[Original Question Posted Below]

Thanks to Rich Quinn, Mark Neill, Amarjeet Virdi, and Mark Almeida.

Rich said to try the "preen" option with fsck - no luck
Mark N. said to specify the fstype with fsck - no luck
Mark A. pointed me to vxvol and vxmend - no luck
Amarjeet suggested I mount it read only and move the data.
        Though I was trying to avoid this it looks like it is my only option at
this time since I have 30 angry engineers stopping by my office every
couple of minutes. :)

The general concensus is that there is a bad disk. I couldn't find
anything in /var/adm/messages about this but I did find several memory
errors or maybe cpu errors...

Original Question -

[E6500, A5000 running Veritas 2.6

I have a filesystem (striped only) on an E6500. The machine crashed for
an unknown reason (nothing in /var/adm/messages) and one of the
filesystems is bad. When I run fsck I get this...

root@RAPTOR>>> fsck /dev/vx/dsk/rootdg/raptor5
** /dev/vx/dsk/rootdg/raptor5

CANNOT SEEK: BLK 31449600
CONTINUE? y

CANNOT READ: BLK 31449600
CONTINUE? y

CANNOT SEEK: BLK 31449600
CONTINUE? y

THE FOLLOWING SECTORS COULD NOT BE READ: 31449600 31449601 31449602
31449603
root@RAPTOR>>> mount /export5
mount: the state of /dev/vx/dsk/rootdg/raptor5 is not okay
        and it was attempted to be mounted read/write
mount: Please run fsck and try again

I think I can somehow repair this filesystem with either format or
veritas but am not sure how. Can anyone help me?

TIA

Will summarize
