% Problem
100 Description: A disk drive module has detected
that one of its SSA links has failed the POSTs.
Action:
1. Use the Link Verification Service Aid to
determine where the SSA link is broken.
2. Run diagnostics in the system verification
mode to the two disk drive modules that are
nearest to, and on each side of, the place
where the link is broken. The diagnostics
show which disk drive module detected the
problem.
– Description: An async code that is not valid has
been received.
Action: Go to "Software and Microcode Errors"
on page 428.
100 Description: A disk drive module has detected
the loss of one of its power inputs.
Action:
v If the failing device is an SSA hot-swap disk
drive, exchange the 6-pack assembly.
v If the failing device is not an SSA hot-swap
disk drive, go to the service information for that
device.
100 Description: Multiple disk drive modules have
detected the loss of one of their power inputs.
Action:
v If the failing devices are SSA hot-swap disk
drives, exchange the 6-pack assembly.
v If the failing devices are not SSA hot-swap disk
drives, go to the service information for those
devices.
100 Description: A disk drive microcode error has
been detected.
Action: Go to "Software and Microcode Errors"
on page 428 before exchanging any FRUs.
100 Description: A SCSI status that is not valid has
been received.
Action: Go to "Software and Microcode Errors"
on page 428 before exchanging any FRUs.
30 Description: Excessive link reconfigurations have
30 been detected.
30 Action: Go to "MAP 2323: SSA hot-swap disk
drive Intermittent Link Verification" on page 80
before exchanging any FRUs.
