Product Description
The StorageServer 100 provides an economical way to access a large amount of
traditionally offline information such as archival or backup files, or records that
were previously stored on paper or microfilm.

The StorageServer 100 contains multifunctional optical drives. The drives can
operate in either rewritable mode or write-once mode, depending on the type of
disk that is inserted into the drive. The StorageServer 100 software is designed
to use the drives with rewritable disks only. The data on the disks can be written
and erased repeatedly.
The SterageServer 100 is a small, compact autochanger that contains the
following:
e

An autochanger mechanism (moves disks in and out of storage slots within
the cabinet)

Two 5.25-inch optical disk drives

A mail slot used to insert and remove disks

This chapter describes how to remove and reinstall mass storage drawers in the

DECsystem 5900 cabinet.
When installing the StorageServer 100 under the following conditions, it can be
necessary to move a mass storage drawer and then reinstall it:

The DECsystem 5900 is configured w:.h a single CPU, and slot 1 has a mass
storage drawer in it.

The DECsystem 5900 is configured with dual CPUs, and slot 5 or 6 has a
mass storage drawer in it.

2.1 Locating a Slot for the StorageServer 100 in the
DECsystem 5900 Cabinet
Note

A step ladder or stool is required to service the upper drawers in a
DECsystem 5900 (slots 5 and 6). Two people are needed to complete the
removal or the installation of a mass storage drawer.

The StorageServer 100 can be installed in two possibie locations on ¢ »
DECsystem 5900:

When there is only one CPU, the StorageServer 100 occupies slots ! and 2.

When there is a second optional CPU i. slot two, the StorageServe > 100
occupies slots 5 and 6.

2.2 Locating Drawers on the DECsystem 5900 Cabinet
The DECsystem 5900 is shipped from the factory with U-nut clips in place on
the cabinet rails at the proper position for all mass storage drawer slides. If
these have been removed, or were not installed, the placement of drawers may be
determined by counting the holes in the cabinet rails, beginning at the top and
counting down.

Table 2—1 shows the placement of drawers on the cabinet rails,

Reinstalling the Mass Storage Drawer 2

Use the following procedures to install the mass storage drawer 2:
Note

At least two people are required to remove or replace a drawer in the
DECsystem 5900.

Make sure that the stabilizer bar is pulled out (see Section 1.1).

Pull out the drawer slides from the cabinet until they catch in the partially

extended position (see Figure 2-14).
3.

Reach under the front of the middle slide and trip the catch upward so that
the slides may be fully extended.

While holding the catch up, extend the slides until they lock and the spring

tabs are out; you will be resting the entire drawer on these open slides, so be
sure they are firmly locked in place.
5.

With your partner on one side of the drawer and you on the other, lift it up

and place the lip on the side of the drawer on top of the slides. Line up the
holes in the side of the drawer with those on the inner part of the slide.
6.

Attach the foremost hole on the extended portion of the slide to the front
drawer hole with a hex screw.

Press in on the slide tab and close the drawer slowly until the rear slide hole

is exposed (it should be lined up with the rear drawer hole at this point).
8.

Attach the rear slide hole to the drawer with a hex screw.

(PU drawer power switch, bottom switch

Make sure both switches are turned on. Turn on the Enable Power On switch
first.

2.8 Acceptance Testing for the Mass Storage Drawer
There are some steps that you should take to verify that the system can see all
the devices connected to it; for instance, that there are no configuration or cabling
problems, and that all devices in the system are functionally in good operating
condition:
Note

The following is only a list of steps to take for acceptance testing, for more

detailed information consult the DECsystem 5900 Service Guide, and the
DECsvstem 5900 Installation Guide.

2-28

Rer ng and Reinstalling Mass Storage Drawers

Turn on the system and observe the Power-Up Self-Test (POST). No errors
should occur on the console. The Kbd and Pntr messages are not errors. The
POST will test internal system components, such as CPU, caches, memory
and TURBOchannel adapters only.
Use the config utility to make sure that you can see all the devices on the
system. Using the cnfg x command (where x = the TURBOchannel slot),
make sure that the system can recognize all the devices on the SCSI busses
and that there are no SCSI ID conflicts.
If you cannot see all the devices, check the ID settings of the devices on
that bus and make sure they are properly connected to the bus. Remember
that each SCSI bus can have only one device with a 0, 1, 2, 3, 4, 5, or 6 ID
connected.

Run the scsi/entl (SCSI controller), sssi/sdiag (send uviapnostie) and the
scsi/target tests (test SCSI devices) on the SCSI controller(s) and newly added
SCSI devices. The following are examples of the console commands to invoke
these tests:
t 3/scsi/entl

t 3/scsi/sdiag scsi_id [d] [u] (8]
t I/scsi/target ccsi_id [w] [loops/

Caution
The /w/ parameter on the scsi/target test may cause data loss; use it on
newly installed disk devices which have no data on them, or use a scratch

tape on tape devices.

Each SCSI port on the back of a DECsystem 5900 computer is marked with the
SCSI icon (see Figure 4-4):

Flgure 4~4

SCSI icon

Z5-0557-MH

The DECsystem 5900 can have up to four SCSI controllers. There is a built-in
system SCSI controller and up to three PMAZ TURBOchannel-based SCSI
controllers. The StorageServer 100 will be connected to one of these PMAZ SCSI
controllers and will use three SCSI 1D’s.
Note

The 68-hole connector at the lower left hand corner of the DECsystem
5900 computer back panel is the base system SCSI port. It may be
marked with the SCSI icon but it is not labeled with the option identifier
PMAZ. This SCSI port is used to connect system devices to the DECsystem

5900. Do not connect the StorageServer 100 SCSI cable to this port.

4-8

Installing the Rackmounted StorageServer 100

Due to possible performance issues, cable management problems, and cable
length restrictions, the StorageServer 100 should be connected to a PMAZ SCSI
controller by itself. This may require moving some SCSI devices to another SCSI
controller. See Chapter 2, Removing and Reinstalling Mass Storage Drawers
in this book, and for more information see the DECsystem 5900 Enclosure
Maintenance Manual.

To connect the SCSI cable from the StorageServer 100 to the DECsystem 5900,
refer to Figure 4-5 and follow these steps:
1.

Look at the back of the DECsystem 5900 CPU enclosure and locate the lowest

numbered available PMAZ option (marked with a SCSI icon and PMAZ-A
identifier).
Note

The option slots in the top (TURBOchannel Extender) are an extension

of TURBOchannel slot 0. It is possible for 1 PMAZ to be in the
TURBOchanne! Extender (only one of any option can be placed in
the TURBOchannel Extender.

If all the PMAZ controllers have devices connected, another PMAZ should be

added to the system or devices should be moved to make a PMAZ available
for the StorageServer 100.

Plug the 68-pin connector end of the SCSI cable into the lowest-numbered

available PMAZ SCSI port on the back of the DECsystem 5900. The connector
is keyed so that it only attaches cne way. The connector snaps in place with a
spring loaded lock.
