Hi,

Without the rac extension for MC/serviceguard you cannot activate a volumegroup in shared mode.

Alternatives are ASM or Veritas cluster

From the man page

The vgchange command with the -c option controls the membership of one
or more volume groups in a high availability cluster. The vgchange
command with the -c and -S options control the membership of a volume
group and mark it sharable.


It does not say these commands come with SG, so you may be able to go through the LVM part of the SG setup guide and set up the volume groups properly without install SG.

If it is to work, and I have doubts you will have to issue the vgchange command on both nodes. If you can't without SG, perhaps you can install SG but not run SG.

Re: Install Oracle 10g RAC without MC/ServiceGuard

According to the documentation, you can install RAC without ServiceGuard if you use Oracle's Clusterware. The caviat here is that you cannot use LVM (no vgchange, etc). You have to use raw devices either manually or through Automatic Storage Manager. If you want to use LVM, then you must use ServiceGuard.

10g RAC Oracle includes its own clusterware and package management solution with the database product named Cluster Ready Services (CRS).

If you want to use shared logical volumes for your database then you must use HP Serviceguard and HP Serviceguard Extension for RAC.

If you don't want to use HP Serviceguard, you must use raw partitions to store the Oracle CRS files. You cannot use shared raw logical volumes to store these files without HP Serviceguard.
