from client execute  /netbackup/bin/bpclntcmd -pn and -self

from master/media server /netbackup/bin/bpclntcmd -ip and -hn  to client 

at client end enable bpcd logs (if doesn't exist create directory named bpcd under /netbackup/logs)

increase verbosity to 5 using BAR gui. file-netbackup client settings -troubleshooting,

post output from master server /bin/admincmd/bptestbpcd -client hostname -verbose -debug

 

If  it's 7.1 and later from support   directory executte nbdna -verbose . it would analyze netbackup domain and will tell you if any of required ports are blocked..

If ping is not working, then basic TCP/IP comms is not working.

Your client is either behind a firewall where ping is disabled and ports are blocked, or you don't have /etc/hosts entries on server and/or client.

Please post the following info:

NBU version on Master, media and client

OS on Master, media and client

Firewall requirements are different for the various NBU versions. Looking at your other posts, it seems as if you have a mix of NBU versions in your environment - from 5.0 to 7.0.

We can provide better advice if you share all relevant info in your opening post (like OS and NBU versions).

If ping and telnet are not working, you need to address this from the 'network' side.  This is NOT a NetBackup issue.

Do you have a Network administrator who can assist you ?

Get your network admins to check

1) No firewall is preventing comms

2) That comms on the client are actually up and running

3) That the routing from Master to client and client to Master is correct

4) That the Master has the correct IP for the client and vice versa

 

Get that sorted and get ping working first before even looking at NetBackup.

NBU Version on Master server is 6.5.6

NBU version on client is 6.5.4

 

OS on master server is solaris

 

OS on client is Window 2003

 

Client is not behind firewall or having proper entries in etc/hosts on master as well as client

Is ping working yet between master server and client yet?

As stated above, this is not a NetBackup issue.  You need to work with your network admins to determine why you cannot ping from the master to the client. 

Try pinging the client by name and by IP. 

  • If you can ping the IP address but not the name, your DNS entry for the client, or /etc/hosts file on the master server, are wrong.  Correct them.
  • If you can't ping it by either the name or the IP address, then there *is* likely a firewall set up preventing communication, or the client's IP address in both DNS *and* in your /etc/hosts file (if you have it defined there) is wrong.  Correct them.

perform steps mentioned in my previous post. Execute NBDNA. This would let us know which ports are getting blocked. Also if possible try to reset network connection from switch end.

Check with netstat and see how many connections to that perticular client are in established  , sync, state. There could be connections are getting established but not acknowledged by client..

If  possible take downtime for reboot and check.
