Mirroring lvol's

[Bob Verity]

Has anyone seen the following error? I tried this same command on a different 10.20 box and it works. The version of the lvextend commands is the same on both boxes.
usmdok19:/->lvextend -m
1 /dev/vg00/lvol1 /dev/dsk/c2t8d0
Usage: lvextend
[-A Autobackup]
{-l LogicalExtentsNumber |
-L LogicalVolumeSize}
LogicalVolumePath [ PhysicalVolumePath... | PhysicalVolumeGroupName... ]
"m": Illegal option.

Meaning you don't have Mirror/UX installed. Confirm this by ..

# swlist -l bundle|grep Mirror

Hi Bob,

Stupid question but do you have MirrorDisk/UX on the system where it's failing?

Hi Bob,

Do you have Mirror/UX installed on your server ? Check that through 'swlist' command.

it looks like the system does not have MirrorDisk installed. Make sure you have the software installed.

swlist | grep -i mirror.

If not you will have to install MirrorDisk/UX

Hi Bob,

you should have mirror disk/UX installed on your system to use the "m" option in lvextend. Check the mirror disk availability on your system using swlist.

Hope this helps.

Thanks for your input. The difference between the system s is the lack of the Mirror ux software.
