Example 2
If the SRN is 24104, the device (in theory) is connected to adapter port 1 (shown as A2
on the screen). The device, however, has an SSA address of 04. That address is
higher than the highest address that is displayed for adapter port 1. The device is,
therefore, the IBM SerialRAID Adapter.
003
(From step 002)
The problem is in the SSA link between the device that you identified in Step 002 on
page 2323-2 and the device that is on the same adapter port (P), but whose SSA
address has a value of 1 less than AA (AA − 1).
For example, in Step 002 on page 2323-2, SRN 24002 identified the SSA address of
the third disk drive as 02; the address (AA − 1) of the other device on the link is,
therefore, 01. SSA address 01 is the address of the second disk drive. SRN 24002
indicates, therefore, that link errors have been detected between the second and third
disk drives.
Similarly, SRN 24104 identified the SSA RAID adapter. The SSA address of the
adapter is 04. The address of the other device is, therefore, 03. SSA address 03 is
the address of the first disk drive. SRN 24104 indicates, therefore, that link errors have
been detected between adapter port A2 and the first disk drive.
– Exchange, in the sequence shown, the following FRUs for new FRUs. Ensure that
for
each
FRU exchange, you go to “MAP 2410: SSA Repair Verification” on
page 2410-1 to verify the repair.
