Backup Exec 2012 – HP MSL 2024

I installed Backup Exec 2012 on a new DL380 Machine which I connected to our HP MSL 2024. When I started to backup our environments all the backup’s ran into problems.

They all run into one of this two errors:

  1. Adamm Mover Error: Write Failure!
  2. An unknown error has occurred.

And for both Symantec Backup Exec 2012 blamed the tape drive. A device attached to the computer doesn’t work correctly. I ran all the HP Tape storage tools tests and they all indicated that the MSL was working correctly. After digging into google I found the solution for this problem on the site from Symantec  (

Disabling SCSI Information from HP did the trick. 

Disable the HP Management Agents:  
Go to Control Panel > HP Management Agents, select the Services tab, then move SCSI Information to the Inactive Agents column.  Retry the backup job.
If it still fails, try moving the performance monitor agent to the disabled column and try the backup again.
Disable the following HP services, and reboot the server and test another backup:  –  HP Insight Server Agents
–  HP Insight Storage Agents
–  HP Insight Foundation Agents
   –  HP WMI Storage Providers service
NOTE: Not all three services may be present. Only disable what is listed above.
