Configuring the Block

Updated

A block consisting of 3 nodes can be setup to ensure that the correct nodes are identified and configured when the setup is run.

Before You Begin

Identify the Node Serial Number associated with the nodes in the block.

Procedure

Login to one of the nodes using the following default credentials:

Login: root

Password: cvadmin

Note: This password can be changed during setup.

  1. Navigate to the following folder:

    /opt/commvault/MediaAgent

  2. Create a block from one of the nodes using the following command:

    ./cvavahi.py set_blkid <block id> <node1 serial number> <node2 serial number> <node3 serial number>

    Where:

    <block id> is an unique, unused name for the block.

    <node1 serial number> <node2 serial number> <node3 serial number> are the serial numbers associated with the nodes.

    Example:

    ./cvavahi.py set_blkid My_New_Block XXXX123456 XXXX123457 XXXX123458

    This command should create the block. (No messages will be displayed if the block is successfully set.)

    You can verify whether the block is created using the following command:

    # cat /etc/avahi/services/cvlt.service | grep blkid

    You will see an output similar to the following:

    <txt-record>blkid=<block id></txt-record>
  3. Reboot the nodes.
