X-Sun-Spots-Digest: Volume 7, Issue 95, message 6 of 21

Recently, our Sun 3/260 crashed because of a power outage.  When it came
back up, we had disk read errors in our root partition.  I used diag to
tell the system about the bad sectors, and restored the lost data from my
backup tapes.  When I rebooted, ths workstation came up with no further
problems.  I figured everything is cool now, right?  Well, today, almost a
week later, I shutdown and rebooted, and got the message:

  xy0a: read retry (disk sequencer error) -- blk #495, abs blk #495

Is this a serious disk problem that I should worry about?  The system
seems to be working well.  What is a disk sequencer error?  Would diag
have to be used to fix this problem?  Any help, and or advice would be
most greatly appreciated.  I wouldn't want to have to spend half the day
recovering data again.  Thanks in advance!
