HP Serviceguard Storage Management Suite A.04.01 Release Notes (March 2012)

◦ ckpt_cfs_mount_point /cfs1
◦ ckpt_mount_options "node1=cluster node2=cluster"
◦ ckpt_primary_policy node1 node2
2. Configure the appropriate dependency parameters of the checkpoint:
◦ dependency_name cfspkg1
◦ dependency_condition cfspkg1 = UP
◦ dependency_location same_node
3. Check the package configuration file: cmcheckconf -P
/etc/cmcluster/ckpt1.ascii
4. Apply the package configuration file: cmapplyconf -P
/etc/cmcluster/ckpt1.ascii
5. Run the checkpoint package: cmrunpkg ckpt1 (if /cfs1 is a CFS mount point,
/cfs1/ckpt2 becomes a nested mount check point)
• Creating a snapshot mount point:
Create a package configuration file for the snapshot image: cmmakepkg -m
sg/cfs_all /etc/cmcluster/snap1.ascii
1.
2. Edit the following parameters in the snap1.ascii package configuration file:
◦ package_name snap1
◦ node_name node1
◦ snapshot_mount_point /snap1
◦ snapshot_name cvm_dg3_node1/lvol3
◦ snapshot_cfs_mount_point /cfs2
◦ snapshot_mount_options "node1=ro"
3. Configure the appropriate dependency parameters of the snapshot image:
◦ dependency_name cfspkg1
◦ dependency_condition cfspkg1 = UP
◦ dependency_location same_node
4. Check the package configuration file: cmcheckconf -P
/etc/cmcluster/snap1.ascii
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
