Lock Disk

Darren Murray — Sat, 15 Sep 2001 00:06:07 GMT

Hi,

We are using Veritas volume manager in our MC/Service guard . Does the Lock disk have to be in a LVM volume group or can it be a veritas disk group??

Cheers
Darren

Hi Darren,

The lock disk should belong to a LVM Volume Group. I don't think service guard will recognize the veritas disk group. The Lock VG and the lock PV are identified in the cluster configuration. So it would be good to have them set into LVM VG.

Hope this helps.

Thanks

I really wonder if there is any support for Veritas Volume Manager for MC/Service Guard.

MC/Service Guard has been proven for LVM. I think it's better not to become a testing LAB for HP.

Just my thought.

Hi,

I think the veritas disk group is usd under the veritas HA, high availability product from veritas. They are trying to place it on par with MC/Sg, i think.

Hope this helps.

thanks

There is a technical paper available at http://docs.hp.com under High Availability for integrating VxVM with MC/SG 11.09. It states the cluster lock disk can only be configured with an LVM VG.

That particular section of the white paper is here;

SG 11.09 with HP-UX 11.11 (11i) with a patch supports the use of VxVM volumes in packages, but NOT as a cluster lock disc. You must use an LVM lv for the lock disc.
