7. Run the sgupdate script, and follow the instructions provided in the install file to install the

6.13 Performing offline upgrade from A.11.18.X to A.11.20.20

The following procedure describes how to perform offline rolling upgrade from A.11.18.X to

A.11.20.20:

1. Halt the cluster.

For example, #cmhaltcl -f

2. Select a node you want to upgrade and uninstall pidentd rpm.

CAUTION: Serviceguard commands will not work unless step 4 is complete. You cannot

change the cluster configuration files until the process of upgrade is complete on all nodes.

Note: This step is applicable only on Red Hat Enterprise Linux.

#rpm -e --nodeps pidentd-3.0.19-0

3. Install authd rpm from distro.

#rpm -i <authd rpm>

Note: This step is applicable only on Red Hat Enterprise Linux.

4. Upgrade node1 to A.11.20.00 on Red Hat Enterprise Linux and A.11.20.10 on SUSE Linux

Enterprise Server.

The following examples show only the Serviceguard rpm. Generally, you also need to install

the following:

• cmsnmpd

• sgproviders

• serviceguard-xdc (on SUSE Linux Enterprise Server only)

For example, Serviceguard rpm for Red Hat 5 x86_64

#rpm –Uvh serviceguard-A.11.20.00-0.rhel5.x86_64.rpm

6. Run the sgupdate script and follow the instructions provided in the install file to install
