Veritas NetBackup™ Appliance Decommissioning and Reconfiguration Guide

Performing pre-installation checks for role compatibility and version compatibility

From NetBackup Appliance 5.0, checks have been added to the role configuration process for role compatibility and version compatibility. When a NetBackup Appliance is re-imaged and role configuration is performed, if the storage setting is not erased using the Support > Storage Reset or Support > FactoryReset command, the following checks are performed before role configuration is done.

Checking for role compatibility

The existing storage setting is checked to verify if the previous role matches the current role. If the roles are not exactly the same, a warning message is displayed and the role configuration process is stopped. For example, if an appliance was installed and configured as a primary server, and if you try to re-image it and configure it as a media server, role configuration is stopped.

Checking for version compatibility

The appliance records and upgrades the Appliance version on the external disk. If you try to re-image an appliance with a version later than the current release version, a version check is triggered. You can re-image the appliance and reconfigure the role only if the appliance version remains the same. If the previous version and current version do not match, the role configuration process will be stopped.
