mirror disk

[kacou]

I made a mirror on my disk system. But with the 'lvlnboot -v' command i don't see 'boot disk'in front of the disk /dev/dsk/c3t2d0 (0/1/1/1.2.0). see below. is it correct?
---------------------------

#lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c2t0d0 (0/1/1/0.0.0) -- Boot Disk
/dev/dsk/c3t2d0 (0/1/1/1.2.0)
Boot: lvol1 on: /dev/dsk/c2t0d0
/dev/dsk/c3t2d0
Root: lvol3 on: /dev/dsk/c2t0d0
/dev/dsk/c3t2d0
Swap: lvol2 on: /dev/dsk/c2t0d0
/dev/dsk/c3t2d0
Dump: lvol2 on: /dev/dsk/c2t0d0, 0

Hi Kacou,

Have you performed "mkboot" on the mirror disk?

[kacou]

yes!
i execute mkboot /dev/rdsk/c3t2d0

Hi Kacou,

Can you send me the list of steps that you followed for mirroring your disk. Maybe you have missed a step or two. Refer to page no. 24 of the attached document for a step by step procedure of mirroring.

[kacou]

Hope you have done pvcreate with -B which is required for creating bootable disk.

# pvcreate -B /dev/dsk/c3t2d0

[Vihang.]

Its pvcreate -B /dev/rdsk/c3t2d0 (remember the r)

Hi Kacou,

Your procedure seems to be correct. Just verify your logs if you had enabled logging to check if you have missed anything.

I'm sure you did only

pvcreate /dev...

but it must be

pvcreate -B /dev...

Because of this you don't have a boot area.

I would assume you get some errors while doing the "mkboot" commands.

Better to release the mirror again (caution, keep the correct disk!) and start over.
