2A006 Disk drive module
Backplane 70
30
Description: Async code 06 has been
received. This code indicates that 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, go to “SSA
Maintenance Analysis Procedures
(MAPs)” on page 2-35, exchange the
disk drive module.
Ÿ
If the failing device is not an SSA
Hot-Swap Disk Drive, go to the
service information for that device.
2A106 Backplane assembly 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
backplane.
Ÿ
If the failing devices are not SSA
Hot-Swap Disk Drives, go to the
service information for those devices.
2A206 Disk drive module 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
(see “Link Verification Service Aid” on
page 3-73) 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.
2FFFF None – Description: An async code that is not
valid has been received.
Action: Go to “Software and Microcode
Errors” on page A-5.
