PVG Strict mirroring of non-root disks

[Sagar Sirdesai]

Hi
I've existing vg01 with 2 disks and 5 lvols
/dev/dsk/c9t11d0
/dev/dsk/c9t13d0

I've added two more disks in from different storage.

I plan to mirroring the lvols in vg01 to new disks froma new storage possibly PVG strict.

Please advise if this possible on an existing VG.

Are the LV's currently mirrored? If not, then this is definitely possible.

You can change the mirror policy to PVG-strict on the LV's by doing:

# lvchange -s g /dev/vg01/lvol1
(or whatever your LV names are).

You'll have to do this for each LV since mirroring is done at an LV level.

Then you can do your 'lvextend -m 1' to mirror the LVs.

Since you want to use PVGs, make sure you create your PVGs in the /etc/lvmpvg file.

# man lvmpvg for more information.
