present the disk of required size from storage

1.insf -e
2.ll /dev/*group
3.mknod /dev/xxx/group c 64 minorno ( from the output from step 2 )
4.pvcreate /dev/rdsk/cxtydz
5.vgcreate -s 32 /dev/vgname /dev/dsk/cxtydz
6.lvcreate -n xxx -L size vgname
7.lvextend -L size /dev/vgname/lvname

Hi,

1. add new disks to the server
2.do ioscan to findout the newly added disks
3. insf -eCdisk to create device file
4. pvcreate (eg. pvcreate /dev/rdsk/disk5)
5. create VG
mkdir /dev/vgname
mknod /dev/vgname/group c 64 0x0n0000
the minor number should be unique
use ll /dev/*/group to findout the exixting groupfile minor numbers
vgcreate /dev/vgname /dev/dsk/diskname.

Hello Zishan,

I think you are new to this stuff.

I recommend these steps.

How to add Hard drives in server.if this is not a SAN setup. if you have free local disk slots, then you will insert in those slots.

if your intention is just to increase the space.

login as root
# sam or (smh)
Scroll down to go to Disks and file Systems

here you can create volume groups, logical volumes etc.

its pretty easy.
