About disaster recovery requirements
Veritas strongly recommends that during NetBackup installation in a disaster recovery mode after a disaster, you use the same master server name that is available in the disaster recovery email.
Note:
Certificates for active and inactive nodes are not recovered during catalog recovery. Therefore, you must manually deploy certificates on all cluster nodes using a reissue token after you install NetBackup in a disaster recovery mode.
See Generating a certificate on a clustered master server after disaster recovery installation.
For a successful disaster recovery in all environments, you must know:
The location of the disaster recovery package.
The passphrase for that specific disaster recovery package.
If the passphrase is lost, refer to the following article to get the host identity back.

Note:
Be aware that NetBackup does not support push, remote, or silent installation for the disaster recovery of master servers. Exception: NetBackup supports these installation methods for hosts in a NetBackup master server cluster.
