Error Description
ABECECFD
Link errors might be detected by any node in the SSA loop. The
adapter is notified of these errors. It performs any necessary
error recovery, and logs the error. Link errors are normally
associated with some other failure on the SSA loop. Link errors
might be logged when other devices on the loop are switched on
or off, or when cables or devices are disconnected during
service activity. Intermittent link errors are not serious. If many
link errors occur, however, one of the SSA links might be going
to fail. Run error log analysis to determine whether any repair
action is needed.

SSA devices are normally configured in a closed loop. The loop
consists of a series of links, each link connecting two SSA
devices. A device can be an adapter card or a disk drive. If this
loop becomes broken, the alternative signal path round the loop
is automatically used. A link might be broken if:
v A device is removed from the loop
v A device on the loop is reset or switched off, or it fails
v An SSA cable is removed, or it fails
Each SSA device has a Ready light that indicates the
operational status of the SSA loop to which that device is
attached. The light is permanently on when the device can
communicate with the two SSA devices that are logically next to
it on the SSA loop. The light flashes if the device can
communicate with only one of those two devices. The light is off
if the device cannot communicate with either of the two SSA
devices. Usually, an SSA device is present at each side of the
point where the SSA loop is broken. Each of those devices has
its Ready light flashing.

The adapter has passed error log data for a disk drive to the
device driver error logger, but the disk drive to which the data is
related is not configured into the using system. This problem
usually occurs because the disk drive was not available to the
adapter when the cfgmgr command was previously run.

A user procedure has not been performed correctly. Use the
SRN to determine the procedure that has caused the problem.
91FBD5DB
The software has detected an unexpected condition. If you have
just installed the SSA subsystem, ensure that the latest versions
of microcode and software have been installed. If the system is
still operational and you have any hot spare disk drives attached
to the adapter, an automatic dump might have been performed.
Run ssa_getdump -l to see if any dump data is present.
Software errors can result from hardware failures. Always solve
hardware problems, therefore, before looking for software errors.
