HP Serviceguard Storage Management Suite A.03.02 Release Notes (March 2012)

5. Apply the package configuration file: cmapplyconf -P
/etc/cmcluster/snap1.ascii
6. Run the snapshot package: cmrunpkg snap1
• Creating a snapshot nested mount point:
From the previous example, edit the ckpt1.ascii package configuration file to add a
nested snapshot mount point to an existing Modular CFS package:
1.
◦ snapshot_mount_point /cfs2/snap2
◦ snapshot_name cvm_dg3_node1/lvol4
◦ snapshot_cfs_mount_point /cfs2
◦ snapshot_mount_options "node1=ro"
2. Configure the appropriate dependency parameters of the snapshot image:
◦ dependency_name cfspkg1
◦ dependency_condition cfspkg1 = UP
◦ dependency_location same_node
3. Check the package configuration file: cmcheckconf -P
/etc/cmcluster/snap1.ascii
4. Apply the package configuration file: cmapplyconf -P
/etc/cmcluster/snap1.ascii
5. Run the snapshot package: cmrunpkg snap1 (if /cfs2 is a CFS mount point, /cfs2/snap2
becomes a nested snapshot mount point)
NOTE: Adding a snapshot mount point to a Modular CFS package, or deleting a snapshot
mount point from a Modular CFS package, is an offline operation.

Suite A.04.xx
Adding a Node to a CFS Cluster
The following example illustrates how you can add one node (node3) to a cluster consisting of two
CFS nodes (node1 and node2):
1. Ensure that the new node (node3) is connected to the storage. Ensure that all CVM disks used
in other nodes are seen by the new node (node3).
2. Ensure that the new node is connected to appropriate heartbeat networks, the same as the
other nodes in the cluster. The new node must be running the same version of the HP-UX OS,
and it is recommended that you run the same fusion level and patch levels as all other nodes
in the cluster.
3. Install the same version of SG SMS and Serviceguard on the new node as is installed on the
other nodes in the cluster. Make sure that the new node has all of the patches that have been
installed on the other nodes in the cluster.
4. Run vxinstall to complete the configuration of VxVM (if you have not already done this).
5. Probe for the new node using cmquerycl, for example: cmquerycl –C cluster.conf
–n node1 –n node2 –n node3
6. Edit the cluster name and other required cluster configuration parameters as required in the
cluster configuration file cluster.conf .
