managing lvm on 11.23

[khilari]

Hi guys, i wanted to know the difference between disk management in 11.11 to 11.23. Can any one tell how to initialize a disk in 11.23 and how to put it under lvm in 11.23.
Thanks

Hi:

LVM management is the same under 11.11 and 11.23 with a few enhancements possible in 11.23 --- 'vgmodify' and the ability to create striped/mirrored logical volumes. To enable these features on 11.23, you need PHCO_36744 together with PHKL_31500 and PHKL_32095.

Regards!

There's no difference between 11.11 and 11.23.

You still use the same commands:

pvcreate
lvcreate
vgcreate

lvextend
vgextend

fsadm
newfs

[Geoff Wild]

Commands are basically the same...

man on

lvcreate(1M),lvchange(1M), lvdisplay(1M), lvextend(1M), lvreduce(1M), lvremove(1M),
pvchange(1M).

One major difference is the LVM Volume Group Dynamic LUN expansion (DLE) / vgmodify feature, see

If you compare LVM in 11.11 and 11.23 on a PA-RISC based HP9000 system there is not so mauch difference, but if you compare HP9000 and Itanium based Integrity servers there is a big difference in the boot disk layout and the mirroring procedure, see
