[Veritas-vx] I/O errors on an vxfs filesystem

[Robinson, Greg]

Hi all,

Similar to Balki, we appear to have a dead disk in our storage array, but my question is, how do I determine which disk is dead?

we found vxfs had disabled /export/home on one of our servers this morning (Solaris 8, vxvm 3.5 MP1).

df showed cannot stat: I/O error.

vxprint -hrt showed everything was fine, nothing disabled.

After a umount -f and a fsck -o full, I could remount the volume.  It is still showing a bad inode:

hostname: vxfs: vx_ilisterr: vx_iread_3 - /export/home filesystem error reading inode 151228
hostname: vxfs: vx_ialloc - /export/home filesystem inode 151228 not free
hostname: vxfs: vx_ilisterr: vx_ialloc - /export/home filesystem error reading inode 151228

This disk is attached to a Sun A3510, and it a single LUN, then is is "sliced" at the host using vxvm.  How can I determine which disk I need to replace in the raid set?

There are no errors on the 3510, and there is no read flashing light or alarm (yes I checked the obvious).

Thankx for any help,

Greg.
