hi All
i need to know the procedure to create raid5 volume group using 3 disks from hp disk system 2120

Thank you in Advance

You can't do RAID5 with LVM, you can only do a RAID1 (+ hotspare).
The best way to do it is installing a smartarray card, supported on most HP9000 servers now.
Another chance is to use another volume manager with licenced features, like VxVM.

hi,

With smart array controllers you configure them with command line utilities like
#saconfig

Shalom,

True raid 5 is kind of tough, because you only have three disks.

If you use striping option in LVM you will achieve the same effect.
