ignite question

Hi,

I have an L2000 with 2 disks which are mirrored using HP MirrorUX.
Two partions are stale on one of the disks. I would like to create an Ignite tape prior to replacing the disk, but Ignite is failing due to the LVM issue. Is there a way to force Ignite to ignore the bad disk and go ahead and create the tape?

Thanks

Are the stale partitions on the mirror disk? If so, break the mirror then do the ignite.

Hi,

Yes, you can break the mirror and take ignite backup. It should work without problems there after.

break the mirror before running ignite.

lvreduce -m 0 /dev/vgnn/lvnn
vgreduce /dev/vgnn /dev/dsk/cntndn

Goodluck,

Either way will work.

You do not need to break the mirror prior to making the ignite make_tape_recovery while the disk is working.

If the disk has already failed, then you have no choice but to break the mirror on all logical volumes and vgreduce vg00 to exclude the bad disk.

Then you can make_tape_recovery, change out the bad disk, boot off the tape and put everything back together.

Just understand that if the disk is not bad, make_tape_recovery will back up and restore lvm mirrors.
