Mirroring a root disk on a VPAR

[EU-Admins-UNIX]

Hi

I am just mirroring a test vpars root disk.  Whem extending lvols 1, 2 & 3, I get:

root@hathor at /probkup =>lvextend -m 1 /dev/vg00/lvol1 /dev/disk/disk141
The newly allocated mirrors are now being synchronized. This operation will
take some time. Please wait ....
Logical volume "/dev/vg00/lvol1" has been successfully extended.
lvlnboot: LIF information corrupt or not present on  "/dev/disk/disk141".
Use the "mkboot" command to initialize the LIF area.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

Same for lvol2 & 3

Any idea how to rememdy this?

You need to populate the LIF area, see

When_Good_Disks_Go_Bad_WP
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01911837/c01911837.pdf

But this depends on the hardware platform (RISC vs. Integrity)

The only difference in a vpar is, you need tp specify "/stand/vpmon" instead of "/stand/vmunix" in the autofile.

It is a PA-RISC system running 11.31

I'm very weary about using these boot commands.

Please advise.

The system tells about disk124, disk141 and disk337.

Please provide

# vgdisplay -v vg00

Now do

mkboot -l /dev/rdisk/disk141

mkboot -a "hpux /stand/vpmon -a" /dev/rdisk/disk141

The check again with

# lvlnboot -v

and "lifls".

When I enetered the command

mkboot -l /dev/rdisk/disk141

I got the following, so I said no and proceeded no further..

root@hathor at /usr/local/scripts =>mkboot -l /dev/rdisk/disk141
There appear to be non-boot logical volumes on this device.
Overwriting them could destroy all the data on this device
Should the logical volumes be overwritten [y/n]? n
Please answer yes or no. Should the logical volumes be overwritten [y/n]? no

If I said yes, would I have to re-mirror all the LVs again?

Please show

lifls -l /dev/disk/disk141

Based on the warning you received I would remove the mirror from disk141, reduce it from vg00, pvcreate -f -B ... it again and start over to mirror (based on the document - see appendix - I sent you earlier).

Thanks

All re-mirrored and bootable...

Not quite sure what disk337 is doing here, it's justa snap copy of production.
