Example 2
If the SRN is 24104, the device (in theory) is connected to adapter port 1
(shown asA2 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 devices are, therefore, the SSAadapter and pdisk1.
3. (from step 2)
The problem is in the SSAlink between the two devices that you identified in step 2
on page 450.
Exchange, in the sequence shown, the following FRUs for new FRUs. Ensure that
for each FRU exchange, you go to “MAP 2410: SSARepair Verification”on
page475 to verify the repair.
a. One of the two devices that are identified by the SRN (see “Exchanging Disk
Drives”on page 319).
b. The other of the two devices.
c. The internal SSAconnections of the enclosure or enclosures in which the
devices are installed.
d. The external SSAcable.
