HP Serviceguard Version A.11.19 Release Notes, March 2009
• The cluster is not using Veritas CVM or CFS.
• If you are updating nodes from HP–UX 11i v2 to 11i v3, you must use update-ux;
cold install is not supported in this context.
• If you are updating nodes from HP–UX 11i v2 to 11i v3, and the Serviceguard
version bundled with the HP-UX Operating Environment (OE) is later than the
one already installed, rolling upgrade restrictions apply (see “Rules and Restrictions
for Clusters in Transition” (page 47)).
Recommendations
In addition to the above Rules and Restrictions for Heterogeneous Clusters, HP strongly
recommends the following:
• All the nodes on a given HP-UX version should be running the same Fusion release,
at the same patch level; that is, the 11i v2 nodes should all be running the same
11i v2 Fusion release at the same patch level, and the 11i v3 nodes should all be
running the same 11i v3 Fusion release at the same patch level.
• All nodes should be at the same Serviceguard patch level.
CAUTION: If you introduce a node running a lower patch level than that of the
existing nodes, any new functionality introduced in the higher-level patch will
cease to be available until that higher-level patch is installed on all nodes.
• All nodes should be running the same patch levels for other products used by the
cluster.
