  • Replace failed media server hardware
    Posted: 08-16-2010, 10:17 PM

    Hi,

    I have a windows 2003 server mm1 which is:
    . media server with tape libraries and magnetic libraries (disk)
    . Exchange  Compliance Archiver agent
    . Exchange Mailbox agent
    . Exchange Mailbox Archiver agent
    . Exchange Public Folder agent
    . File System Agent

    The hardware on mm1 is failing.

    Questions:
    (A) Is the best way of replacing the hardware:

    1. Install Windows 2003 on new server with a name of mm1
    2. Deconfigure client mm1 in Commvault (Just at the client level NOT agent level)
    3. Shutdown old server mm1
    4. Power up new server mm1
    5. Install
    . media server software which should install Base software and Filesystem agent
    . Exchange  Compliance Archiver agent
    . Exchange Mailbox agent
    . Exchange Mailbox Archiver agent
    . Exchange Public Folder agent

    Is this correct?

    (B) I understand that the old configuration including storage policy, library,
    Exchange agent definition will still be there. Is this correct?

    (C) I may need to do a "Detect" as some of the tape hardware addresses may of changed.
    Is this correct?

    (D) I understamd that all the old backups are still available. Is this correct?

    Thanks for any help.

    For the media agent I would just follow the directions for Upgrading the OS on a media agent. While you are not changing the OS the same directions apply.

    As long as you do not rename the machine or change the IP there should not be a issue. Just remove the steps on upgrading the OS.

     

    MediaAgent - Upgrade the Operating System

    Use the following procedure to upgrade or fully replace any Operating System.

    Before You Begin

    The following instructions apply only if it is required for the computer you are upgrading.

    • From the CommCell Console, kill all jobs that are running, waiting, pending, or stopped.
    • As a precautionary measure, perform a Disaster Recovery Backup.
    • Unload all tapes from all drives in every library attached to the computer you are upgrading.
    • From the Activity Control tab of the CommCell properties in the CommCell Console, disable data protection and data recovery operations.
    • From the Service Control Manager window, stop all services.

    To perform an operating system upgrade on a MediaAgent computer:

    1. Power off all libraries connected to this MediaAgent.
    2. Uninstall the MediaAgent and any File System iDataAgent (if present).
        WARNING: Do not delete any Storage Policies or Deconfigure any libraries, as this will cause data loss.
    3. Upgrade/replace the operating system.
    4. Power-on the library.
    5. Detect the connected devices.
    6. For Windows 2000 or 2003, from the Services window, disable the RSM service.
    7. Disable the media changer for the library in the Windows Device Manager.
    8. Install the MediaAgent and all updates, as well as any File System iDataAgent (if desired).
    9. If services are not already started, restart services from the Service Control Manager window.
    10. From the Library and Drive Configuration window, confirm that all libraries and drives remain configured and detected. If a library or drive is configured, but not detected, detect devices again using the Library and Drive Configuration window. For more information on detecting devices, see Detect Devices.
    11. From the Activity Control tab of the CommCell properties in the CommCell Console, enable data protection and data recovery operations.

    You have completed the operating system upgrade procedure for a MediaAgent computer.

    The easiest way to accomplish this is

    1. Leave all agents installed on old machine and shutdown.

    2. Install new machine with OS and name the same.

    3. Install commvault agents specifying the same client name and host name.

     

    This will keep all the backup history and keep all the settings in the commcell.  The new install will not consume any additional licenses as the commserve thinks it is already installed.

     

    Let me know if you have any questions.
