<cvm_dg_vol_name> 4500m
Configuring the Storage Device using VERITAS CVM
Complete the following procedure on the CVM cluster master node in the Source Disk Site to set
up the CVM disk group volumes:
1. Initialize the source disks of the replication pair.
# /etc/vx/bin/vxdisksetup -i <replicated_disk_1>
# /etc/vx/bin/vxdisksetup -i <replicated_disk_2>
2. Create a disk group for the complex workload data.
# vxdg –s init <cvm_dg_name> <replicated_disk_1> <replicated_disk_2>
3. Activate the CVM disk group on all the nodes in the Source Disk Site CVM sub-cluster.
# vxdg -g <cvm_dg_name> set activation=sw
4. Create a volume from the disk group.
# vxassist -g <cvm_dg_name> make\ <cvm_dg_vol_name> 4500m
5. Create Serviceguard Disk Group modular MNP packages for the disk group.
IMPORTANT: VERITAS CVM disk groups must be configured in a dedicated modular MNP
package using the cvm_dg attribute. This modular MNP package must be configured to have a
package dependency on the SG-CFS-pkg SMNP package.
Metrocluster SADTA does not support configuring Legacy style packages for managing VERITAS
CVM disk groups.
Complete the following steps to create a Modular package for a CVM disk group:
1. Create a package configuration file using the following modules:
# cmmakepkg -m sg/multi_node -m sg/dependency -m\
sg/resource -m \
sg/volume_group <cvm_dg_pkg_name>.conf
2. Edit the configuration file and specify values for the following attributes as below:
package_name <cvm_dg_pkg_name>
package_type multi_node
cvm_dg <cvm_dg_name>
cvm_activation_cmd "vxdg -g \${DiskGroup}
set activation=sharedwrite"
3. Specify the nodes in the Source Disk Site using the node_name attribute:
node_name <node1>
node_name <node2>
Where node1 and node2 are the nodes in the Source Disk Site.
4. Specify the Serviceguard dependency:
dependency_name SG-CFS-pkg_dep
dependency_condition SG-CFS-pkg=up
dependency_location same_node
5. Apply the newly created package configuration.
# cmapplyconf -v -P <cvm_dg_pkg_name>.conf
