2A106 Backplane assembly (See
“SCSI or SSA Backplane” on
page 7-65.) 100 Description: Async code 06 has been
received. This code indicates that multiple
disk drive modules have detected the loss
of one of its their power inputs.
Action:
Ÿ
If the failing devices are SSA Hot-
Swap Disk Drives, exchange the back-
plane.
Ÿ
If the failing devices are not SSA Hot-
Swap Disk Drives, go to the service
information for those devices.
2A206 Disk drive module (See
“Hot-Swappable Disk Drives”
on page 7-13.) 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 verifica-
tion 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.
2FFFF None – Description: An async code that is not
valid has been received.
Action: Go to “Software and Microcode
Errors” on page 5-2.
300C0 Backplane (See “SCSI or
SSA Backplane” on
page 7-65.) 100 Description: A disk drive module has
detected the loss of one of its power
inputs.
Action:
Ÿ
If the failing device is an SSA Hot-
Swap Disk Drive, exchange the back-
plane.
Ÿ
If the failing device is not an SSA Hot-
Swap Disk Drive, go to the service
information for that device.
