ALT-PATH Booted - Do I Break LVM Mirroring... to bad disk?

[D Block 2]

Rebooted on my ALT (rp7400) using LVM. Are there any Next Steps to split the mirror from the PRI boot device ?

- split the mirror stopping mirror to bad disk
- hot-swap the bad disk
- turn on mirroring again
- reboot back on PRI

Just looking for best practices here.

I'm pretty much in agreement with your approach.

I've gotten away without your first step though that has involved substantial pain.

Tom,

In a nutshell, it's:

replace,
vgcfgrestore,
sync,
go on with life.

I have never broken a mirror on a root disk failure...

if the disk is truly dead...You may have to do all these steps.. but possibly only the last 3...

mkboot /dev/rdsk/c4t6d0
mkboot -a "hpux -lq" /dev/rdsk/c4t6d0
lifcp /dev/dsk/c4t6d0:AUTO
mkboot -b updatediaglif -p ISL -p AUTO -p HPUX -p LABEL /dev/rdsk/c4t6d0
mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p LABEL /dev/rdsk/c4t6d0

vgcfgrestore -n /dev/vg00 /dev/rdsk/c4t6d0
vgchange -a y /dev/vg00
vgsync /dev/vg00
