HP Serviceguard Storage Management Suite A.04.00.01 for HP-UX 11i v3 Release Notes (December 2011)

remaining, larger group of nodes to Group B. For example, if the cluster contains 9 nodes,
assign (9 - 1)/2 = 4 nodes to Group A, and assign the remaining 5 nodes to Group B.
We will use a 3 node cluster as an example for explaining this offline upgrade procedure. For a
3 node cluster, Group A will contain Node 1, and Group B will contain Node 2 and Node 3.
NOTE: Steps 1, and 2 in this procedure can be performed on multiple nodes in parallel, or on
one node at a time, before continuing to step 3.
1. Move all application failover packages that can be moved from Group A nodes, to Group B
nodes.
2. Halt the Group A cluster nodes and upgrade them to the new SMS version:
a. Node 1 > cmhaltnode –f node1
b. Perform an offline upgrade of the Group A nodes (Node 1 in this example).
3. Gracefully halt application packages running on Group B nodes, before halting the cluster
on the Group B nodes.
4. Halt the cluster on the Group B nodes:
a. Node 2 or Node 3> cmhaltcl -f
5. Start the cluster on the Group A cluster nodes (these are the nodes where the SG SMS version
has already been upgraded):
a. Node 1 > cmruncl –f –n node1
NOTE: Steps 6, 7, and 8 in this procedure can be performed on multiple nodes in parallel,
or on one node at a time, before continuing to step 9.
6. Perform an offline upgrade of the Group B nodes (Node 2 and Node 3) to the same SG SMS
version that the Group A nodes were upgraded to.
7. Re-join the Group B nodes to the cluster, one at a time:
a. Node 2 > cmrunnode node2
b. Node 3 > cmrunnode node3
8. Redistribute the application failover packages over ALL of the active cluster nodes (Group A
and Group B nodes).
9. Optional steps must be performed on the CVM master/CFS primary nodes to upgrade to the
new CVM and CFS protocol/layout versions (refer to the VxVM and VxFS Administrators
Guides for details):
• vxdctl upgrade to upgrade CVM protocol version
• vxdg upgrade <diskgroup> to upgrade disk group version
• vxupgrade <mountpoint> to upgrade to new file system layout version
