connect the harddisk .
check whether they found or not by
ioscan -fnc disk.
it will list all the hard disks attached.
just prepare the hard disk to be created in a VG by.
pvcreate -f /dev/rdsk/"pathname"
repeat the step on all the hard disks u have connected
so the PV structure has been writed on the disk (PVRA).
create directory which to be the name of your new VG
in /dev directory
create the device file for the VG . so that they can access
the VG asa file.
mknod /dev/dsk/"path name" c 64 0x0100000.
then create the volume group using vgcreate.
vgcreate /dev/vgo1 /dev/dsk/c0t0 /dev/dsk/"pathname" .
likewise attach all the hard disks to be addes to the
activate the VG using vgchange -a y /dev/vg01
this is the procedure to create simple volume group///
After that we need to create th logical volumes along with
