Michelle,
We have been told in the past by AIX HW support that these are 'link errors'.
Indeed they used to be flagged as such in the errpt output. I think
they result from a timing issue - momentarily, the disk becomes
invisible to the SSA adapter(s) - and as such are harmless. However,
Patrick is correct, they are curable by upgrading disk and adapter microcode.

~>The Advance SerialRaid Adaptors Users Guide and
~>Maintenance Information has this blurb in reference to
~>FE9E9357:
~>
~> When the error is logged against a disk drive,
~> it indicates that the adaptor has detected a
~> failure on the disk drive. It is possible,
~> however, that the failure was detected because
~> the disk drive was unavailable for a short
~> period. Run the error log analysis to
~> determine whether the disk drvie should be
~> exchanged for a new one.
~>
~>I run ssa_ela, and get no errors. No errors on lspv
~>of the hdisk, no errors on the volume group, nothing
~>else that I can find.
~>
~>I've been assuming that the problem is as stated
~>above, "the failure was detected because the disk
~>drive was unavailable for a short period", since I can
~>find no other errors. The first time I noticed it
~>(back in December?), we called IBM and had them come
~>out. They ran a diagnostic on the disk and came up
~>with no errors. However, since I seem to continue to
~>get them occasionally, maybe it's a real problem?
~>What else can I check?
