Backup of AIX Client goes into HUNG

Hi,

I Apologize for late reply to My Query.

But i havent got the Permanat Solution.

I will Be able to take backup of AIX Client by two ways.

1. Increasing Client Parallelism.

2. Restarting of nsr Services.(need to Clear JOBSDB).

but after few days its again goes to HUNG.

Thanks

Hi Carlos,

Thanks for your reply.

Connectivity is fine from server as well as Client side.

also i am able to take backup from server side.

as i replied once the bakup goes into HUNG (after 10-15 days). to workaround I will be increasing Client Parallelism/restart nsr services.

As per my Knoweldge its something related  to HUNG Session of that particular AIX Client in jobsdb.

what do you think?

Thanks

Sainath

Hello Sainath,

I believe that could be a connectivity issue.

If you are able to run a backup by increasing client parallelism I suspect some hanging sessions on the client side.

Have you checked client side logs?

When you are not able to run backups server initiated, are you able to run backups form the client?

For example try this command:

save -D3vvv -s NW_SERVER_NAME -b POOL_NAME /etc/hosts

Thank you,

Carlos

Hello Sainath,

I agree. I think that sessions are let's say "in use" by the NW server, so that's why I was thinking about some potential connectivity issues maybe on the client side.

Next time when you find that behaviour check the ports in use on the client side (rpcinfo -p NW_SERVER from client and rpcinfo -p CLIENT:NAME from NW server) as well as netstat -a to determine the ports being used.

Also if possible, run at the same time the save command I sent you before, run it from the client and check the output. That could give us some more clues.

You can always check to run the following command on the client and check if it gives you the prompt:

nsradmin -s NW_SERVER -p nsrexec

Thank you,

Carlos

Hi Carlos,

As per you suggestion i will definately check and update you.

Thanks

Sainath

When this happens, check your alerts in NMC.  It may have something to do with devices and media pool.

Hi Xao,

I have Checked Log & find below detail.

"Cannot determine status of backup process.  Use mminfo to determine job status"

Also I have search on EMC document found that we are usually facing this problem if there is issue in build of binaries.

however  Client Initiated & SAP backup is running Fine

1. package installed on Client LGTOnw.clnt.rte            7.6.3.5  COMMITTED  NetWorker Client

2. pacakge installed on Server:  NetWorker 7.6.3.3.Build.870 Enterprise Edition

Thanks

Hi Carlos,

I have checked port & listening port of service nsrexec

also the command you have provided excuted sucessfully.

However SAP & Client initiated backup is running sucessfully.

Thanks

It appears your control session has dies or has been terminated.  Set NSR_KEEPALIVE_WAIT for some reasonable value on both server/storage node and client and try again (requires application restart).

Hi All,

Finally got solution.

i have written save -c "FQDN name of Client" in backup command of Client properties.

and it works
