Figure 25 Rolling upgrade procedure for Metrocluster
The subsequent sections describe the procedures for completing a rolling upgrade for Metrocluster
configurations with SADTA. These sections describe upgrading HP Serviceguard, HP-UX, and
Metrocluster software in Metrocluster SADTA configurations.
Upgrading Metrocluster software
To perform a rolling upgrade of Metrocluster software:
1. Disable package switching for all Metrocluster packages.
2. Install the new Metrocluster software on all the nodes.
3. Enable package switching for all Metrocluster packages.
To upgrade Raid Manager software, see “Upgrading the P9000 or XP Raid Manager software
for Metrocluster with Continuous Access for P9000 and XP” (page 81).
Upgrading Metrocluster with SADTA configured
In a Metrocluster with SADTA configured, all software upgrades including Metrocluster software,
HP-UX, Serviceguard, or Serviceguard extension for RAC require additional steps to be followed.
For information about upgrading the array-specific replication management software, see
“Upgrading the P9000 or XP Raid Manager software for Metrocluster with Continuous Access for
P9000 and XP” (page 81). While upgrading, ensure that the upgrade procedure is first completed
on all the nodes in a site before upgrading the nodes in the other site.
