Mirror utilities

[JUP]

Hi

I'm running HPUX 11.23 Itanium 2.
I have a disk array mirrored - first disk is mirrored onto two other disks.

I would like to know if there is a utility program that allows the operator to view the mirror status of a disk (ie. logical volumes).

The reason is that I pulled out one disk and re-inserted it a while later to test the mirroring. The mirror s/w rebuilt the disks ok but at times slowed the system down.

Is there a monitor that I can view to see what is actually happening - what percent is complete in the re-syncing etc....

Thanks in advance

after re-insert it will write whole thing to inserted disk (since mirror is already defined for that disk), hence it was slow when you re-inserted.

to view mirrored status vgdisplay is the command

You can see the mirror status using
#lvdisplay -v /dev/vg00/ |grep stale |wc -l


this will give you number of stale PE, means remaining PE to be sync. If you replace stale with active that will give you number of PE sync.
