Instant Recovery failed with 'socket open failed (21)' error message

Hello :)

I am working on IR_VMware feature with NBU 8.0
My Environment is:
Master Server: Windows 2012 R2
Media Server : HPUX host
Client Server : RHEL VM
VMware ESXi server version : 6.5


Before starting IR, I have renamed VM and Powered off in ESXi server.

I have backed up RHEL VM successfully. while performing Instant Recovery I am facing "socket open failed (21)" error.

For restore I am executing following command on NBU Master (windows host) host.

nbrestorevm -vmw -ir_activate -C RHEL_VM -backupid RHEL_VM_1000001836 -temp_location ABC<created NFS datastore on ESXi server>

    Did you configure a restore host that is not your HP-UX media server?

    The restore host can be on Windows or Linux.

    ■ For a restore host that is separate from the NetBackup master server or media server: You must add the restore host to the list of servers that can access the master server.

    I believe you are using the HP-UX which is not supported.  Might be easier if you made the Windows Master server the Backup Host and the Media Server for quicker IR configuration.

      Ensuring that the Windows Master Server is selected as Restore Host is important - similar to your post of a week ago.

      Before we get to the Restore Host - have you gone through the other requirements (as per the manual)?
      e.g. NFS on ESX server, NFS on the Restore Host and media server (NFS should be fine on Unix media server).

      The thing that worries me is this requirement:

      The NetBackup media server platform must support Granular Recovery
      Technology. See the NetBackup Enterprise Server and Server OS Software
      Compatibility List

      My problem is that I cannot find this information in the SCL. 
      Maybe eduncan can point us in the right direction?

        Media Server : HPUX host

        my restore host is RHEL VM.

        I have restarted NFS services on all hosts/servers.
        Previously I tried GRT with HPUX (i.e. media server) & it worked.

    Is HPUX backup host supported one for vmware? I doubt

    All 64 bit only: 
    Windows Server 2012 R2, 2012, 2008 R2 
    Red Hat Enterprise Linux (RHEL) 7.0, 6.6 
    NetBackup Appliance 3.0 
    SUSE Linux Enterprise Server (SLES) 12, 11.3

      Steps followed before restore:

      1.Created Virtual Server Machine (i.e. added Vsphare Center as VSM),
      2.Created Storage Server,Disk Pool, Storage unit (using StoreOnce Catalyst Store)
      3.Created VMware Policy
      4. backed up VM (RHEL) using VMware policy.
      5.Renamed VM in ESXi server.
      6.Powered off VM
      7.Created temporary NFS datastore for restore.
      8.executed restore command.

        There is a whole list of steps and pre-reqs that you have missed.

        Please see this topic in NBU for VMware manual:

    Hi,

    As was mentioned before is very important check all requirements for instant recovery for VMware, did you do?

    Other think, I found this TB below, and there is a similar problem to you, did you already check?

    Look

    TCP port 7394 (nbfsd) and 111 (portmap) from the target ESX server to the media server was not open.

     NetBackup Vmware Instant Recovery "Failed to export a backup image on the media server" - socket open failed 21 - https://www.veritas.com/support/en_US/article.000115596
