Netbackup 10-CDP Status: 4207 4726

hi guys , 

im using Netbackup 10.1.1 -Primary server is installed on Suse EL 15 and Media server and CDP gateway are installed on RHEL 8.4

for last couple of days i've been trying to do CDP backups with no luck!

I used many configurations and changed a lot of things (standalone CDP gateway, Media server + Gateway...) and double-checked prerequisites multiple times, but no matter what CDP not working.

its important to note that VM's resides on VMWare vSAN , vCenter and ESXI  hosts version is 7.0.3 f

any help would be appreciated.

this is the error im getting :

    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
