checking to see if logical disks are mirrored.

I have AIX 5.1
I ran these commands and was not able to see what disk were mirrored to what. I thought this is what I should do?
lslv -m rd |more
lslv -m db |more
I get a error stating that it can't find [rd] or [db] in the device configuation databse.

Is there another way to look? I have a physcal disk bad I believe and need to check the mirroring so I know what break.
Thank you

Hi,
please check with "lsvg -l <vgname>" command if your rd and db logical volumes exist.

Following commands could be used to find out how logical volume is mirrored:

# lsvg
rootvg
# lsvg -l rootvg
rootvg:
