Re: Can Ignite provide non-disruptive cloning to alternate boot disk?
I would think that just plain old dd should do the trick!

Re: Can Ignite provide non-disruptive cloning to alternate boot disk?
Follow this procedure:
pvcreate -B /dev/rdsk/c1t0d0 #use real disk
mkboot -l /dev/rdsk/c1t0d0
mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c1t0d0 # use real disk
# mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?
If you are running 64-bit OS:
# mkboot -b /usr/sbin/diag/lif/updatediaglif2 -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?
vgextend /dev/vg00 /dev/dsk/c1t0d0 # same thing
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t0d0
# real disk. repeat for other lvols
lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap
lvlnboot -d /dev/vg00/lvol2 #swap/dump
lvlnboot -b /dev/vg00/lvol1
lvlnboot -R
lvlnboot -v
setboot
setboot -a 52.1.0 # second disk
This will set up an alternate boot disk.
What you do prior to maintenance is to break the mirrors with lvsplit, protecting them.
Can Ignite be used to do this?
Yes, you can use make_net_recovery to copy the vg00 configuration to another server. You can use make_tape_recovery to make a bootable recovery tape.

Re: Can Ignite provide non-disruptive cloning to alternate boot disk?
Yes you can use ignite to do this. Please try to create a tape with -i option with make_recovery.
Now try to boot thru the tape, and change the default disk, the OS would go and reside on the new disk.
But I feel the DD disks are a better choice.
Thanks

Re: Can Ignite provide non-disruptive cloning to alternate boot disk?
The disk will not be bootable in the current system because the hardware path will be different.
The mirror/split solution will create a bootable drive. After the split the second disk will be bootable, even though there will be logical volumes requireing rename.
Makeing an Ignite tape is not disruptive. We do it twice a week and it does not effect system performance or machine operation.
