Hello to all Gurus,
Thanks to everyone who replied. I got plenty of answers but this one
puts them all in a nutshell:
----
Hi,
Please try to run the full fsck and see if it can
repair the vxfs filesystem.
fsck -Fvxfs -o full -Y /dev/dsk/dwh_backup02
Otherwise only option is to restore from backup.

So, after running the fscx -o full quite a lot of stuff was restored but
the folder structure was destroyed. In the end I had to clean the disk
and restore the week old stuff from backups.

Maybe it's worth explaining that the SAN is an HP
EVA, thus there are no
hotspares that I could use. We trust(ed) on the EVA
internal RAID5 &
VRAID but losing the FC was something we didn't
think of.

Subject: repair a SAN disk?
Hello all Gurus out there,
I have a Sol8 server connected to a FC SAN. The FC
was lost for a moment
during a copy which made the vxfs disk corrupt.
This is the first time I'm trying to salvage a disk
so I don't have many
means to do it. Perhaps you could help me out?
The problem is this:
Server1:~$ mount /data1/dwh/BACKUP02
UX:vxfs mount: ERROR: /dev/dsk/dwh_backup02 is
corrupted. needs checking
Server1:~$ fsck /dev/dsk/dwh_backup02
UX:vxfs fsck: WARNING: file system had I/O error(s)
on meta-data.
UX:vxfs fsck: ERROR: OLT extent 1 has bad checksum
read of OLT copy failed
UX:vxfs fsck: ERROR: cannot initialize aggregate
file system check failure, aborting ...
Any ideas what could I try next?
