I faced a challenge during a DPM implementation when trying to get a DELL TL2000 tape library to work properly using the cleaning media.The problem I was facing was that the actual slot for the cleaning tape went missing.
To solve this you must add a registry value to the DPM sever. Add a DWORD named RSMCompatMode under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent with the value of 8.
The RSMCompatMode is used to specify several flags for DPM. The following are the flags that are set by this registry value:
- 1 = RSM_COMPAT_INIT_ELEMENT_STATUS
- 4 = RSM_COMPAT_IGNORE_TAPE_INVENTORY_RESULT
- 8 = RSM_COMPAT_CLEANER_EXCEPTION
Restart the DPM server after you added the registry key and perform a rescan if the slot doesn’t show up immediately.
