a.Log in as root on one node of the primary cluster.
b.Change to your own directory:
#cd <your own directory>
c.Copy the file:
#cp /opt/cmconcl/scripts/ccrac.config ccrac.config.mycopy
d.Edit the file ccrac.config.mycopy to suit your environment. The following parameters must be edited:
CCRAC_ENV - fully qualified Metrocluster environment file name. This file naming convention is required by the Metrocluster software. It must be appended with _<DataReplication>.env where <DataReplication> is the name of the data replication scheme being used. See the Metrocluster documents for the environment file naming convention.
This parameter is mandatory
CCRAC_SLVM_VGS - SLVM volume groups configured for the device specified in the above environment file for variable DEVICE_GROUP. These are the volume groups used by the associated RAC instance packages. It is important that all of the volume groups configured for the specified DEVICE_GROUP are listed. If only partial of the configured volume groups are listed, the device will not be prepared properly and the storage will result in an inconsistent state.
This parameter is mandatory when SLVM volume groups are used. This parameter must not be declared when only CVM disk groups are used.
CCRAC_CVM_DGS - CVM disk groups configured for the device specified in the above environment file for variable DEVICE_GROUP. These are the disk groups used by the associated RAC instance packages. It is important that all of the disk groups configured for the specified DEVICE_GROUP are listed. If configured disk groups are partially listed, the device will not be prepared properly and the storage results in an inconsistent state.
This parameter is mandatory when CVM disk groups or CFS file syatems are used. This parameter cannot be declared when SLVM volume groups are used.
CCRAC_INSTANCE_PKGS - the names of the configured RAC instance packages accessing in parallel the database stored in the specified volume groups.
This parameter is mandatory.
CCRAC_CLUSTER - Serviceguard cluster name configured as the primary cluster of the corresponding RAC instance package set.
This parameter is mandatory.
CCRAC_ENV_LOG - logfile specification for the storage preparation output.
This parameter is optional. If not specified, ${CCRAC_ENV}.log used.Sample setup:
CCRAC_ENV[0]=/etc/cmconcl/ccrac/db1/db1EnvFile_xpca.env CCRAC_SLVM_VGS[0]=ccracvg1 ccracvg2 CCRAC_INSTANCE_PKGS[0]=ccracPkg1 ccracPkg2 CCRAC_CLUSTER[0]=PriCluster1 CCRAC_ENV_LOG[0]=/tmp/db1_prep.log
