Requirements for Windows cluster upgrades

In addition to the normal server requirements, NetBackup cluster upgrades require special considerations.

The following describes the guidelines for NetBackup cluster upgrades on Windows systems:

Table: Windows cluster requirements for installation and upgrade

Item

Requirement

Server operating system

Make sure that you have applied the most current operating system patches and updates, including any security updates. If you are not certain that your operating system is current, contact your operating system vendor and request the latest patches and upgrades.

For a complete list of compatible operating systems, refer to the Software Compatibility List (SCL) at the following website:

  • http://www.netbackup.com/compatibility

  • https://sort.veritas.com/netbackup

Privileges

To perform clustered installations, you must have administrator privileges on all of the remote nodes in the cluster. Keep a record of all nodes in the cluster and what software exists on each node.

NetBackup virtual name and IP address

Have the virtual name and IP address for NetBackup available. You must provide this information during installation.

Operating system on nodes

All clustered nodes must use the same operating system version, service pack level, and NetBackup version. You cannot run mixed server versions in a clustered environment.

Cluster support changes for media servers

Clustered media servers are not supported.

Windows Server Failover Clusters (WSFC)

Make sure that you have applied the most current operating system patches and updates, including any security updates. If you are not certain that your operating system is current, contact your operating system vendor and request the latest patches and upgrades.

For a complete list of compatible operating systems, refer to the Software Compatibility List (SCL) at the following website:

  • http://www.netbackup.com/compatibility

  • https://sort.veritas.com/netbackup

  • Before you begin the install or the upgrade, take all NetBackup resources offline except for the shared disk resource, the virtual IP, and the virtual name.

  • Install or upgrade NetBackup from the active node (the node with the shared disk resource, virtual IP, and virtual name).

  • The computer or the host names cannot be longer than 15 characters.

Cluster Server (VCS) clusters

  • All NetBackup disk resources must be configured in Cohesity Enterprise Administrator (VEA) before you install NetBackup.

  • You must take the VCS NetBackup resource offline before you begin the install or the upgrade.

    Note:

    Make sure that shared disk and IP resources are online during the install or the upgrade on active node.

Cluster node device configuration and upgrades

When you upgrade clusters, the ltid and the robotic daemons retrieve the device configuration for a particular cluster node from the NetBackup database. The cluster node name (provided by gethostname) stores or retrieves the device configuration in the NetBackup database. The cluster node name is used when any updates are made to the device configuration, including when ltid updates the drive status. The cluster node name is only used to indicate where a device is connected. The NetBackup virtual name is employed for other uses, such as the robot control host.
