Re-Configuration of TLD Devices in Media Server

[winter_prince]

Hi Friends,

I am little experience in Netbackup and have mostly only theoretical knowledge of concepts...

I need help in reconfiguration of devices in a media server.

Netbackup Environment: 7.5 (Master, Media and Client)

Media server (AIX) is configured with 2 TLDs (SSO Enabled and both are from different robotic hosts). I Need to reconfigure this server, as many device paths are missing.

My assumption is the following:

• Stop Media Server Services.
• Remove devices from Netbackup.
• Remove devices from OS level.

• Re-discover devices from OS level.
• Configure the devices in Netbackup using "Device Configuration Wizard"

Can someone direct me along the right way to do this...? I am not able to find much information on this.

Regards,
Prince

If I understand correctly the robot control host is a different media server, right?

In that case, your steps look good.

Yes, correct.. Robotic control host is a different server.

Thank you Marianne... Did reconfigure the devices successfully... 

Steps I followed.... 

1. Stop Netbackup/Media Server Services.

/usr/openv/netbackup/bin/goodies/netbackup stop
/opt/VRTSpbx/bin/vxpbx_exchanged stop

Verify whether all the services have stopped.

2. Remove media/devices from Netbackup.

/opt/openv/netbackup/bin/admincmd/nbemmcmd -deletealldevices -machinename kpgnbu16abs -machinetype media

3. Remove Devices from OS Level:

rmdev -dl <Device Names>

4. Re-discover devices from OS level and verify (AIX).

# cfgmgr
# lsdev -Cc tape
# /usr/openv/volmgr/bin/scan

5. Configure Devices for netbackup from os level:

#tpautoconf -a

verify:

#tpautoconf -r
#tpautoconf -l

6. Configure the devices in Netbackup using "Device Configuration Wizard"

7. Start Netbackup/Media Server Services.

/usr/openv/netbackup/bin/goodies/netbackup start
/opt/VRTSpbx/bin/vxpbx_exchanged start

I didnt do the 6th one though... I know its best to use the "Device Configuration Wizard"... Is there a better command line alternative for this task ?

I have one stupid doubt here though.... In a scenario, where only one of the TLDs have issues... how do I do re-configuration only for that particular TLD along with its drives.

Thanks,
Prince.

Reconfig of robot depends on the OS. If AIX, the question is if it is IBM or non-IBM robot.
Symantec no longer supports non-IBM robots on AIX due to 'issues' with ovpass devices. 
See NetBackup 7 Hardware Compatibility List (HCL):    http://www.symantec.com/docs/TECH76495 

I have bookmarked this post from an AIX/NBU expert: AIX Media Servers for Dummies..... 

This doc will help you with robot config on all supported OS's:
