Basicly most of people sent me methods to show only "imported" disk
groups.
Danielle Georgette sent me a detailed procedure to know "deported" disk
groups but it did not work for me may be it will work for others (It
only show imported dgs). Here is the procedure:
========================================================================
=
1. Make sure all the devices visible to the system are registered with
hwmgr by running scu scan edt.
2. Look at the output of hwmgr -view dev, identify the disks.
3. Check the disklabels of all disk devices using disklabel -r dsk#
4. Identify partitions in use by LSM as indicated in the disklabel.
5. Run volprint on each disk (for fully encapsulated disks)/or LSM
partition. Examples shown for both.
The diskgroup the disk/partition belongs to will be visible in the
"Group:" field.
>From this you can build up a list of diskgroups and what
disks/partitions belong in them.

Dsk1 is an LSM encapsulated disk (g and h are pub/priv partitions using
all available space) :

Subject: LSM Basic question !
Hi Managers,
Sorry for this basic question,
I just need to know a method to know all Disk groups on a given machine
even the "deported" ones !
Thanks
Levi
