NBU Master Media Server Merging


Dear All,

i have one NBU Master/Media/Emm 6.5.4 on SUN Sparc, Solaris 5.10

i want to add a Media Server to the existing environment?

i was looking in to the other forums related to this? but got no specific solution/method ?

kindly correct me, if i am wrong?
what i got from the previous forums, on the other machine which i want to make a Media Server , i do a ./install of NBU setup and continue with that.

    Installation of media server was incorrect:

    Would you like to use "ddbbackup" as the configured
    name of the NetBackup server? [y,n] (y) n

    Enter the name of the NetBackup server: pdbbackup

    Is pdbbackup the master server? [y,n] (y)

    The 1st answer should have been Y
    Would you like to use "ddbbackup" as the configured
    name of the NetBackup server? [y,n] (y)  y

    The question after the y answer would have been:
    Is ddbbackup the master server? [y,n] (y)  n

    It would then prompt you for the name of the master server...

    You might be able to fix everything by editing bp.conf on the media server.

    The entries should look like this:

    SERVER = pdbbackup
    SERVER = ddbbackup
    CLIENT_NAME = ddbbackup

    Also check bp.conf entries on master. Should look like this:

    SERVER = pdbbackup
    SERVER = ddbbackup
    CLIENT_NAME = pdbbackup


    The fact that you manually added SERVER entry to master's bp.conf and restarted NBU was enough. The nbemmcmd command can be used in a 24x7 environment where you cannot stop/start NBU on the master.

    Restart NBU on Master and Media after confirming that all bp.conf entries are correct.

    Also verify on media server that emm server entry is correct (set to master server):
    /usr/openv/volmgr/bin/vmglob -get_gdbhost

    Did you add the new media server as SERVER to the client that you are backing up?
    Did you add the new media server to /etc/hosts on the client?
    Can the client resolve the media server's IP address back to the server name?

    Create bpcd log on client.
    From media server, test connectivity using :
    bptestbpcd -client <client_name>

    Check bpcd log for incoming connection from media server IP address.
    Next you will see the client trying to resolve IP address to a hostname.
    Once a hostname is found for the incoming address, NBU compares the hostname with SERVER entries in it's own bp.conf. If that process is unsuccessful, you see status 59.
    (Detailed explanation of status 59 in NetBackup Troubleshooting Guide as well as Troubleshooter in Activity Monitor)

    Dear,

    i had tried lot of tech notes, then i did one thing myself to add entry of Media Server in the bp.conf file.

    in Windows,

    HKEY_LOCAL_MACHINE\Software\VERITAS\NetBackup\CurrentVersion\Config\Server
    HKEY_LOCAL_MACHINE\Software\VERITAS\NetBackup\CurrentVersion\Config\Client_Name

    in Unix clients,
    /usr/openv/netbackup/bp.conf

    i used the available_storage of Media Server
    then it backed up sucessfully, and restoring. (confirmed it by looking the disk space of Media Server) but restoring only on one condition.
    in NBU console, --> backup archive and restore ---> Server use for backup and restore (pdbbackup)

    when i provide pdbabckup it restores sucessfully,  if i use ddbackup. it fails by "cannot connect on socket"error 25.

    is Media Server working well, or not ? or does it restores filesystem like this ?

    Restore GUI is not very informative about the Server entry.
    The Server name specified in Restore GUI must be the name of the server where the images database can be found, which is ALWAYS the master. The reason why you have the option of changing the Server name in the GUI, is for systems like my own desktop where I can connect to both our own in-house master as well as my lab master.

    The Master server will find the image to restore from and send the restore request to the media server that performed the backup.

    thats Kool.... so my file system backup/restores are sucesfull.

    i would also perform a NBU BMR using Media Server as well.

    one quick question. as i have only installed these 3 on media Server.
            NB_6.5.4 *
            NB_CLT_6.5.4 *
            NB_JAV_6.5.4 * 

    for doing a BMR of linux or windows.... do i need to install BMR on media Server ? or  Master would provide this functionality ?

    Glad to hear that your media server is working fine!!
    There are 3 BMR components:
    BMR master - can only go on master server and stores BMR backup components as part of EMM database.
    BMR boot server - you need one per O/S environvent (e.g, one Solaris boot server for Solaris Clients, one Linux Boot Server for Linux clients, one Windows, etc). Boot server can be installed on a media server or client.
    BMR client - software installed with normal client & media server software.

    In other words, if you want to make the new media server a BMR boot server, you need to install that software on it.Otherwise nothing else needed.
    You also only need database agents on the media server if there is a database installed on that particular media server and you want to use the agent to do a local hot database backup.

    Rather than manually editing the client's registry to add the new media server, you can do this using the Admin Console or JAVA Console.

    Click Hosts > Clients, then double click the client. Under the Servers tab, you can click the Add button to add the new media server to the client's configuration.

    kindly correct me if i am wrong ....

    --> i did a BMR restore from the Storage of Master Server(pdbabckup) sucessfully.

    After the BMR, system was up, i took a full BMR backup on the Storage of Media Server.

    --> Again performed a BMR, without any prompting it has restored from the Storage of Media Server.

    i think, while performing BMR, there is no need to add any package of BMR to Media Server. Master provides this functionality.

    Correct.
    If you don't need to config the media server as BBS (already done on your master), there is no need for any additional software on your new media server.
