Sounds like you have a problem with the robot.

Check the application log in event viewer for error if the media server is windows or /var/adm/messages file if Solaris, or check the syslog for the OS that the media server is running.

Might be an idea to stop and start netbackup on the media server and see what happens.

i.e if windows run <install dir>\netbackup\bin\bpdown -v

make sure that all processes is stopping running install dir>\netbackup\bin\bpps, if processes does not stop, end the process in the task manager.

If Unix run /usr/openv/netbackup/bin/goodies/netbackup stop

if run bpps -a to make sure all process is stopped, if you still have processes hanging, run /usr/openv/netbackup/bin/bp.kill_all

Start netbackup again running /usr/openv/netbackup/bin/goodies/netbackup start

Create netbackup log folders

media server

/usr/openv/netbackup/logs/bpbrm
/usr/openv/netbackup/logs/bptm

on the oracle server
/usr/openv/netbackup/logs/bpcd
/usr/openv/netbackup/logs/bphdb
/usr/openv/netbackup/logs/dbclient
chmod 777 dbclient

If windows, path will be <install dir>\netbackup\logs

Recreate the problem and check the syslog in the OS and the logs created in above folders and take the required actions.

if you still have problem with the robot, try to run /usr/openv/volmgr/bin/robtest to mount and unmount a tape.

I hope this helps.

Try this

-Suspected recovery catalogs not installed & The database to be backed up is not registered.
-Created a user to hold the recovery catalog.
-Then created the recovery catalog.
-Each database to be backed up by RMAN is registered before we attempt a backup.
-Created a user to hold the recovery catalog:

CONNECT sys/password@InstanceName AS SYSDBA

-- Create tablepsace to hold repository

CREATE TABLESPACE "RMAN"

CREATE USER rman IDENTIFIED BY rman

-Registered Database

RMAN> register database;

Thanks for your reply....

But Failure for this backup is not related to Catalog backup. Its only RMAN .

PraveenCH · ‎07-02-2011

RMAN backup is taken on same server as SAN media server or on to different media server?

What is the status of the concerned tape drives and robot?

Also check if there are any pending requests on the specific Tape and Drive.

you check Pending requests in GUI or command line using "nbrbutil" command.

>bperror -S 98 -r
error requesting media (tpreq)
The tape manager (bptm) received an error when they requested a media mount from the following: the NetBackup Device Manager service (on Windows) or the Media Manager device daemon (ltid) (on UNIX and Linux).

Do the following, as appropriate:
* Check the NetBackup Problems report to determine the reason for the failure. The most common cause is that the NetBackup Device Manager service (on Windows) or the Media Manager device daemon (ltid) (on UNIX and Linux) is not running. Start it if necessary.

PLEASE mention you NBU version as well OS on media server experiencing status 98.
There are a couple of TN's related to bugs in specific NBU version and others related to specific OS.

Please also ensure that you have logging enabled on media server: bptm folder under netbackup/logs as well as VERBOSE entry in vm.conf (in volmgr folder). Restart NBU on media server for VERBOSE entry to take effect.
