Hi team
I have problem with the duplication with SLP, because the drives continuosly go down, and if the drives are up, the SLP dont use all of them. Also, if I run manual duplicattion`s, they run good....

Netbackup is 7.5.0.4, the master is installed in linux Redhat Red Hat Enterprise Linux Server release 6.7 (Santiago).
The master is HP ProLiant - DL380p Gen8 –

or /opt/openv/volmgr/bin/tpconfig -d
sometime the drives go UP, in others no, I need to restart Netbackup service or in worst case I need reboot the server.
What happen here ??
If you need any other information, please, ask to me.
Thanks for your support.

Hi Guys
The issue was resolved, aparently was caused for a low space in /opt/openv, the fs was full and I added more space, reestarted backup service, and these extranges problems dessapear...
Now, manual duplications and SLP's duplications run well.
But I have another issue now.. Will open other discussion.
Thanks for your cooperations!!!

Library firmware very old (2014), way past time for an update. There is also recent update for the tape drives. Call the vendor.

Know there has been a problem on some HP LTO3 tape drives, where the tape drives lost the login to the fabric wonder if the IBM tape drives could suffer from a similar problem.
Another thing that could cause this is changes in the SAN, if persistent binding is not used on the tape drives and library.
Regarding the SLP, check the number of concurrent write drives on the recieving storage unit.

Please check /usr/openv/netbackup/db/media/errors file for further error related Drive and Tapes. If you see hardware related errors, a call to hardware vendor is a must.

Hi
Will restore
The library firmware, I'm not sure if I can upgrade, because, we have some internal regulations, one sector, who decide if we can upgrading or not the firmware. I must investigate on internal way.
Michael, aparently the problem is only with duplications with SLP, if I use manual duplication they run well. When are running duplications SLP, not use all the drives. I see drives idle but, the duplications are in queue with the messages, there are not drives free .... DO you know if is an internal limitations for the SLP duplications runing at the same time? Some parameters or configurations?
SP.NBU
I check this file and I see this messages

What its mean?
Thanks for your cooperations.
