Based on the two data logs submitted it indicates an issue wit the Master Server but for a potential issue of the client information submitted by the client itself.

In the 'bmrsavecfg' debug log (the 121 log), it shows completion of the process on the client as being successful with a completed 'bundle.dat' file.

04/16/2015 10:56:58.257 [CBmrSaveCfg::writeBundle()] Entering.

It's at this juncture that the process sends the file to the Master (by way of bpbrm) for insertion into the BMRDB.
The 'bmrd' log (id of 119) shows a problem for this:

16/04/2015 12:04:23.239 V-128-906 [ImportCfg.cpp:ImportConfig()] Unable to extract either ./bmrcli.xml or bmrcli.xml file from bundle. Cannot import.

The 'bmrd' process should fail out for the client import and signal back to 'bpbrm' of the non-zero return code. That should then trigger 'bpbrm' to move on and start the actual backup jobs.  It appears that this signaling is not happening for the process. The 'bpbrm' process just loops waiting for the process return and not getting anything.

To validate the bundle.dat file created on the client, do the steps to manually import the file on the Master.  You can create a new file running the command 'bmrsavecfg -infoonly' on the client and it will generate the client configuration file without any activity to the Master.  Then copy the newly created file (assuming no errors are displayed on the client) to a location on the Master Server and manually import that file into the BMRDB, using 'bmrs -o import -res Config -path $PATH_TO_bundle.dat_file'. As an example, if the Master is Unix/Linux and the file was copied to the /tmp directory, the invocation would be 'bmrs -o import -res Config -path /tmp/bundle.dat'. This will verify the validity of the client configuration. If that just hangs, then the client configuration, although created with no visible errors, has an issue parsing the file information and is hanging on something within it.  If need be attach the file to a reply for visual review and I can see if their is some sort of client configuration that was not supported in the 6.5.5 release it is coming from.

One last thing of note. In certain scenarios, the bpbrm process cannot properly handle the hand off of the BMR portion of the work and it crashes. If that is what happens, then the 'bmrd' process does not have a parent job to return the status code and the backups will also hang. This was seen in  later 7.X release (the version escapes me) where the job would get a status 26 error. One way to debug this is to check the 'bpbrm' debug log and look for the process id that was started as part of the backup.  See what happened to it.

Lastly, as noted multiple times above, an upgrade to a later version of NBU (one that is actually supported) is more than highly recommended.

Honestly! It's impossible to help if you do not reply to attempts to help you. Please go through each step in Jaime's last post. Lastly - use current issues as motivation to request NBU upgrade.

Hello Team

Sorry for very long and late reply to this post

 

still i'm facing the same issue

from master server i can see below logs

can any one help me on this

 

Hello Luc,

I have ran those commands and i'm attaching that log with this please check and clarify

 

 

The "hang" can occur due to issues on the client or issues on the Master.

On the client it can be one of two things. The process 'bmrsavecfg' is spinning and not completing, or the process is having issues sending the captured bundle.dat (the client configuration file) to the waiting bpbrm process.

On the Master, the reguklar NBU backup streams will not get kicked off until teh waiting bpbrm task gets teh bundle file and sends it off to bmrd to get imported. 

So, how t diagnose where the proces is failing:

1. On the client, set the DebugLevel for Orgid 121 to be 5. This is for the bmrsavecfg process.
vxlogcfg -a -p 51216 -o 121 -s "DebugLevel=5"
2. Run the bmrsavecfg process from teh command line:
bmrsavecfg -infoonly
3. If this proess runs to completion normally, then the problem is either getting the file to the Master or getting the file imported into the BMRDB
4. Copy the file "/usr/openv/netbackup/client/data/bundle.dat" to the Master Server.
5. Increase the debug level for the 'bmrd' process, OrgID 119, on the Master:
vxlogcfg -a -p 51216 -o 119 -s "DebugLevel=5"
5. Manually import the file into the BMRDB:
bmrs -o import -res config -path <path to bundle.dat file>
Again, if this completes in a normal 1-2 minutes, you are OK and the problem is some sort of communication error between the client and NBU Servers.

For failures on the client, get the log data with:
vxlogview -i 121
For failures on the Master, use:
vxlogview -i 119

Be aware that if either of the programs is caught in a loop, the debug log files will grow rather quickly.

Reset the DebugLevel back to default with:

vxlogcfg -a -p 51216 -o 121 -s "DebugLevel=1"
vxlogcfg -a -p 51216 -o 119 -s "DebugLevel=1"

In either case, I would highly recommend an upgrade to a 7.X reelase as it will allow for teh ability to open a support case for better assistance.

 

Do you have access to the client? If so try these commands...

/usr/openv/netbackup/bin/vxlogcfg -a -p 51216 -o 111 -s DebugLevel=6 -s DiagnosticLevel=6

/usr/openv/netbackup/bin/bmrsavecfg -infoonly

/usr/openv/netbackup/bin/vxlogview -p 51216 -i 121 -d all -t 00:10:00

Every thing is fine , but still its not picking

and where ever i try to stop the netbackup services in master server immeditly picking the backup

Is that means , any deamon stopping to pick the child streams ?

Verify host name to IP correct for client on the Master/Media  and for the Master/Media on the client.
