Good day

    I strongly recommend using diffrent host names for diffrent IP's.

    Lot of IP's with same DNS name is on page 1, line 1 of my "do not do". 

    Slow responding netbackup is often related to DNS lookups not being answered or network connections not being accepted. Either way, becuase Netbackup relies on host based authentication, each diffrent IP must have its own host name.

      Hi Nicolai

      do you mean

      10.221.241.70   NRECNETBK111-1
      10.31.12.199  NRECNETBK111-2
      10.220.7.30  NRECNETBK111-3

      What about from client which is on different subent and different vlan ?

      what will be the output from client bpclntcmd -hn ? if i use different hostname ?

        "do you mean

        10.221.241.70   NRECNETBK111-1
        10.31.12.199  NRECNETBK111-2
        10.220.7.30  NRECNETBK111-3 "

        IMHO - yes.
        This is how I would do it:

        1. Ensure that each IP address linked to different hostnames
        2. Add SERVER entries for each hostname
        3. Confirm that media servers and client on each is configured for relevant hostname/IP/Server.
        4. 'bpclntcmd -self' should only show hostname NRECNETBK111 and primary IP.
        bpclntcmd will resolve each hostname and IP to one entry only.
        5. Add PREFERRED_NETWORK entries for each of the VLANs.

    Hello,

    Were you able to gather java logs or any network communication logs to confirm that java console is slow when using multiple vlan's...  ?

    Were you able to isolate the performance being better with reduced number of vlan's ?

    Is you master server a virtual machine where you have multiple vlan's set ?

    It usualy starts slowly but then works nice. Some of our customers have same configurations and same difficulties.

      Hi Mike

      i have 2 master servers each with morethan 12 Vlans.

      Master 2 is working fine but Master1 is bit slow.
