Follow the steps

Assume that your new disk is c1t6d0

1. #pvcreate /dev/rdsk/c1t6d0
2. #mknod /dev/vg03/group c 64 0X030000
3. #vgcreate /dev/vg03 /dev/dsk/c1d0s2
4. #lvcreate -L 9126 -n lvdata /dev/vg03
5. #newfs -F vxfs /dev/vg03/rlvdata
6. #mkdir /data
7. #mount /dev/vg03/lvdata /data

Hi,

One addition to SK's good anser.

Before you add the disk to the server, save or print an output from

# ioscan -fnCdisk

Add the disk to the server.

# ioscan -fnCdisk

now you have the cxtydz numbers.

Yes.Use ioscan -fnC disk to find out the cxtxdx of the disk which you have added.
One more thing in vgcreate you can specifiey the max no of disks , max_pe
by

#vgcreate -e -p /dev/vg03 /dev/dsk/c1d0s2

eg: #vgcreate -e 9126 -p 5 /dev/vg03 /dev/dsk/c1d0s2
