MSDP - storage server down

Running NB 7.7.1

Master is RedHat

Media servers are 2012 R2

Media servers access tape drives via fc - no issues.

Media servers have luns for MSDP - E: for dedup database and Drive F: for dedup data

Drives are showing online and healthy on all media servers.

Am getting status 2106 on all backups to mdsp storage units - and noticed that the storage server was showing down - but disk pool is up

From master:

  • I have moved this post to the NetBackup forum as this is not standalone PureDisk product. Sure about NBU version? Why is nbdevquery showing 7.5?
