Hello, I have a disk in lsm that is in state "online error private". (error shown by voldisk list) On this single disk there is a volume, on top of it an advfs domain that can't no loger be mounted. Is it possible to recover from this situation? Unix 4.0 This issue is urgent. Thanks, Gea 793-2240 [Posted by WWW Notes gateway]

This usually means that the disk has experienced some I/O error while
updating its configuration database. Were any errors recorded in the
log? Also, could you provide more details about your configuration?
The output from the following commands would help:
# volprint -ht
# voldisk list
# voldg list rootdg

The problem appears to be that disk rza11 is missing. Did it check-in
at the last boot? What is its current status? Can you access it
outside of LSM? If the disk really has suffered a hardware failure and
the data on it no longer available you will need to replace the disk
and restore the data from backups.
On another note, your LSM configuration is less than optimal. You have
a diskgroup with 10 disks and 11 configuration databases. For a
diskgroup of this size, four dbs are sufficient. I would consider
eliminating the config dbs on rza1, rza2, rza3, rza9, and rza10.
The command to do this for rza1 would be:
voldisk moddb rza1 nconfig=0
You would then substitute "rza1" with each of the other disks.
I chose to eliminate the 'rza' disks because these had smaller private
regions than the other disks. You may choose to eliminate the config
dbs from other disks to spread the config dbs over multiple
controllers. In no case do you need to have two copies of the db on a
single disk.

You might run sys_check to see what it tells you about this setup... http://www-unix.zk3.dec.com/tuning/tools/sys_check/sys_check.html | |||||
