Mirroring a boot disk with LSM
I have a operating system tru64 version 5.1B.
I have installed LSM license .
The boot disk was installed using LSM .
I can see the plexes and everything using the dxlsm& (dsk0).
Now I want to add a second disk as mirror to protect the boot disk.
Some guide to do that ,
Commands , guides using the GUI interface to do these tasks.
Thank you
W.S

Re: Mirroring a boot disk with LSM
Do not know how to do from GUI.
But general procedure shold be something like:
(If the swap space is on the boot disk):
# volrootmir -a dsk2
This creates a mirror on dsk2 for all the volumes on the boot disk.
(If the swap space is on a separate disk):
# volrootmir -a swap=dsk5 dsk2
This creates a mirror on dsk2 for all the volumes on the boot disk and
creates a mirror on dsk5 for the swap volume.
Note that this procedure does not add a log plex (DRL) to the root and swap
volumes.

Re: Mirroring a boot disk with LSM
Hello,
Please make sure,
* The target mirror disk is as large as,
or larger than, the boot disk.
* Mirror disk is not in use by LSM, has
a disklabel and "fstype" for all the
partitions is marked "unused".
Now execute "volrootmir" as suggested in
the above reply.
The next time the system is shut down,
add the mirrored root disk as the backup
boot disk. If dka0 is the boot disk and
dkb0 is the mirrored root disk,
>>> set bootdef_dev dka0, dkb0
If there is a problem starting from dka0,
the system will attempt to start from the
mirror, dkb0.
Sincerely,
Manju
