page 314.)
SSA adapter card (See the
installation guide and the service
guide for the using system.)

Description: Async code 04 has been received.
A software error has probably occurred.
Action: Go to “Software and Microcode Errors”
on page 411 before exchanging any FRUs.
2A005 6-pack assembly (See “Removing
Six-Position SCSI (SES) or SSA Disk
Drive Bays” on page 347.)
– 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.
v If a device is missing, go to “SSA Maintenance
Analysis Procedures (MAPs)” on page 70 to
isolate the problem.
v If no device is missing, the problem might have
been caused by a temporary, or partial, loss of
power to the SSA hot-swap disk drive.
2A006 Disk drive module (See “Removing
Hot-Plug SSA Disk Drives” on
page 314.)
6-pack assembly (See “Removing
Six-Position SCSI (SES) or SSA Disk
Drive Bays” on page 347.)
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:
v If the failing device is an SSA hot-swap disk
drive, go to “SSA Maintenance Analysis
Procedures (MAPs)” on page 70, exchange the
disk drive module.
v If the failing device is not an SSA hot-swap
disk drive, go to the service information for that
device.
2A106 6-pack assembly (See “Removing
Six-Position SCSI (SES) or SSA Disk
Drive Bays” on page 347.)
100 Description: Async code 06 has been received.
This code indicates that 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.
