HP Serviceguard Storage Management Suite A.03.02 Release Notes (March 2012)

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 24).
• Uninstall - The currently installed SG SMS bundle must be uninstalled before a new SG SMS
bundle can be installed, then the software must be re-configured (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. 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. 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.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: You might benefit from using Dynamic Root Disk (DRD) utilities to perform your
uprade, if your upgrade is supported with DRD. See “Using Dynamic Root Disk Utilities (DRD)
to upgrade to SG SMS A.03.02” (page 25) for more information.
NOTE: Table 6 (page 22), 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 at:
www.hp.com/go/hpux-serviceguard-docs → HP Serviceguard Storage Management Suite
A.03.xx
• Upgrade paths that are not listed in Table 6 will require an uninstall of the SG SMS bundle,
before a different SG SMS bundle can be installed and configured.
