Best Practice for large Netbackup/Tape Drive Environment
Hi all, first time poster. looking forward to the experience.
Ok, I work with Netbackup 7.0.1, with a Clustered Unix Master server, 40 Media servers.
Backup capacity about 500TB/week.
Our tape drive environment is 2 SL3000's, one on the production environment(32 drives, 2 robotic arms) and another at the DR environment(14)
All drives are SSO configuration, all media servers can access all drives.
Our challenge is the setup is unstable, regularly we have issues where all configured drives on a media server go to AVR mode, and multiple instance of tldcd processes spawned on the Master Server, often leading to backups failing with error code 98.
My question is, Is there a more efficient way to manage/configure this environment?
Would love to hear your ideas...
