Manually Adding Volumes to the Monitored Volumes List

1. Log on to the client computer.

2. Open the command prompt, and then navigate to the Base folder of the Commvault installation directory:

    
   Commvault_Installation_Directory/Base

3. Type the following command:

    
   DcClient -monitor mount_path

   where: <mount_path> is the volume that you want to add to the monitoring list.

On a Cluster Setup:

Optimized Scan is supported only with active-passive cluster configurations.

• To list the volumes for the virtual client, type the command:

   
  DcClient -cluster vollist virtual_client_name

• To store the volume list for the virtual client, type the command:

   
  DcClient -cluster volcreate virtual_client_name vol 1, vol 2,...vol n

• To configure failovers:

  The shared volumes need to be added to the Monitored Volumes list on the active node using the DcClient -cluster volcreate command. Centralized Optimized Scan database is not supported for failovers. Even if you configure a centralized database for volumes that need failover capability, you must relocate the database to the root of the volume.

  The root (/) and the volumes that contain job results, tmp, and var (which contains Commvault log files) folders are not monitored by Optimized Scan.

A failure of any Agent software on the active node in a UNIX cluster will not cause a failover to be initiated.

The cvclusternotify script should be added as part of the normal cluster startup/shutdown procedure. The script is provided as a generic template, and it must be run at the beginning of node shutdown and at the end of new active node startup before any I/O or application starts on the cluster volumes. In both cases, data protection services must be up and running.

Run the following command to notify Commvault that the specified "Cluster Group" is going up or down because of a cluster failover:

Usage:

 
cvclusternotify -inst InstanceName -cn ClientName -start | -shutdown

Where:

• cvclusternotify is the script that notifies the Commvault software about cluster failovers.

• -inst specifies the name of the Commvault instance on which you want to run the script. If you have a single instance, specify Instance001.

• -cn is the name of the cluster group client.

Example:

For a two-node cluster, if the cluster group client name is "ClusterGroup1" and the application instance is "Instance001", run the following command:

• To shutdown:

  cvclusternotify -inst Instance001 -cn "ClusterGroup1" -shutdown

• To start up:

  cvclusternotify -inst Instance001 -cn "ClusterGroup1" -start
