Hello managers ...
I am having some problems with two Tru64 5.0a boxes, and a shared disk
array between them. I'll try to make it brief, but if someone has any
insight as to what could be causing these troubles, I would be grateful.
The shared disk array [six disks, striped and mirrored] is attached to the
two boxes, and we are running in an ad-hoc cluster environment using
heartbeat. One box is the master and has the disk array or shelf [using
AdvFS and LSM] imported, mounted, and running user email, home directories,
etc.
Our situation is that the shelf will become unavailable. It shows as being
mounted when you run df but if you try to cd into once of the directories
that reside on the shelf, you get a 'Permission Denied' error. I can
deport and then re-import the shelf, and it becomes available again, but
only for a few minutes.
I have previously deleted and then recreated the AdvFS file domains and
file sets, then restored from tape, and it ran for about 24 hours. since
the first crash after that it will only run for a few minutes. I am
running verify as I type.
I have checked the uerf logs but I don't see anything that jumps out at me,
there are some CAM SCSI errors [samples below] but I don't know if they are
indicative of the problem. I am thinking a bad disk maybe, but would
appreciate any advice.
Thanks for your time!
