I did it for LVM. What is the procedure to mirror the root disk under VxVM?

Here is the high level procedure

1. pvcreate -B /dev/rdsk/cxtxdx
2. vgextend /dev/vg00 /dev/dsk/cxtxdx
3. mkboot /dev/rdsk/cxtxdx
4. mkboot -a "hpux (52.3.0;0)/stand/vmunix" /dev/rdsk/cxtxdx
5. lvextend -m 1 /dev/vg00/lvol1 /dev/rdsk/cxtxdx
(mirror all LVs on VG00).
6. verify by lvlnboot -v

Good luck.

Are these VxVM commands?
I used some lif command to mirror root disk for LVM, as necessary. Do I need those for VxVM also?

Jun, If you are talking about a complete root volume group (disk group) under veritas volume manger, no you don't

check the docs on docs.hp.com I use it on solaris and I don't think they will match.

Kind regards,

My current running root disk is 4GB. Can I mirror all the volumes to two 2GB sized disks, and boot to the one where rootvol and standvol live?
