I've noticed some annoyingly odd behavior in that when the policy attribute window is open in NetBackup Admin Console, it will not let me have the "Use Acclerator" option checked and gives the following error:
"To use the accelerator, select storage units from a supported storage server: PureDisk Deduplication (PPDO), Media Server Deduplication (MSDP), Symantec clouds, and other qualified storage servers. Currently configured and supported storage servers are: <none>"
I cannot move past this error without cancelling my policy changes.
However, I can enable it with the Java console with no problem or errors? WHY? I've seen this on both 5220 and 5230 master/media servers in pointing to the dedup pool.
I've seen a thread where the Optimized Image flag needs to be enabled. (which it is)

Or it could be a license issue if this option is not seen: (However in my instance, Accelerator is enabled per the license)
Feature ID = 88 Accelerator +
