Upgrading Nodes in Clusters

2 Disable the startup of the rgmanager clustering service, and enable the startup of the vz

service:

# chkconfig rgmanager off

# chkconfig vz on

If you are upgrading a node running SUSE Linux Enterprise Server, you need to additionally

disable the openais service:

# chkconfig openais off

3 Install Parallels Virtuozzo Containers 4.7 on the node. For detailed information on installing

Parallels Virtuozzo Containers 4.7, see the Parallels Virtuozzo Containers 4.7 Installation Guide;

for upgrade details, see the Upgrading from SWsoft Virtuozzo 3.0 Service Pack 1 and

Upgrading from Parallels Virtuozzo Containers 4.0 and 4.6 (p. 8) chapters.

4 Once the installation is complete, restart the node, and wait for the Parallels Virtual Automation

application to get upgraded. To make sure that the Parallels Virtual Automation upgrade is

complete, check that the pva-setup process is absent from the list of processes running on

the node.

5 Enable the startup of the rgmanager service, and disable the startup of the vz, pvapp, and

pvaagentd services:

# chkconfig rgmanager on

# chkconfig vz off

# chkconfig pvapp off

# chkconfig pvaagentd off

Upgrading Passive Nodes in the Cluster

Now that you have upgraded all active nodes in the cluster, you can proceed with upgrading

passive nodes. To upgrade a passive node, do the following:

1 Make sure that the node does not have a /vz partition mounted. If it does, unmount the

partition.

2 Comment the /vz entry in the /etc/fstab file.

3 Disable the startup of the cman and rgmanager services, and enable the startup of the vz

service:

4 Make sure that all NFS-related services are enabled on the node:

# chkconfig rgmanager off

# chkconfig cman off

# chkconfig vz on

5 Install Parallels Virtuozzo Containers 4.7 on the node:

a Use the --clustermode option when installing Parallels Virtuozzo Containers 4.7 on

passive nodes:

• If you use the vzautoinstall utility, run this command:

# ./vzinstall-linux-x86_64.bin install --vzinstall-opts "--clustermode"

• If you use the install utility, run this command:

# ./install --clustermode
