I forgot to "pvcreate -B" my root mirror before I mirrored.

[Stuart Abramson_2]

Can I do it now, after I mirrored the root LVs?

Or is it too late and I'll have to mirror all over again?

I have it all mirrored, but it's not bootable:

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
......../dev/dsk/c0t6d0 (0/0/0/3/0.6.0) -- Boot Disk
......../dev/dsk/c4t6d0 (1/0/0/3/0.6.0)
Boot: lvol1.... on:.... /dev/dsk/c0t6d0
......................../dev/dsk/c4t6d0
Root: lvol3.... on:.... /dev/dsk/c0t6d0
......................../dev/dsk/c4t6d0
Swap: lvol2.... on:.... /dev/dsk/c0t6d0
......................../dev/dsk/c4t6d0
Dump: lvol2.... on:.... /dev/dsk/c0t6d0, 0

Hi Stuart,

I'm afraid you're going to have to start over.
The pvcreate -B reserves the space for the LIF at the proper location.

You might be able to vgcfgrestore the info from the primary to the alternate..

vgcfgrestore -n /dev/vg00 /dev/dsk/c0t6d0 /dev/dsk/c4t6d0

Otherwise, you will have to lvremove -m 1 the mirror and redo it again...

Look at it this way, more practice is always good...

Jeff is correct. You'll have to start all over. You should reduce your mirrors, reduce the PV out of the VG. Then start again with the pvcreate -B

Hi,

Since pvcreate -B needs more header space than pvcreate without bootability, you may have to start all over again.

Good Luck.

Yes, the best option available is to restart the process. You first need to reduce the mirror from all LVs and check the output of lvlnboot -v to make sure that only one disk is listed there.

This is a good cook book to follow when mirror the root TKB #LVMKBRC00005103:

That -B stands for make bootable.

Game over, reset and play again. You won't be able to boot off it until you do it all again.
