Upgrading to a Different SG SMS Bundle
Upgrades to HP Serviceguard Storage Management Suite bundles can fall into any one of three
categories:
• Rolling Upgrade - The upgrade is done online. This means individual cluster nodes can leave
the cluster, be upgraded, and re-join the cluster one at a time. At no time will the entire cluster
be halted. Until the last cluster node is upgraded, nodes with different versions of SG SMS
can be running in the cluster.
• Offline Upgrade - The cluster nodes must be taken offline and all nodes must be upgraded
with the same SG SMS bundle - for an alternative offline upgrade procedure that minimizes
downtime, see “Cluster Offline Upgrade Option for SG SMS Bundles Containing CVM/CFS”
(page 26).
• Uninstall - The currently installed SG SMS bundle must be uninstalled before a new SG SMS
bundle can be installed, then the software must be reconfigured (the cluster must also be
reconfigured, if a CVM/CFS bundle is installed).
Table 5 and Table 6 shows all supported upgrade paths - these upgrade paths do not require an
uninstall of the current SG SMS product version.
IMPORTANT: Any change from one SG SMS product to another that is not represented in Table 5
and Table 6 will require an uninstall of the current SG SMS product, installation of a different SG
SMS product, then the software must be reconfigured (the cluster must also be reconfigured, if a
CVM/CFS bundle is installed).
Keep the following guidelines in mind when viewing Table 5 and Table 6:
• The arrows (→) in the rows in Table 5 and Table 6 show the supported upgrade paths for
various SG SMS bundles.
• The SG SMS version number (for example, A.03.00), and dependencies (HP-UX version,
Serviceguard version, Veritas™ Storage Foundation version), are listed at the top of the column
for each SG SMS version - followed by the bundle numbers that are available within that SG
SMS version, (for example, T2774DB).
