Displaying Mirrored Disks

[Doug_85]

Running HP-UX 11.- Lserver

Is there a way to display what disks are mirrored to what drives. In SAM I can see the block device file and character device file for each drive. I can tell each drive is mirrored because vg00 and vg01 are on 2 separate drives. Which drive is the primary drive and which one is the mirror copy?

Thanks,
Doug

The disks themselves are not mirrored. Mirroring is done at the logical volume (LV) level.

To see which disks each LV occupies do a:

# lvdisplay -v /dev/vg??/lvol?

That will tell you which disks make up the LV.
