    With the help of davidmoline , i found the problem.

    1- my NBU Servers had 2 IP addresses, one was in ESXi subnet, and another was in Backup subnet - Esxi and vcenter were resolving NBU servers to their backup subnet. adding nbu servers with esxi subnet IPs solved some of my problems.

    2- CDP Gateway knew itself using Backup subnet IP, however adding CDP gateway server name and its second ip (ESXi subnet) to its host file did not solve the problem. even after clearing the OS and NBU cache.

    3- but restarting both master and cdp gw did!

    Thank you davidmoline

Hi mehrdad64 

Does the CDP gateway have multiple IP addresses? If so ensure the nbcctb process is listening on the correct IP address that both the primary and ESXi servers resolve the gateway to.

Another possibility is the VM was cloned and the BIOS UUID was not changed causing a possible problem if the original VM is also being protected by CDP (I do no think this would be the case here though). 

If none of the above apply, then I'd suggest logging a support case 

Cheers
David

Hi davidmoline 

thanks for your help, yes indeed both of my servers (Primary and CDP) have 2 IP addresses, after reading you replay i corrected dns records for all esxi hosts and vcenter. now all hosts and vcenter are resolving cdp and primary using correct ip address (192.168.110.xx same network as hosts) , although primary and cdp resolving each other on a different subnet (10.10.10.xx).

How can i check that , i couldnt find anyway to find the ip binding of nbcctd proccess.

thanks

    Hi mehrdad64 

    Either use the lsof command with PID of the nbcctb command, or use the netstat command and look for port 33056. 

    Cheers

      its running and listening on 0.0.0.0 so i guess its binding to all the ip addresses.

      do you know where can find more details about the cdp process ,maybe a log file(other than nbcctd) in CDP or vCenter.

      thanks!

        hi mehrdad64 

        The process is listening on the local address xxx-bkup-ii.domain.net as per the netstat and lsof output (the 0.0.0.0:* is the remote address). The local address is xxx-bkup-ii.domain.net:33056.

        I'd review the troubleshooting section in the VMware WebUI admin guide and see if that helps. If all else fails, log a support call.

    i added host file for primary and cdp server so that now they are all resolve in the same subnet with esxi and vcenter. (192.168.10.xx) after that did a clear host cache but still getting the same error "IOTapping not started. No PIT available."

    how can i test veritas vtstap I/O filter , maybe vstap is not working correctly.
