how to removing a boot disk

Mauro Gatti — Wed, 22 Sep 2004 02:50:03 GMT

Hi all,
I have to remove one of two boot disks physically from my server.
The boot disks are mirrored so I first reduced all lv mirrored (lvreduce -m 0 lvxxx pvxxx) and then I put off disk from my server.
Unluckly at next boot my system went in panic.
I suppose I forgot something to do...
Could you help me?

Thank You

Hi,

You forget to remove disk from volume group
(vgreduce). After disk removal quorum requirment will not meet and server will not boot.

Boot in LVM maintenance mode and remove disk from VG using vgreduce.

reboot the system in without quroum .
reduce the disk from vg00

Remove physical volume /dev/dsk/c0t1d0 from volume group /dev/vg00:

vgreduce /dev/vg00 /dev/dsk/c0t1d0
