Using catalog backup and recovery to transfer NetBackup catalogs between UNIX or Linux master servers as part of a hardware refresh
- The version of NetBackup installed on the old and new hardware must be the same release update of NetBackup (e.g. if the old master server is running NetBackup 7.6.1, install NetBackup 7.6.1 on the new master server).
- The master server must not be a storage server for SharedDisk storage.
- The host name of the old and new hardware must be the same.
- The type and version of O/S on the new master server does not matter provided it supports the version of NetBackup used on the old master server. For example this procedure may be used to replace a Solaris 9 Sparc master server with a Solaris 10 X64 master server. However, use caution if any filesystem extended attributes were in use on the original master server. In such a case, it will likely be necessary that the new server be partitioned using the same filesystem type that existed on the old master server.
- Make a full catalog backup of the old master server and shut it down.
- Prepare the new master server using the same host name as the old master server (ensure that the conditions stated above are met). If the master server is also a storage server for AdvancedDisk volumes ensure that the volumes are presented to the same mount points on the new master server (i.e. /disk1 on the old master server must be mounted as /disk1 on the new master server). If the old master server has access to OpenStorage and PureDisk deduplication devices ensure that the new master server can access the same devices using the same storage server name.
- Install the same version of NetBackup on the new master as the version on the old master server (i.e. if the old master server is running NetBackup 7.6.1, install NetBackup 7.6.1 on the new master server).
- Restore the catalog backup created from the old master server to the new master server. Details of the catalog restore process can be found in the Disaster Recovery section of the NetBackup Troubleshooting Guide.
- Once the catalog has been restored confirm the basic operation of NetBackup by running test backup and restore jobs.
- If the master server is also a media server, run the device discovery wizard to update the locally presented devices and storage units.
- If the operating system has changed (for example from Solaris to AIX) run the command nbemmcmd -updatehost -machinename <master server name> -machinetype master -operatingsystem <new O/S>. Running this command updates the operating system field in the EMM master server record to reflect the new operating system. A list of valid operating systems can be found in the on-line help for the nbemmcmd -updatehost command.
