replacing bad mirrored root drive

[Mark Smith T-Systems]

We will be replacing a bad mirrored root drive, NOTHING can be done with the drive itself, such as:
lvreduce -k -m 0
vgreduce
vgcfgbackup
because it locks up the terminal window anytime the drive is touched.

It is hot swappable in an N-class (without On Line Replacement).

I see no other way than to stop any running applications, yank out the bad drive, and plug in the new drive.

My steps to restore and mirror the new drive are:
vgcfgrestore
vgsync vg00
mkboot

That process seems OK to me but I am looking for any other ideas, just in case.

Thanks!

Hi Mark,

I don't have the link handy, but there is a document called "When Good Disks Go Bad". this is a good document to keep around. You should be able to find it on the ITRC.

Hope this helps,
