[SUMMARY] T3 Array - Veritas Volume Manage help!!!



With one disk failed and one failing, I was unable to reconstruct the
failed disk. So I replaced both faulty disks and issued a vol verify
v0 fix rate 8. This finished (eventually) and all disks were OK. I
then ran a fsck on the device. the fsck ran all night . There were
some recovered directories, but in the end, I just did a newfs on the
entire volume and restored from tape.

The volume is created by the T3 and all disks managed by the T3.
Volume Managers simply had a volume of the volume. That does not make
sense to me. It seems I could have just mounted the array directly? I
left it the way it was. It already caused me enough grief.

To: sunmanagers@xxxxxxxxxxxxxxx


I have inherited supporting an T3 array with 9 disks (no spares)
Firmware 1.16 and Veritas Volume Manager (running on an Ultra 60). Of
course this is mount as /home and affects 60 - 100 folks...

We apparently have two disk issues. One failed and cannot
reconstruct, the other is stuck reading one block. The same block,
over and over.. hundreds of messages...

I am trying to figure out how to check/repair the disk with the read
error. I am pretty unfamiliar with the commands on Veritas and the
T3. I see some potentially useful commands like vol verify fix, but
am not sure if I use that or some vx command.

Disk 4 is failed and cannot reconstruct according to the syslog
messages. fru status simply indicates it is rebuilding but the LED
and syslog say it failed. I don't believe I can rely on the fru
command.

Disk 2 has these errors... I don't believe I can reconstruct disk 3
until disk 2 is repaired...

I would appreciate any help/insight.

Here are some messages I am receiving...
