Re: Netbackup Appliance with vmware Error 23

Hi,

You may want to check all what is network.

the connection from your appliance (backup host) to the ESXs > telnet on port 902 with both (ip address and name) if the telnet with address ip is success and with name fails, then you may want to check your dns or just add the entry in hosts file).

one more thing, try to browse on your VM from the VMware policy, if you are able to do it then the communication between your master and the vmware side is Ok through 433 if its not, you may want to check that as well.

If you did all this and still have a problem, enable vxms logs on your appliance and launch a new backup test then share the logs.

Good luck.

Re: Netbackup Appliance with vmware Error 23

as @hha_mea Menctioned, checing the network connectivty between the backup and and ESXi host over the port 902 is the starting place.

you can do that with simple telnet command like "telnet exsihostname 902

Re: Netbackup Appliance with vmware Error 23

Thanks all.

I could resolve the issue.

Even all ports were open. I could find the issue at last.

Since the Vcenter is 5.1 and the server is 8.2 it had compatibility issue.

I installed a backup host on the vcenter with version 7.7.3 then backups ran smoothley.
