issue with lvmerge

[naths]

hello All,
Recently, I have upgraded a 11.00 server to 11.11. Before upgrading on safer side, I used lvsplit command to split the mirror disks, after the upgrade was done, couple of weeks later, when I try to do an lvmerge I get the following error. Could some one please tell me why?.

vinegar:/# lvmerge
lvmerge: Error, "lvmerge" is not a valid LVM command.

Do you have the MirrorDisk/UX software installed? lvmerge requires the MirrorDisk software. If the software isn't there the command will probably not be there.

# swlist -l product |grep -i mirror

If MirrorDisk doesn't show up, you have your reason.

Correction:

MirrorDisk may not show up if you use the '-l product' in swlist as I did above.

Instead you can try:

# swlist | grep -i mirror

or

# swlist -l bundle | grep -i mirror

Hi:

The manpages for 'lvmerge' clearly note that "This command requires the installation of the optional HP MirrorDisk/UX software, which is not included in the standard HP-UX operating system."

Regards!

If it is foundation OS you will not get mirroring by default . you need to install the mirror software first and than try.

Hello,

It is seems to be of non availability of Mirror Ux. I wonder if your root disk is mirrored. Is it ?
