Installation prerequisites for NetBackup on PCS Linux
The following requirements must be met before you install and configure a NetBackup on Pacemaker cluster:
Verify that Red Hat Pacemaker (PCS) cluster is correctly configured on Linux which is up and running.
Verify that no PCS resource group and resource exist with the same name as the one you intend to use for NetBackup.
Make sure STONITH is disabled in Pacemaker Cluster Configuration as it is not supported for fresh install.
Make sure that the shared disk is configured and accessible to all cluster nodes where you want to install NetBackup. Also, verify that you can mount the disk.
Verify that you have an IP address (virtual IP) and a host name (virtual name) to assign to the NetBackup resource in PCS. Use these only for the NetBackup resource in PCS. Also, ping the IP address and verify that the IP address is not plumbed.
Make sure that each node in the cluster, where you want to install NetBackup, is Secure Sell Protocol (SSH) equivalent. As the root user you must be able to perform a remote sign in to each node in the cluster without entering a password. This configuration is only necessary for installation and configuration of the NetBackup server and any NetBackup options.
Verify that you have the current NetBackup Primary Server version installation program and a valid license key.
