Netbackup 8.1 client and Windows failover cluster

Hi all, I'm trying to install and configure new Windows filers failover cluster on Windows 2012 R2. I've installed client on both Windows server. Access them from admin console is OK. When I want to add virtual name of this cluster on policy, I've received this error : "Unable to connect to Netbackup host" When I look in client properties, I've see that : "The vnetd proxy encountered an error". I've read few guide, but I've not see any recommandations about this trivial configuration. Any idea ? Thanks

    So...

    I've added my virtual name on each host mapped host name and communication is OK now.
    I've not use "Add Shared or cluster mappings"...

    Have you tested forward and reverse name lookup at OS-level for the Cluster Group virtual hostname? 
    e.g. nslookup, ping, etc from the master/media server.

    Try NBU lookup and port connection from cmd on NBU master and/or media server:

    bptestbpcd -client <virt-name> -debug -verbose

      Thanks Marianne.
      Below the end of result of this command with virtual name :

      there is a link with certificate ? In Security Management\Host Management, i've see my 2 clients.

        Hello,

        yes in Security Management\Host Management, you should add virtual names as Mapped Host Names fro both physical nodes.

        Add As Cluster Mappings, if it wont work, then Add as Host Mappings

        Regards

        Michal

        Nope, I think there is a mistake with certificate or anything else about security.

    Another thought:

    Since this is version 8.1 - it may have something to do with security certificates...

    Hopefully someone with more 8.1 experience will reply soon.

    Have you set these machines up as an app_cluster in Netbackup? 

    On the master server:

    nbemmcmd -addhost -machinename appcluster.name -machinetype app_cluster

    nbemmcmd -updatehost -add_server_to_app_cluster -machinename machinename.host1 -machinetype media -clustername appcluster.name -netbackupversion 8.0 -masterserver master.server

    nbemmcmd -updatehost -add_server_to_app_cluster -machinename machinename.host2 -machinetype media -clustername appcluster.name -netbackupversion 8.0 -masterserver master.server

      Hello Mystre316,

      these commands are for NetBackup servers, not clients. IMHO, the issue has been resolved by Host Mappings.

        Of course, I've resolved my problem with adding virtual name to host mappings on my two servers.

        What the objective of "add shared or cluster mappings" option ?
