LIFS are not the same on mirrored disks

[Alex Lavrov.]

Hello,
I have two disks mirrored in vg00, but for some reason LIFS area is no same on them.

What can be a reson for it and how should I fix it?

[Keith Bryson]

I've come across this recently. When you perform the mkboot command, only the absolute necessary LIF programs are copied over (the system will still boot though on the mirror). You are probably missing the diag programs.

To be honest on some servers I miss them all .... ;-\

[Keith Bryson]

Have you created the mirror using:

pvcreate -B {dev}
mkboot -l {dev}

????

This must be done for root disk mirrors.

Have no idea who an how created them.


So, to fix it I must use mkboot?

You must have misssed following. ODE tools were not copied.

mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p HPUX -p AUTO -p LABEL -p PAD
/dev/rdsk/cxtxdx

Use updatediaglif2 if it is 64 bit kernel.

Your best bet is to remove the mirror disk, then:

(c1t0d0 is used as an example)
pvcreate -B /dev/rdsk/c1t0d0
mkboot -l /dev/dsk/c1t0d0
vgextend /dev/vg00 /dev/dsk/c1t0d0

then re-mirror the LVs in the same order as the original disk.

hi Alex
what's the output of lvlnboot -v ?
when one of your vg00 disk isn't a Boot Disk, you won't be able to boot from it.
the solution is to totally remove the disk from vg00 and create it again with the -B option.

good luck.

This is the output:

This one doesn't look to bad (off-line diags missing). Use the suggestion from RAC to fix this. If you are missing ALL LIF programs on some systems, see my suggestion to fix.

Again, sae reply.

You must have misssed following. ODE tools were not copied.

mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p HPUX -p AUTO -p LABEL -p PAD
/dev/rdsk/cxtxdx

Use updatediaglif2 if it is 64 bit kernel.

I think I'll recreate the mirror from the beginning, because I see there are many problems.



Thanx a lot to all!
