Thanks to Mike Smith, who sent me the note his notes from once having a
similar problem.
Basically, the solution comes in a few steps:
_Fix LSM_
1. From the menus given in 'voldiskadm', remove and replace the faulty
disk. The voldiskadm utility will disklabel the disk and everything!
2. Either 'volume maint', 'volume resync', 'volume init active' or 'volume
init zero' the volume to enable the volume and make it active. (I ended up
using all these commands, don't know which one did the job. It was at this
point that I was asking for help.)
_Caution_
Do NOT 'mount' or 'verify' advfs volumes until you rebuild advfs. If you
do, the system crashes, and you need to boot from CD before you can try
fixing. That is, if you have your volumes noted in /etc/fstab like I do ...
_Fix advfs_
The advfs domain which held the faulty disk was lost when the disk when
faulty. Will need to rebuild this domain.
1. Note your naming convention, sizes, etc. if you need to. /etc/fstab
helps.
2. 'rmfdmn' to remove the domain.
3. 'mkfdmn' to recreate the domain.
4. 'mkfset' to recreate the file sets.
_Restore_
vrestore the files belonging to this file domain back onto it.

Subject: Replacing disks under LSM
I could not find the summary to this problem, but I think it might help what
in what I am looking for, for the next stage of getting my LSM volume back
after a disk was replaced. Could someone please help?
Many thanks.
Replacing disks under LSM?
Hi all,
I have 4 disks in a stripeset, called data , one went faulty, used
voldiskadm to replace disk.
All went well, except that the when you try a mount -a, it say something
about bad files type.
If you go into lsm gui and you try and start volumes it says that Vol
datavol has no CLEAN or non-volatile Active plexes.
I have deported and imported the disk groups, recreated the disk groups.
Any ideas as to what the problem might be?
Many thanks in advance,
Mike Smith
