Internal Drive Enclosure Port Numbering - explanation?

[Crestj]

I have a DL380 Gen 10 and DL325 Gen10 with identical P408i-a SR array controllers.

When I look at the physical drives in each server (through ILO or using ilorest) I see that the DL380 Gen10 shows the drives as follows:

[1]: 1I:3:3
[2]: 1I:3:2
[3]: 1I:3:1

This is exactly as I would have expected [Controller Port (Internal)]:[Box]:[Bay]

However, when I run this on the DL325 Gen10 it seems to add an extra character which I cannot determine its meaning!

[1]: P1I:1:1
[2]: P1I:1:2

Does anyone know what this added "P" means and why it appearing?!?!?!?!

Please log a HPE support case with screenshots of ILO and AHS logs from both server.

I can certainly do that but does your reply indicate that this "shouldn't" be displayed in this way?

Is this by design or a bug?
