[nitin_2]

Is s/w raid 5 supported on lvm on hp-ux 11.0 ?

Not with HP's LVM, but with Verita's version of LVM for 11 I believe you can do software RAID 5.

You can't do Raid 5 with HP's LVM but you can do striping, which I believe is Raid 1(?).

Hi Nitin,

Have a look at the thread below.

Hope this helps.

Hi:

Veritas Volume Manager (VxVM) provides Raid-5 functionality at a software level. LVM does not. Take a look, at the "VERITAS Volume Manager 3.1 Administrator's Guide" for more information.

Parity cannot be generated by LVM. It can only do mirroring. So RAID-5 is not possible with LVM. Veritas Volume manager can do this. But it is available only on 11.11 onwards.
