you have to check out this document

You must have missed some steps which mirroring the root disk or replacing.

mkboot /dev/rdsk/cxtydz

mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/cxtydz

this will work


for PA system.

1) vgcfgrestore -n /dev/vg00 /dev/rdsk/cxtydz
2) vgchange -a y vg00
3) mkboot /dev/rdsk/cxtydz
4) mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/cxtydz
5) vgsync vg00
6) lvlnboot -Rv


This will work :)

looks like , you have not used -B option with pvcreate. so the boot volume may not be created.
please check

Hi Suresh,

its a PA Risc or Itanium?

[Torsten.]

disk 1 0/0/0/0.1.0 sdisk CLAIMED DEVICE HP Virtual Disk
/dev/dsk/c0t1d0 /dev/dsk/c0t1d0s2 /dev/rdsk/c0t1d0 /dev/rdsk/c0t1d0s2
/dev/dsk/c0t1d0s1 /dev/dsk/c0t1d0s3 /dev/rdsk/c0t1d0s1 /dev/rdsk/c0t1d0s3




This is a virtual machine running on Itanium server.


You MUST not include

/dev/dsk/c0t1d0

into vg00, but

/dev/dsk/c0t1d0s2


otherwise this disk will NEVER boot.

Hi All,

In VMs as per HP Recommendation we should not assing the disks directly to the VM and it should be mirroed as the Host level and we should assign the LV to the guest
