Unable to boot from mirror disk on x86 server configured under VxVM

Hi,

Can you help me on booting x86 server configured under VxVM. Server boots fine normally from both the disks but if I try to boot server from mirror disk without starting veritas, then it does not boot.

vxplex -g rootdg dis var-02
vxplex -g rootdg dis swapvol-02
vxplex -g rootdg dis rootvol-02
vxprint -g rootdg
mount /dev/dsk/c1t5d0s0 /mnt
pwd
fsck -y /dev/dsk/c1t5d0s0
fsck -y /dev/dsk/c1t5d0s0
mount /dev/dsk/c1t5d0s0 /mnt

Mount the mirror disk in /mnt and take the backup of system and vfstab file .

# mount /dev/dsk/c1t0d0s0 /mnt
# cd /mnt/etc
# cp -p system system.date(Today date)
# cp -p vfstab vfstab.date(Today date)

Copy the vfstab.prevm file to the miirrord disk vfstab file .To make the disk bootable without Veritas.

#cp /mnt/etc/vfstab.prevm /mnt/etc/vfstab


bash-3.00# cat /mnt/etc/vfstab

Note : Server is unable to boot from Mirror disk c1t5d0 when booted out of veritas.

in /mnt/etc/system, what say the line rootdev?

Have you checked VTOC. Is it same as before ?
