6.

Does only one power supply have its DC PWR LED on?

No

Go to step 7.

Yes

a.

Exchange, for a new one, the power supply whose DC PWR LED remains illuminated.

b.

Go to step 7.

7.

Is the disk subsystem still powered on?

No

The problem is solved.

Yes

Call for assistance.

MAP 2340: 7031-D24 or 7031-T24 SCSI bus

You are here because the host system cannot access any SCSI device (disk drive module or enclosure
services) in a 7031-D24 or 7031-T24 disk subsystem.

Attention:

Do not remove power from the host system or the disk subsystem unless you are directed to

in the following procedures. Power cables and external SCSI cables that connect the disk subsystem to the
host system can be disconnected while that system is running.

1.

Observe the SCSI Bus Split switch.

Is the disk subsystem powered on?

No

Ensure that a SCSI cable is attached to a powered system, and the disk subsystem is powered
on. Go to step 2.

Yes

Go to step 2.

2.

Is the yellow LED illuminated on the SCSI repeater card?

No

Go to step 3.

Yes

Replace the SCSI interface card. Go to step 3.

3.

Is the green power LED illuminated on the SCSI repeater card?

No

Go to “MAP 2020: 7031-D24 or 7031-T24 power” on page 36.

Yes

Go to step 4.

4.

Is the SCSI interface card a dual SCSI interface card?

No

Go to step 5.

Yes

Disconnect one of the SCSI cables, go to step 5.

5.

Note the positions of all the disk drive modules and the dummy disk drive modules so that you can
reinstall the modules into their correct slots later.

a.

Remove all of the disk drive modules.

b.

Go to step 6.

6.

Can the host system access enclosure services?

No

In the sequence shown, exchange the following FRUs for new FRUs. Ensure that for each FRU
exchange, you check whether you can access the disk drive module, to verify the repair.

a.

External SCSI cable

b.

SCSI interface card assembly

c.
