AdvFS I/O errors

Hi,

In the /var/adm/messages file we're receiving a number of the following
messages:

Aug 1 04:03:15 sif vmunix: AdvFS I/O error:
Aug 1 04:03:15 sif vmunix: Volume: /dev/rz9c
Aug 1 04:03:15 sif vmunix: Tag: 0xfffffff4.0000
Aug 1 04:03:15 sif vmunix: Page: 763
Aug 1 04:03:15 sif vmunix: Block: 13296
Aug 1 04:03:15 sif vmunix: Block count: 16
Aug 1 04:03:15 sif vmunix: Type of operation: Read
Aug 1 04:03:15 sif vmunix: Error: 5

It started two nights ago and when it occurs (e.g., 1:05 am, 4:03 am) it
only lasts for a few minutes then doesn't happen again until the next night
(morning). This device (/dev/rz9c) is part of our home_domain. I tried
issuing:

rmvol /dev/rz9c home_domain

and after several minutes received:

rmvol: Can't get volume file descriptors
rmvol: Error = I/O error
rmvol: Can't remove volume '/dev/rz9c' from domain 'home_domain'

I've never had to deal with these sorts of errors and was wondering what the
best approach would be. I thought I'd try running verify on this domain. I
see that I have to unmount it first (which means I have to kick all the
users off) so I'll try that after hours. Anything else I can do? The block
number seems to be the same each time so I'm wondering if it's just a bad
block. When I goto use /dev/rz9 again I think I'll use partitions (e.g.,
a,b,d,e,f) instead of the whole thing (partition c) so that if this error
occurs I can just remove the partition that this error is occuring on. Is
that the right approach?

Thanks for your help,
Andy
