Did you have any firewall rules configured for the old IP addresses that you need to update?

Can you ping the client? If that fails try a traceroute to the client to see if it stops at any network hops.

Can you telnet clientname bpcd ?

Did you restart the Master server or run: bpclntcmd -clear_host_cache ?

On the clients run Netbackup command : bpclntcmd -clear_host_cache

On windows also run command : ipconfig /flushdns

Re-try backup

Best Regards

Did you shutdown NBU before changing IP? Was server rebooted, DNS cache, OS host cache and NBU host cache refreshed? Have you tested forward and reverse name lookup in all directions using bpclntcmd command with -hn and -ip options?

Dears All,

First of all many thanks for your swift response.

Kindly note NBU was shutdown, the server was restarted and clear cache command was run and refreshed, beside I've run bpclntcmd and got response the servers can ping from each side from client side and master server side

Thanks a million

Do you have a single master/media server or additional media server (s)? If media servers, test name lookup and connectivity tests in all directions. Please show us output of these commands on master (and media servers ) for the client hostname that backup is failing for. (Please firstly check client hostname used in Policy. Make a note of the spelling. Exactly. Including case, shortname or FQDN. Double-check for typo error in Policy as well in hosts file.) 1) ping 'client-name' 2) bpclntcmd -hn 'client-name' 3) bpclntcmd -ip 'client-ip'

Dear Marinne,

 

Please note the backup of these servers are taken through the Master server as Media server noting that we have other media servers, and the policies of these clients were created long time ago, plesa check the below result:

 

root@mcmp:/>ping hs-netboss-dr
hs-netboss-dr is alive


root@mcmp:/>bpclntcmd -hn hs-netboss-dr
host hs-netboss-dr: hs-netboss-dr at 10.1.112.36
aliases:     hs-netboss-dr     10.1.112.36


root@mcmp:/>bpclntcmd -ip 10.1.112.36
host 10.1.112.36: hs-netboss-dr at 10.1.112.36
aliases:     hs-netboss-dr     10.1.112.36

---------------------------------------------------------------------------------------------

root@mcmp:/>ping cctvcc01
cctvcc01 is alive


root@mcmp:/>bpclntcmd -hn cctvcc01     
host cctvcc01: cctvcc01 at 10.1.112.84
aliases:     cctvcc01     10.1.112.84


root@mcmp:/>bpclntcmd -ip 10.1.112.84
host 10.1.112.84: cctvcc01 at 10.1.112.84
aliases:     cctvcc01     10.1.112.84

Just for the purpose of testing are you able to backup these clients in a test policy with the ipaddress instead on hostname to isolate any firewall related issues?

 

Also if you can take a look at bpcd,vnetd and pbx logs you might see some reasons for failure...

Dears,

 

Kindly note there is NO Firewall between these servers, please check the attached logs

Have you updated hosts file on client cctvcc01 as well? Did you clear host cache on client after updating hosts file? Have you done same bpclntcmd tests on the clients? Please ensure that bpcd log folder exists on the client, then perform bptestbpcd connection test on the master to the client: bptestbpcd -client cctvcc01 -debug -verbose Please post output as well as client's bpcd log file.

Dear All,

Kindly note the problem was solved when our network admin updates the IPs on the Switch Firewall records and cleared hosts cache

 

Many thanks
