I have ordered 40 GB LUN,
How can i get that newly added LUN into LVM and extend the file system.

It is ext3 file system. Please give me the steps. Attached are my PVDISPLAY and LVDISPLAY outputs.

to add new disk to LVM

1) create a pv using "pvcreate /dev/sdx"
2) Then you can create a new vg on this PV using vgcreate commmand
else
If you want this PV to be a part of existing VG then you have to use vgextend command to include this PV in the existing VG

man pages will help you to get all the option you may want to use.

Thanks

Shalom,

ioscan the system after the disk has been added.

insf -C disk

Bottom line is a system boot is the way to get the disk recognized then its pvcreate vgeextend lvcreate

You only run into trouble if the new disk exceeds vg capacity then you have to vgexport and vgcreate from scratch.

pvscan replaces the ioscan I posted. I thought I was in HP-UX forums.

Sorry.
