HP Serviceguard Storage Management Suite Version A.04.01.01 for HP-UX 11i v3 Release Notes, June 2014

6. Rejoin the upgraded node to the cluster. You can do this in Serviceguard Manager or use the
following command:
# cmrunnode
7. Repeat steps 2 to 5 for each node in the cluster.
8. After all the nodes are upgraded to the new product version, run the following command on
any of the nodes:
# cfsruutil finish
For more information, see the cfsruutil(1m) manpage.
Limitations
• During rolling upgrade, you cannot modify the hardware configuration, including the cluster’s
network configuration.
• You cannot modify the cluster or package configuration until the upgrade is complete. If you
need to modify the configuration, upgrade all the nodes to the latest patch, then modify the
configuration file and copy it to all the nodes.
• None of the features of the newer release of Serviceguard are allowed until all nodes have
been upgraded.
• Rolling upgrades are not intended as a means of using mixed releases of Serviceguard SMS.
HP strongly recommends you to upgrade all cluster nodes to the new release or patch.
Disabling Cluster Auto-Start on Reboot
Before attempting a SG SMS bundle installation or upgrade, you must disable AUTOSTART_CMCLD.
To disable AUTOSTART_CMCLD on all cluster nodes, access the/etc/rc.cofig.d/cmcluster
file and set AUTOSTART_CMCLD to 0, (AUTOSTART_CMCLD=0).
To re-enable Automatic startup (AUTOSTART_CMCLD) after completing your SG SMS bundle
installation or upgrade, set the flag AUTOSTART_CMCLD to 1 in the /etc/rc.config.d/
cmcluster file (AUTOSTART_CMCLD=1)
For more information on AUTOSTART_CMCLD, see the Setting up Autostart Features and Performing
a Rolling Upgrade sections in Managing Serviceguard, Nineteenth Edition, available at
www.hp.com/go/hpux-serviceguard-docs → HP Serviceguard
Cluster Offline Upgrade Option for SG SMS Bundles Containing CVM/CFS
To upgrade a SG SMS CFS bundle (T2777xx, T8687xx, or T8697xx) where the supported upgrade
path in Table 5 (page 22) and Table 6 (page 23) indicates an offline upgrade is required, there
is a procedure that may work with your configuration to minimize the time that the entire cluster
is offline. This is accomplished by performing an offline upgrade on half of the cluster nodes while
the other half of the cluster nodes remain online.
NOTE: This cluster offline upgrade option is supported for upgrades to SG SMS versions A.03.01,
A.04.00 or A.04.01 only from SG SMS versions containing Serviceguard 11.19 (SG SMS versions
A.02.01, A.02.01.01 and A.03.00).
This cluster offline upgrade procedure considers the upgrade of SG SMS only. You need to take
responsibility for applications that run in the SG SMS cluster you plan to upgrade. Before starting
this procedure, make certain your computing environment and the applications running on top of
SG SMS in the cluster can accommodate being offline temporarily. You might benefit from using
Dynamic Root Disk (DRD) utilities to perform your upgrade, if your upgrade is supported with DRD.
See “Using Dynamic Root Disk Utilities (DRD) to upgrade to SG SMS A.04.01.01” (page 27) for
more information.
