Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

For private disk groups, determine and note down the hosts on which the

disk groups are imported.

See “Determining the nodes on which disk groups are online” on page 201.

For shared disk groups, run the following command on any node in the CVM

cluster:

# vxdctl -c mode

Note the master and record it for future use.

Determining the nodes on which disk groups are online

For private disk groups, determine and note down the hosts on which the disk

groups containing RVG resources are imported. This information is required for

restoring the configuration after the upgrade.

To determine the online disk groups

On any node in the cluster, list the disk groups in your configuration, and

note down the disk group names listed in the output for future use:

# hares -display -type RVG -attribute DiskGroup

Note: Write down the list of the disk groups that are under VCS control.

For each disk group listed in the output in step 1, list its corresponding disk

group resource name:

# hares -list DiskGroup=diskgroup Type=DiskGroup

For each disk group resource name listed in the output in step 2, get and note

down the node on which the disk group is imported by typing the following

command:

# hares -display dg_resname -attribute State

The output displays the disk groups that are under VCS control and nodes

on which the disk groups are imported.

Preparing for the upgrade when VCS agents are configured

If you have configured the VCS agents, it is recommended that you take backups

of the configuration files, such as main.cf and types.cf, which are present in

the /etc/VRTSvcs/conf/config directory.
