% Problem
100 Description: Multiple disk drive modules
have detected the loss of one of their
power inputs.
Action:
If the failing devices are SSA Hot-

If the failing devices are not SSA Hot-
Swap Disk Drives, go to the service
information for those devices.
100 Description: A SCSI status that is not
valid has been received.
Action: Go to "Software and Microcode
Errors" on page 5-2 before exchanging
any FRUs.
100 Description: The SSA adapter card has

Action: Exchange the FRU for a new
FRU.
90 Description: An SSA device on the link is
preventing the completion of the link con-
figuration.
10 Action: If the SSA service aids are avail-
able, run the Link Verification Service Aid
to determine which device is preventing
configuration. (That device is the one
beyond the last-configured device on an
open SSA link.)
Run Set Service Mode on the failed
pdisk.
100 Description: A disk drive module has
failed.
