Root Disk Mirror in HPUX 11.31 vg00

Locate disks

/usr/sbin/ioscan -fNnkC disk (to find out boot disk and empty disk for me /dev/dsk/c2t1d0 is empty disk)

ioscan -m lun

Locate Slice

/usr/sbin/ioscan -m dsf


Activate disk
pvcreate -fB /dev/dsk/c2t1d0

extend vg
sam-> vg -> vg00-> extendvg  or vgextend rootvg /dev/dsk/c2t1d0

then vgdisplay -v vg00 (first disk will be main disk and second disk will be empty disk)
