% Problem
50 Description: Async code 03 has been
received. A software error has probably
occurred.
50 Action: Go to "Software and Microcode
Errors" on page 5-2 before exchanging
any FRUs.
50 Description: Async code 04 has been
received. A software error has probably
occurred.
50 Action: Go to "Software and Microcode
Errors" on page 5-2 before exchanging
any FRUs.
– Description: Async code 05 has been
received. This code indicates that a disk
drive module has detected a loss of
power.
Action: Use the Link Verification Service
Aid to determine if any devices are
missing from the SSA link.
If a device is missing, go to "SSA
Maintenance Analysis Procedures
(MAPs)" on page 2-65 to isolate the
problem.
If no device is missing, the problem
might have been caused by a tempo-
rary, or partial, loss of power to the
SSA Hot-Swap Disk Drive.
70 Description: Async code 06 has been
received. This code indicates that a disk
drive module has detected the loss of one
30 of its power inputs.
Action:
If the failing device is an SSA Hot-
Swap Disk Drive, go to "SSA Mainte-
nance Analysis Procedures (MAPs)"
on page 2-65, exchange the disk
drive module.
If the failing device is not an SSA Hot-
Swap Disk Drive, go to the service
information for that device.
