HP Serviceguard Storage Management Suite Version A.02.01 for HP-UX 11iv3 Release Notes, Edition 2 (May 2010)

• 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 27).
• 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 1-5 shows all supported upgrade paths - these upgrade paths do not require an uninstall
of the current SG SMS product version. Any change from one SG SMS product to another that
is not represented in Table 1-5 will require an uninstall of the current SG SMS product. Keep the
following guidelines in mind when viewing Table 1-5:
• The arrows (→) in the rows in Table 1-5 show the supported upgrade paths for various SG
SMS bundles.
• The SG SMS version number (for example, A.02.00), 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, T2771CA).
• You can do rolling upgrades of any SG SMS bundles within the same horizontal row if the
letter R is in the upgrade path.
Starting with SG SMS version A.02.00 to A.02.01 upgrades, 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.01.00
T2771BA bundle to a SG SMS version A.02.01 T2771CA 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.
NOTE: Table 1-5 (page 26), is current as of the publication date of these Release Notes.
The most recent information on supported bundle upgrade paths is available in the HP
Serviceguard Storage Management Suite Bundles - Supported Upgrade Paths Matrix available in
the Support Matrixes section at: http://docs.hp.com/en/
ha.html#HP%20Serviceguard%20Storage%20Management%20Suite
• Upgrade paths that are not listed in Table 1-5 will require an uninstall of the SG SMS bundle,
before a different SG SMS bundle can be installed and configured.
