Setting Up a Block

Before setting up the Commvault HyperScale Appliance, setup a block consisting of 3 nodes to ensure that the correct nodes are identified and configured when the setup is run.

Procedure

  1. Power on the nodes.

    Recommended: Power on 3 un-configured nodes at a time. (If you have more than 3 un-configured nodes, you can add the other nodes later.)

  2. Note down the serial number of the node displayed in the prompt as shown in the following sample image:

  3. Navigate to the following folder:

    /opt/commvault/MediaAgent

  4. Identify the network interfaces in your hardware using the ifconfig command.

    A sample output of the command is shown below:

  5. Create a block from one of the nodes.

    Depending on the number of network interfaces in your hardware, use one of the following commands.

    • If you have 2 - 10 GB network interfaces, (1 for Data Protection and 1 for Storage Pool), then setup the block a follows:

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

      Example:

      ./cvavahi.py set_blkid My_New_Block ymbq001141 ymbq001142 ymbq001143

    • If you have 4 - 10 GB network interfaces, (2 for Data Protection and 2 for Storage Pool), and to bond the interfaces together for redundancy (or failover), setup the block as follows:

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

      Example:

      ./cvavahi.py set_blkid My_New_Block ymbq001141 ymbq001142 ymbq001143 active-backup

    • If you have 4 - 10 GB network interfaces, (2 for Data Protection and 2 for Storage Pool), and to bond the interfaces together for performance (or link aggregation), setup the block as follows:

      ./cvavahi.py set_blkid <block id> <node1 serial number> <node2 serial number> <node3 serial number> 802.3ad

      Example:

      ./cvavahi.py set_blkid My_New_Block ymbq001141 ymbq001142 ymbq001143 802.3ad

    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 noted down in step2.
