When you are sharing libraries across multiple DPM servers, they function as a single unit. If an upgrade is being performed on one server, all other servers stop working during the upgrade. The DPM server tape backups will fail for the upgraded DPM servers until all the servers are upgraded to DPM 2010 and library sharing is reconfigured.

For the purposes of this procedure, the DPM server, which is the library server, is referred to as the GDB. The DPM servers which act as the library clients are referred to as DCLi1, DCLi2, DCLi3.

To upgrade a DPM server that is using a shared library

  1. From the command prompt, type SetSharedDPMDatabase.exe-removedatabasesharing on the DCLi1 library client.

  2. Type AddLibraryServerForDPM.exe –dpmserverwithlibrary <FQDN of GDB> to remove the DPM server from the DCLi1 library client.

  3. Perform the DPM upgrade on the library client. For more information about Upgrading the DPM server using a remote instance of SQL Server 2008, see Upgrading to DPM 2010 using a Remote Instance of SQL Server. For more information about Upgrading the DPM server using a local instance of SQL Server 2008, see Upgrading to DPM 2010 using a Local Instance of SQL Server.

  4. Repeat Steps 1 through 3 for the DCLi2 and DCLi3 library clients.

  5. From the command prompt, type AddLibraryServerForDPM.exe – sharelibrarywithdpm <FQDN of  client> to remove all of the library clients on the GDB library server.

  6. Type SetSharedDPMDatabase.exe-removedatabasesharing on the GDB library server.

  7. Perform the DPM upgrade on the GDB library server.

  8. Reconfigure tape library sharing. For more information about reconfiguring the tape library, see Setting up Tape Library Sharing (http://go.microsoft.com/fwlink/?LinkId=165360).
