Hi Shalabh,
It is possbile to do subdisks moves through vmsa, but I prefer the command
line. The general command would be:
vxassist -g <diskgroup> move <volume_name> \!<spare_name> <new_disk_name>
e.g. if your setup were this:
volume: vol1
diskgroup: mydg
name of spare: mydgspare
name of new disk: mydg02
then this would move any subdisks belonging to vol1 from mydgspare to
mydg02:
vxassist -g mydg move vol1 \!mydgspare mydg02
you could then repeat this command for each volume that was
relocated. when you are done, they'll all be back on the new disk, leaving
your space the way it is.
what version of vm are you using? one of the 3.x versions comes with a
command to put stuff back the way it was (i believe).

since your volumes are redundant (ie: raid 0+1), this is an easy
task.
1) vxevac [-g <disk group>] <source diskname> <destination
diskname>
ie: vxevac -g datadg spare01 disk02
2) with the vxva gui (vm 2.6 and below), you can "drag and drop"
the sub-disks from one disk to another. i would guess that the
vmsa gui (vm 2.6 and above) would also offer the same feature.
later,
paul

Hello,
you should be able to use the 'evacute disk' operation.
Don't have access right now to a system , but the command should be
there.

Problem Description :-
> Recently one of the harddisk in a diskgroup failed . It had 3
> subdisks , put
> in 3 different plexes in 3 different volumes . All volumes are
> in RAID 0+ 1
> . We had on harddisk configured as spare and as soon as the
> disk failed ,
> spare harddisk automatically created 3 subdisks and they went
> into
> corresponding plexes and volumes which were occupied by faulty
> harddisk .
>
> Problem :- I ordered for a harddisk and replaced the faulty
> one ( vxdiskadm
> -- remove harddisk for replacement -- shutdown the system --
> Put good
> harddisk -- vxdiskadm -- replace failed harddisk ) . Now I see
> new harddisk
> with "good" status in vxva . But problem is the data of 3
> volumes is still
> placed in spare harddisk . The new harddisk ( replaced ) does

> How can I move

> harddisk
> without breaking the volume & restoring from backup media ? I

> on them ( inrespective plex/volume) .
> 2. Spare harddisk without any subdisk ( as previously )
> without any
