ignite restore - mirrored volumes

[Joe Profaizer]

Just completed a total restore via ignite to our development server which had mirrored volume groups and logical volumes. The ignite restore didn't put the groups and volumes back together. Is there a way to do so, other than executing the respective vg & lv commands upon system recovery?

Ignite does not treat any mirroring.
You have to set up mirrors manually after restoring.

[Darrel Louis]

Ignite doesn't restore the mirror automaticly.
You can test it with the post_config_cmd, in the
/var/opt/ignite/recovery/config.recover

I've the following on one of my systems below:

post_config_cmd="
/usr/sbin/vgimport -v -m /etc/lvmconf/vg01.mapfile /dev/vg01 /dev/dsk/c0t9d0 /dev/dsk/c0t10d0
/usr/sbin/vgchange -a y /dev/vg01
/usr/sbin/vgcfgbackup /dev/vg01
/usr/sbin/vgcfgbackup /dev/vg00
"


In your case it would look like, to restore a mirror:
post_config_cmd="
vgreduce /dev/vg00 /dev/dsk/c1t6d0
pvcreate -f -B /dev/rdsk/c1t6d0
vgextend /dev/vg00 /dev/dsk/c1t6d0
mkboot /dev/rdsk/c1t6d0
mkboot -a \"hpux -lq\" /dev/rdsk/c1t6d0
mkboot -a \"hpux -lq\" /dev/rdsk/c0t6d0


lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t6d0
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c1t6d0
...etc
lvlvnboot -R
"

You have to mirror your disks first and then make an Ignite UX recovery tape. This ensures that whenever your recover your server, your mirrored disk will still be intact. I guess you must have made the recovery tape before activating the mirror disk utility

[Patrick Wallek]

As Rainer and Darrel said, Ignite does NOT do anything with mirroring by default.

I actually prefer it this way. If something happens where I have to restore the system from the tape, I want the system back up as soon as possible. I don't want to wait on it to remirror and of the disks. I can always do that on the fly after the system is back up.

Another reason I don't want Ignite remirroring automatically is that if I use the Ignite tape to upgrade my OS drives to larger drives (I have recently gone from 8 2GB drives to 2 18GB drives). In this case the post_recovery script will not do you any good unless you tailor it for the new drives before you start.

Just my 2 cents.

You should go and have a look at the following URL:

http://www.software.hp.com/products/IUX/docs.html

It has a Whitepaper on [Ignite-UX and Mirrored Disks]. Or maybe it is still available under /opt/ignite/share/doc/diskmirror.pdf.

I hope this helps.
