Deploying a Linux Access Node for Nutanix

You can deploy an AHV Linux access node using the QCOW2 template provided by Commvault. You can use the Linux access node to perform VM backup, Live Browse and File Recovery operations, with support for ext2, ext3, ext4, XFS, JFS, HFS and HFS Plus file systems (subvolumes). You can also browse VM data from a backup for the source VM.

Note

  • As needed, Commvault updates the QCOW2 template to include operating system updates and enhancements. To ensure that the access node contains all features and critical security vulnerability fixes, you must decommission the existing client and deploy the latest Access Node and MediaAgent QCOW2 template. You must also upgrade the CommServe server and Virtual Server Agent to the most recent Commvault service pack or install available HotFixes for the installed service pack.

  • You must decommission the existing client only if it was deployed in maintenance release of the respective Commvault service pack, prior to August 2024.

  • Starting 11.36 release, the template has the automatic OS updates feature enabled by default, which automatically installs all critical security vulnerability fixes without the need of decommissioning the client.

Before You Begin

  • Before creating the access node for Linux file restores, ensure that the CommServe server and Virtual Server Agent have the latest service pack updates.

  • To verify the supported Nutanix software versions, see System Requirements. For instructions, see Nutanix AHV System Requirements.

  • Ensure that the Cluster and container where you deploy the access node meets the following requirements:

    • 2 vCPUs

    • 4 GB of RAM

    • 80 GB disk

    • 1 NIC

  • The user name must have administrator permissions to create image.

  • The Linux access node supports live browse and restore of NTFS files from a Linux MediaAgent. For more information, see NTFS Live Browse for Restores Using a Linux MediaAgent.

  • Live recovery is only supported for recovery from backups using magnetic disk libraries, not from backups to tape libraries.

  • Live browse and file recovery operations are not supported for XFS realtime subvolumes.

  • The Linux access node supports NFS version 3 for guest file restores.

Note

To perform a live browse of files on RedHat Enterprise Linux or Oracle Linux 9.x VMs, you must deploy Commvault software Feature Release 36 or a corresponding recent version of the Access Node and MediaAgent QCOW2.

Procedure

  1. On the Cloud Services website, go to the Commvault Store and download the Nutanix access node Image with 11.36 n package for the installed service pack (for example, SP36) to a location that is accessible from the Nutanix AHV cluster.

  2. Go to https:// < cluster-IP-or-FQDN > :9440/console/#page/settings/acropolis_image, and then upload the image to the Nutanix AHV cluster.

    A new task is launched.

  3. Check whether the new task is complete at https:// < cluster-IP-or-FQDN > :9440/console/#page/tasks.

  4. Go to VMs page, click Create VM, and then use the following configuration:

    • 2 vCPUs

    • 4 GB of RAM

    • 80 GB disk

    • 1 NIC

  5. Add a disk and select option Clone from Image Service.

  6. Select Custom Script.

  7. In the Type Or Paste Script, the following parameters apply:

    • Parameters marked as required (Yes) must be defined for successful registration.

    • Optional parameters can be customized as needed for your network configuration.

      Parameter Description Required
      paramIsFBRMA Enables Full Backup Restore Media Agent mode. Set to True to enable. Yes
      paramNetworkGateway Hostname or FQDN of the CommServe (CS). Yes
      paramAuthCode Tenant authentication code for registration. Yes
      paramIpRoute Default IP route for the NIC (format: x.x.x.x/prefix). No
      paramTimezone Linux timezone name (case-sensitive). No
      paramTimeserver NTP server FQDN. No
      aaUseDHCP Specifies whether to use DHCP for network configuration (True or False). Yes
      abIP Static IPv4 address for the NIC (required only when DHCP is False). No
      acNetmask Static subnet mask for the NIC (required only when DHCP is False). No
      adGateway Static gateway for the NIC (required only when DHCP is False). No
      aeDNSSearch DNS search prefix. No
      afdns1 Primary DNS server (required only when DHCP is False). No
      agdns2 Secondary DNS server (required only when DHCP is False). No
      baClientName Client name (case-sensitive). Yes
      bbClientHostname Client hostname. No
      bcRootPassword Root password for the client. Yes
      bdClientGroup Client group name (case-sensitive). No
      beAutomaticOSUpdates Enables or disables automatic OS updates (True or False). No
      ccCSUsername CommServe username used for registration. Yes
      cdCSPassword CommServe password used for registration. Yes

      Note

      The user name must have both Global > Administrative Management and Commcell > Install Client permissions.

  8. Click Save.

    A new VM is launched and registered to the CommServe.
