Netbackup 7.5.0.4 Master not communicating with 6.5.4 San media Server

Created: 04 Nov 2012 | 11 comments
Sammeer_Pednegar's picture

Hi,

We have upgraded to a new Solaris 10 T4 master server yesterday and we have upgraded Netbackup from 6.5.4 to 7.5.0.4 on the same box.

Now we are facing an issue wherein all the San Media server are facing intermittent corba communication issues wherein backups fail with status 195.

We are not facing any issues on the lan clients.

We have logged a case with technical support which is currently in progress however there is no resolution yet in sight.

Kindly suggest.

Did you replace the existing master server with new T4?

Have you already checked network communiation between master server and SAN Media server?
Check if SAN media server is listed in master's bp.conf as SERVER.

Hi Yashuhisa

We replace the existing Master V440 solaris 10 with a new T4 Master Server.

We installed 6.5.4 and performed a catalog recovery on the new T4 Master.

Tested Lan client backups and found no issues.

When we tested San Media server backups it failed with Status 195.

Tried vmoprcmd from Master Server to San media server and got Corba communication errors intermittently.

The only change between the old master and new master is Network Teaming was not present on the old master while the new master we have incorporated teaming.

Please suggest

You mention you started with NetBackup v6.5.4 on your new hardware; did you test SAN Media server backups after the initial catalog recovery?  Did they work or have they started breaking after the Master Server upgrade to v7.5.0.4?

intermittently? Not always got failed?
Please check network communication between master server and SAN media server without NetBackup. Try telnet, ftp, ssh or so and observe if any error or significant perforamce degration occurs.

To verify your configuration, please post output of following commands on both host.

bpps -x
bpclntcmd -self
bpclntcmd -pn
grep SERVER /usr/openv/netbackup/bp.conf
bptestbpcd -verose -host

Hi Marianne

We have backline Engg with us who have found there are servers which are flooding the master server with pings.

We have found there are four servers which are causing this scenario and they no longer exist in  netbackup configuration. We do not have access to these servers hence would like to know how to block these from pinging the netbackup master.

i think the network guys can help you here. they can perhaps block connection or may be you can use the OS firewall setting to block request from those servers
