Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

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 Replication software in Metrocluster configurations.
Rolling Upgrade in Metrocluster Configurations
This section describes the procedures for completing a rolling upgrade in Metrocluster with and
without SADTA configured. This section also discusses how to complete a rolling upgrade of HP
Serviceguard, HP-UX, and Metrocluster Replication software in Metrocluster configurations.
Following are the topics discussed in this section:
• “Upgrading Metrocluster without SADTA Configured” (page 512)
• “Upgrading Metrocluster with SADTA Configured” (page 512)
Upgrading Metrocluster without SADTA Configured
To perform a rolling upgrade of Metrocluster without SADTA configured, complete the following
steps:
1. Disable package switching for all Metrocluster packages.
2. Install the new Metrocluster software on all nodes.
3. Enable package switching for all Metrocluster packages.
To upgrade the HP-UX version, SGeRAC or HP Serviceguard software, complete the procedures
outlined in the Managing HP Serviceguard, Nineteenth Edition, or Using Serviceguard Extension
for RAC, 8th Edition, available at http://www.hp.com/go/hpux-serviceguard-docs —> HP
Serviceguard Extension for RAC.
To upgrade the array-specific replication management software, see “Upgrading Replication
Management Software” (page 513).
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 on upgrading the array-specific replication management software, see “Upgrading
Replication Management Software” (page 513). While upgrading, ensure that the upgrade procedure
is first completed on all nodes in a site prior to upgrading nodes in the other site.
Complete the following procedure to upgrade Metrocluster software, HP Serviceguard, SGeRAC,
or HP-UX:
1. Identify the sites in the Metrocluster and the associated nodes.
# cmviewcl -l node
Select a site to perform the rolling upgrade.
2. Select a node in a site to perform the rolling upgrade.
# cmviewcl –l node -S <site_name>
3. View all the packages running on the selected node.
# cmviewcl -l package -n `hostname`
Identify the Site Controller Packages that are running on the node.
4. Move all Site Controller Packages running on the selected node to a different node in the
same site using DETACH halt mode.
For more information on moving the Site Controller Package, see “Moving the Site Controller
Package to a Node at the Local Site” (page 396).
5. Verify that there are no Site Controller Packages running on the node.
# cmviewcl -l package -n `hostname'
6. If SGeRAC is configured, then halt the Oracle software (RAC, CRS, Clusterware, and OPS)
on the selected node.
