Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

4. Create the volume group:
vgcreate /dev/ccvg /dev/c0t10d0
5. Activate the volume group:
vgchange -a y ccvg
6. Create the logical volume:
lvcreate -L 250M ccvg
Run the following command to create a file system on the volume:
mkfs vxfs /dev/ccvg/lvol1
Complete the following procedure to export the volume group configuration and import the volume
group on all the nodes at the recovery cluster:
1. On the node where you created the volume, deactivate the volume group and export the VG
configuration in preview mode to a file:
vgchange -a n ccvg
vgexport -m /tmp/ccvg.map -p ccvg
2. Copy the file to all the nodes:
rcp /tmp/ccvg.map node1:/tmp
3. On each node, create the volume group directory and the group special file:
mkdir /dev/ccvg
mknod /dev/ccvg/group c 64 0x060000
4. Import the volume group from the map file:
vgimport -m /tmp/ccvg.map -v
Configuring a Monitor Package for the Maintenance Feature
Configure the Continentalclusters monitor package using the template scripts available in the /opt/
cmconcl/scripts/ directory:
1. Create the /etc/cmcluster/ccmonpkg directory on all nodes in the recovery cluster.
2. On any node in the recovery cluster, copy the package configuration and control file template
from the /opt/cmconcl/scripts directory to the /etc/cmcluster directory:
cp /opt/cmconcl/scripts/ccmonpkg.*
3. In the ccmonpkg.cntl monitor package control file, specify the volume group for the VG
parameter in the VOLUME GROUPS section:
VG[0]="ccvg"
4. In the ccmonpkg.cntl monitor package control file, specify a file system path and the logical
volume name under the FILE SYSTEM section. The file system path should be the value
configured for the CONTINENTAL_CLUSTER_STATE_DIR parameter in the Continentalclusters
configuration file. This path should be created and reserved on all nodes in the
Continentalcluster.
LV[0]=/dev/ccvg/lvol1;
FS[0]=/opt/cmconcl/statedir;
FS_MOUNT_OPT[0]="-o rw";
FS_UMOUNT_OPT[0]="";
FS_FSCK_OPT[0]="";
FS_TYPE[0]="vxfs"
5. Distribute the monitor package control file to all nodes in the recovery cluster.
6. Apply the monitor package configuration.
