a. Observe the SRN that sent you to this MAP. The last three characters are in the
format PAA, where P is the number of the SSA adapter port, and AA is the SSA
address of the device).
Note the value of PAA in the SRN. For example:
If the SRN is 24002, PAA = 002.
If the SRN is 24104, PAA = 104.
b. Observe the Link Verification screen, and identify the physical device that is
represented by PAA in the SRN. This device is the first of the two devices that
are connected by the failing link.
If the SRN is in the series 21xxx through 29xxx, the second device of the two is
located at PAA−1.
If the SRN is 33xxx, the second device of the two is located at PAA+1.
Note: If the SSA address (AA) in the SRN is higher than the highest SSA
address that is displayed for the adapter port (P), that address is the
address of the SSA adapter.
Read through the following examples if you need help in identifying the device,
then go to 3 on page 453. Otherwise, go directly to 3 on page 453.
