Upgrading Nodes in Clusters 26

3 Install Parallels Virtuozzo Containers 4.6 on the node. For detailed information on installing

Parallels Virtuozzo Containers 4.6, see the Parallels Virtuozzo Containers 4.6 Installation

Guide; for upgrade details, see the Upgrading from SWsoft Virtuozzo 3.0 Service Pack 1 (p. 7)

and Upgrading from Parallels Virtuozzo Containers 4.0 (p. 14) 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 not present in the list of process

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 gfs, gfs2, cman, and rgmanager services, and enable the

startup of the vz service:

# chkconfig gfs off

# chkconfig gfs2 off

# chkconfig rgmanager off

# chkconfig cman off

# chkconfig vz on

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

additionally disable the openais service:

# chkconfig openais off

If your data shared storage is located on an NFS volume, you do not need to disable the gfs

and gfs2 services.

4 Install Parallels Virtuozzo Containers 4.6 on the node:

a Use the --clustermode option when installing Parallels Virtuozzo Containers 4.6 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

a If you used the Parallels Infrastructure Manager application (renamed to Parallels

Virtual Automation in Parallels Virtuozzo Containers 4.6) for administering your cluster

nodes, you also need to upgrade this application. First of all, update Parallels

Infrastructure Manager to its latest version. When installing Parallels Virtuozzo

Containers 4.6, specify the --pva-agent option, for example:

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

agent"
