system failure

Hi Gang,

I recently had a v880 die in a bad way (bad way = bare metal restore).
I worked with Sun for a long time in the hopes of avoiding the
reinstall+restore. I had the machine back online but when I rebooted to
try and fix a cron problem the system refused to boot. I had set up a
SDS mirror for the primary drives and booting off the secondary also
exhibited the same problem. The only way I was able to bring it back
online was to boot from cdrom, break the mirror and use the standard
block device (not the metadevice).

After further troubleshooting the cron problem (the "bad user" problem)
I tracked it down to the shadow file and a *LK* account which should not
have been locked. I also noticed many other accounts which are normally
NP had been changed to *LK*. I have a theory that this could have been
a cause of my initial failure as well as my last failure. (and may also
explain some strange mountall problems I've been seeing)

Has anyone come across anything similar in their experience? Could
turning on auditing have made those changes in my shadow file (I'm
doubtful of this but you never know)?

It would also be worth noting that Sun was unable to analyze the core
file as it was incomplete.
