If I recall, it is more common to see them on filers with smaller memory
sizes (ie, 3020\270) than ones with larger memory sizes (960\980).
The 'D' CPs are new in 7.X (I don't remember exactly when it was
introduced).
Are you seeing any issues, by chance, or just hunting for problems to
proactively fix?

Subject: "D" CP types on FAS3020
Not been getting a clear answer from Support on this, maybe someone here
has some good advice or insight...
Our FAS3020C filers often display CP types of "D" in a sysstat listing.
I get that this is a CP due to "log datavecs." Trying to understand if
this is a resource problem, or at least indicative of a performance
issue:

One thing I got from Support is that it might be indicative of bug
145410 (must actively reclaim resources). At their suggestion, I've
updated to DOT 7.0.3 (update from 7.0.2), but still see them a lot of
the time.
Is this pretty normal for the FAS3000 series? Thanks in advance.
