Serviceguard Configuration for Oracle 10g RAC
Configuration File Parameters

Configuration File Parameters
You need to code specific entries for all the storage groups that you want
to use in an Oracle RAC configuration. If you are using LVM, the
OPS_VOLUME_GROUP parameter is included in the cluster ASCII file. If
you are using Veritas CVM, the STORAGE_GROUP parameter is included in
the package ASCII file. Details are as follows:
OPS_VOLUME_GROUP
The name of an LVM volume group whose disks are
attached to at least two nodes in the cluster; the disks
will be accessed by more than one node at a time using
SLVM with concurrency control provided by Oracle
RAC. Such disks are considered cluster aware.
Volume groups listed under this parameter are marked
for activation in shared mode. The entry can contain up
to 40 characters.
STORAGE_GROUP
This parameter is used for CVM disk groups. Enter the
names of all the CVM disk groups the package will use.
In the ASCII package configuration file, this parameter
is called STORAGE_GROUP.
Unlike LVM volume groups, CVM disk groups are not entered in the
cluster configuration file, they are entered in the package configuration
file.
NOTE CVM 4.x or later with CFS does not use the STORAGE_GROUP parameter
because the disk group activation is performed by the multi-node
package. CVM 3.x or 4.x and later without CFS uses the STORAGE_GROUP
parameter in the ASCII package configuration file in order to activate
the disk group (on HP-UX releases that support Veritas CFS and CVM;
see “About Veritas CFS and CVM from Symantec” on page 22).
Do not enter the names of LVM volume groups or VxVM disk groups in
the package ASCII configuration file.
