Prerequisites
Veritas Cluster Server is installed and configured.
Veritas NetBackup is installed and configured on the Veritas Infoscale Availability (VCS) in a clustered mode.
Veritas NetBackup data volume resides on a volume shared across cluster nodes.
A shared storage of sufficient capacity is configured across the cluster nodes. The size of the shared storage depends on the data to be collected. Refer to IT Analytics Certified Configuration Guide for recommended storage size.
The shared storage can be either a Veritas Infoscale Volume Manager (VxVM) or a disk. If the storage is under VxVM, ensure that Disk group and Volumes are already created.
Ensure that file system is created on the shared storage.
Ensure that the file system is mounted on a mount point. The Data Collector will be installed on this file system.
Passwordless SSH for root user must be configured among the cluster nodes for installation and upgrade to work properly.
