Backup Exec 2010 R2 "an unknown error occurred" HP Server Management Agents

[Carolin Mauser]

Windows 2008 R2 with Symantec Backup Exec 2010 R2. HP Server Management Agents software installed.
Backing up to tape creates error: "an unknown error occurred".

Disabling HP WMI Storage Providers service and disabling the HP Management Agents (Nr. 4 of the article above) helped.
What can I do to solve the problem with all HP Management Agents fully actice?
