repair a SAN disk, revised

Hello again,

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?
