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 23).
• 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 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 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 6:
• The arrows (→) in the rows in 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).
• You can do rolling upgrades of any SG SMS bundles within the same horizontal row if the
letter R is in the upgrade path.
Rolling upgrades of SG SMS bundles that include Veritas™ Cluster Volume Manager (CVM)
or Cluster File System (CFS) are allowed if only the Serviceguard version changes, and the
HP-UX and Veritas/Symantec Storage Foundation versions remain the same.
• Upgrade paths that require an Offline Upgrade, are indicated by the letter O.
• “Skipping ahead” within the row, for example, upgrading from a SG SMS version A.02.01
T2774CB bundle to a SG SMS version A.04.00 T2774EB bundle, is supported only if all of
the upgrade paths between the currently installed SG SMS version and the SG SMS version
you want to upgrade to are marked with an R.
