3-1).

Address

1Up is toward the HDA, down is toward the module.

2Normally assigned to a host node.

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 Section 3.2 to select the DSSI node ID.
3.1.2 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.

Controls and Indicators

3-3

The READY LED is turned off during a seek until the drive heads are
on 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.

3.1.3 FAULT lndicator
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 the successful completion
of POST, this indicator is turned off.

3.2 Operator Control Panel (OCP)
When the RF'71 ISE is installed in a BA213, BA215, or R215F enclosure,

the operator interface is a control panel on the enclosure. Figure 3-2
shows the OCP. Its functions are described in Table 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, however, that the DSSI node ID
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 plugs without reinitializing
the ISE by a power-up or reset, the new DSSI address is not
recognized.

CAUTION

Do not install two plugs with the same number on the OCP.

4.3.4 Installing the RF71 ISE
CAUTION
The RF71 ISE is susceptible to electrostatic damage. Do not
handle it unless you are wearing an antistatic wrist strap that is
properly grounded to the system cabinet. When you have removed
the ISE from its shipping container, place it on an antistatic pad.
Use the static-protective Field Service kit (PN 29-26248).
1.

Install the upper and lower shock mounts in the mass storage bay
using the procedure outlined in Section 4.1.3.

CAUTION
Make sure you install the shock mounts shipped with the device.
Check the part number against Table 2-1. Installing the wrong
shock mounts may result in damage to the ISE.
2.

Install the slide rails using the four screws provided. Refer to

Figure 4-5 for the location of the screws.

Slide the ISE into the mass storage bay (drive module to the left) and
hand tighten the slide rail screws.
Connect the power cable to the ISE.

3.

CAUTION
Make sure you use the screws provided. Longer screws may
damage the ISE.

Use the 10-conductor cable provided to connect the ISE to the OCP.
Connect the DSSI cable to the ISE.

Replace the signal distribution assembly and the media faceplate.
Install the correct drive select plug on the OCP.

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

5.1

Verifying the Correct Operation of an ISE

1. 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.

Replace all panels on the enclosure.

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

4. 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
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.

5-1

Verification

5-2

Once the READY LED lights, access the local program DRVTST using

the following procedure:

For a MicroVAX running VMS Version 5.0 or later, type the
following command:
$ SET HOST/DUP/SERVER=MSCP$DUP/TASK=DRVTST node-name

where:

node-name = the node name of the device

Add the qualifieffiiflogafilename.ext 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.

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

>>> 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:
>>>

SHOW DSSI

NOTE

To abort or prematurely terminate
the program and return

control to the system, press [CTRL/C] or [CTRL/

Once DRVTST passes, use PARAMS to set device parameters such as

node name and allocation class.

Fill out a LARS form to complete the installation.

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

6.1

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 initialized, 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:
1.

Controller errors - These are errors 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
errors is that the red FAULT LED lights.

6-2

Diagnostics

2. 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.

6.2 Device Resident Diagnostics

The RF71 ISE uses the fgfiéwing local programs to run device diagnostics.

These programs use the Diagnostic Utility Protocol (DUP) standard
dialogue.

DIRECT - provides the directory of available local programs

DRVTST - verifies that the hardware is functioning properly

DRVEXR - exercises the RF30 ISE

HISTRY - displays information retained by the ISE

ERASE - erases all user data from the ISE

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
*

@ - question

|- information

T - termination

FE - fatal error.

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.
