Hi:

The output of 'lvdisplay' offers the key. If you have truly striped, then the number of 'stripes' will be > 0. If you have mirrored, then 'Mirror copies' > 0.

Regards!

Hi,

If your using HP-UX you can see if there is
disk mirroring by utilising the lvdisplay command.
You can also use this to see if there is any
striping. The output for mirroring will be
similar to this. Note the field where it
states mirrored copies. For striping have a look in the 'stripes' field.

use the commands

vgdisplay -v vg##

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


Mirroring and striping is done at the "lvol" (Logical volume) level.
