Hi Mark,

As far as I know, until now Ignite/UX didnt cover to restore the mirror, unless you did some perform something on the script before you take the make_tape_recovery backup.

Check the url below (docID : KBQA00000588) about 'How to recover a mirrored root volume with make_tape_recovery' for your reference in the future to create Ignite backup that can recover mirrored root disk :

In your case, you need to re-mirror again the primary boot disk into the secondary boot disk (mirror disk) by yourself (either manually or by using the script).

Check the url below (docID : LVMKBRC00005103) about 'How to create a Mirrored Boot Disk on PA-RISC Systems - Cookbook' for your reference :

http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000080811535

Hope this information can help you.

Cheers,
AW

Shalom Mark,

make_tape_recovery backs up mirror configuration, codewords for mirror/ux and if booted to a system with enough disk space with the same device path, will restore mirrored.

If restoring to a system with different disk configuration, you may have to re-mirror it.

Hi mark,

Here is a good script to recreate your mirror

Hi Mark because you have restored from the ignite tape you have to mirror your vg00.

check wich disk you can use in my example i used c2t2d0

pvcreate â f â B /dev/rdsk/c2t2d0
vgextend /dev/vg00 /dev/dsk/c2t2d0
mkboot /dev/rdsk/c2t2d0
mkboot â l
mkboot â a â hp-ux â lq (;0)/stand/vmunixâ /dev/rdsk/c2t2d0

for i in 1 2 3 4 5 6 7 8
do
lvextend â m 1 /dev/vg00/lvol$i
done

Check if the BDRA is correct.
/usr/sbin/lvlnboot -R /dev/vg00
Verify that the mirrors were properly created.
lvlnboot -v /dev/vg00
The output of this command is shown in a display like the following:
Boot Definitions for Volume Group /dev/vg00:
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0 (1/0/0/3/0.6.0) -- Boot Disk
/dev/dsk/c2t2d0 (1/0/1/0/0/1/1.6.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t6d0
/dev/dsk/c2t2d0
Root: lvol3 on: /dev/dsk/c0t6d0
/dev/dsk/c2t2d0
Swap: lvol2 on: /dev/dsk/c0t6d0
/dev/dsk/c2t2d0
Dump: lvol2 on: /dev/dsk/c0t6d0, 0

vgdisplay -v vg00

grtz. Mark
