Re: Damaged hd5

verify this, else the results could be pretty disastrous. Its been a while, i think it's:

remove the bad one:
rmlv hd5

use mkboot to create a new hd5:
http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.doc/cmds/aixcmds3/mkboot.htm

add a copy to the bad disk:
mklvcopy hd5 2 diskwithnohd5

do a bosboot:
bosboot -ad /dev/diskwithnohd5

change the bootlist
bootlist -m normal disk1 disk2

Subject: Damaged hd5

One of my servers (AIX 5.2 ML07) had a disk problem. I've got a couple of
block-relocation and related errors.

Unfortunately, rootvg wasn't mirrored as in the past there wasn't enough
disk space. However, there have been some changes and with a bit of
shuffling around I was able to free up a suitable disk and ran a mirrorvg.

Alas! It failed! All the LVs were created but hd5 and hd6 could not be
synchronised - presumably because they're on damaged portions of the disk.

I think I can deal with hd6 by doing a swapoff then deleting it and
re-creating it. But how do I deal with hd5?

Can I delete the LV then re-create it? If so, how? I'm sure I've done this
in the past - re-create a missing boot LV, anyway - but can't remember how
at the moment. I'm hoping you might be able to save me some time!

Thanks,
