Here are the steps to follow:

1- Open the prompt.

2- ioscan -fnC disk = Search Attach disk with HP server

3- pvcreate -f /dev/rdsk/c0t1d0 = Initialize a disk for use with LVM

4- Create the device structure needed for a new volume group.
    cd /dev
    mkdir vgdata
    cd vgdata
    mknod group c 64 0x010000


5- vgcreate vgdata /dev/dsk/c0t1d0 = Create volume group vgdata


Note: if your expecting to use more than 16 physical disks use the -p option, range from 1 to 256 disks.

6- vgdisplay -v vgdata = Display volume group vgdata

7- pvcreate -f /dev/rdsk/c0t4d0 = Add another disk to volume group
   vgextend vgdata /dev/dsk/c0t4d0

8- vgreduce vgdata /dev/dsk/c0t4d0 = Remove disk from volume group
