Setting Up HyperScale Storage Nodes in Environments with DHCP

In environments with a DHCP server, all the HyperScale nodes can be setup from one of the nodes. Note that DHCP is used only to setup the nodes and subsequently, once the nodes are setup, the nodes use a static IP for network communication.

Before You Begin

• Verify that the hardware meets the specifications provided in HyperScale Reference Architecture - Architectural Overview.

• The node has the Solid State Drives (SSD). For more information about the SSD specifications see, Hardware Specifications for Deduplication Mode.

• Use the data collected in the HyperScale Reference Architecture - Preinstallation Checklist to setup the nodes.

• For creating or scaling out the HyperScale Storage Pool, we recommend to use the same size disk.

• It is recommended that special characters are not used in HyperScale Storage Pool names.

• To achieve disk level redundancy and for better performance, we recommend to have Non-RAID on spindle disks for storage. However, if there is already a hardware RAID card in the node, you must bypass the RAID card and configure them as independent physical disks.

• Ensure that 10 GigE network ports are used for HyperScale Storage Pool communications. (Separate 10 GigE network ports for Data Protection network and StoragePool network.)

• Each node must have two network ports.

  • One network port is used for Commvault communication and the IP address associated with the network port must resolve to the host name used for Commvault communication.

  • The other network port is used for storage pool communication and the IP address associated with the network port must resolve to the host name used for Commvault communication with sds suffix.

  • For example: If the IP address associated with network port used for Commvault communication resolves to hostname scaleout1, the IP address associated with network port used for storage pool communication will resolve to scaleout1sds.

• Ensure that you have separate subnets for the Data Protection network and for the StoragePool network.

Procedure

1. Download the latest ISO (HyperScale 1.5) as follows:

   1. Open a Web browser, and then go to Commvault Store.

   2. Download the latest ISO.

2. Boot node 1 with the downloaded DVD.

   After the boot sequence, the Node Configuration page will be displayed.

3. On the Node Configuration page, proceed to the next page.

   The IP address associated with the node will be displayed under Network Interface.

   Tip

   Note down this IP address.

4. Boot node 2 with the downloaded DVD and note down the IP address associated with the node displayed under Network Interface.

5. Boot node 3 with the downloaded DVD.

6. On the Node Configuration page, select the following options, and then proceed to the next page.

   1. Choose the Control node option.

   2. Choose the Mulit Node Installation option.

   A list of discovered hosts will be displayed in the Hyperscale Cluster Nodes Setup page.

7. From the Hyperscale Cluster Nodes Setup page, select the IP addresses associated with node 1 and node 2, that was noted in steps 3 and 4, and then proceed to the next page.

   Note

   Node 3 will be used to automatically setup nodes 1 and 2.

8. On the System Drives page, select the operating system drive, and then proceed to the next page.

   Typically the operating system drive would be the SATA SSD drive.

9. On the Metadata Drives page, select the metadata drive for storing the Deduplication Database (DDB) and the Index Cache, and then proceed to the next page.

   Typically the metadata drive would be the Flash/NVMe/SSD drive.

10. On the Data Drives page, select the drives for configuring the storage pool, and then proceed to the next page.

11. On the Configuration Summary page, verify the information, and then proceed to the next page.

    The program installs the software and displays the progress in the Installation Status page.

    This process will take some time to complete.

12. In the Installation Status page, click Finish to complete the installation.

    The nodes will be rebooted.

13. After the reboot navigate to the following folder:

    cd /opt/commvault/MediaAgent

14. Execute the following command:

    ./setupsds

15. When prompted, provide the MediaAgent node name details as follows:

    1. In the Hostname of the server box, type the MediaAgent node name.

       Tip

       Use Fully Qualified Domain Names (FQDN) for the hostname to avoid name resolution issues.

    2. Provide a password for the node

16. When prompted with the following message in the wizard, select Setup.

    Please select whether network needs to be configured.
     Setup    Skip

    If the network is already configured or if Static IP is used, select Skip. Proceed to Step 20.

17. Select the appropriate mode for network bonding and then select OK.

    Mode0, Mode1 and Mode4 are supported.

    Mode1 or Mode4 is recommended.

18. Select a network interface for Data protection network and then select OK.

19. Enter the network configuration details for the selected interface, like IP address, Subnet Mask, Gateway and DNS Server Name, with appropriate values.

20. Select a network interface for StoragePool Network and then select OK.

21. Enter the network configuration details for the selected interface, like IP address, Subnet Mask, Gateway and DNS Server Name, with appropriate values. (Gateway and DNS Server Name is optional.)

22. You will be prompted to register with the CommServe host.

23. Type the CommServe host credentials to register the MediaAgent nodes with the CommServe host:

    Note

    If the CommServe is located behind a firewall, you must perform additional steps to connect to the CommServe. For more information, see Connecting to a CommServe behind a Firewall During Setup.

    1. In the CommServe hostname box type the CommServe host name.

    2. In the CommServe User name box type the CommCell login details.

    3. In the CommServe password box, type the CommCell password.

    4. Click OK.

This completes the setup.

What To Do Next

• Verify that all the MediaAgents, which will become a part of the StoragePool, are able to resolve the IP address associated with data protection network and the StoragePool network.

• Create a HyperScale Storage Pool in the CommServe using the nodes. For more information see, Creating a HyperScale Storage Pool.

• If a PXE server was used to install and setup the HyperScale Storage Nodes, make sure to disconnect the PXE network from the nodes.
