mpr driver does not show all paths to dual-port disks. 

Tested on 2 LSI 9300-8e connected to HP D2700 （SAS2) disk external enclosure with 12 HDDs on HP DL360p Gen9 and HP D3700 (SAS3) disk enclosure with 10 SSDs and Supermicro X10SRH-CLN4F, FreeBSD 12.1 and 12.2

Same hardware setup works perfectly on Linux.

mps driver (LSI 9207-8e) also works fine in FreeBSD

I attached dmesg.log, geom, mprutil and sesutil output

as you can see from geom output it can see only 1 device with 2 paths

Comment 5 Maarten 2021-03-19 17:23:46 UTC 
Reproduced on HP DL380 Gen10 with LSI 9300-8e(FW:16.00.12.00) connected to HPE D3610(FW:5.04) enclosure with 6 HDDs
Same issue only "last" HDD in enclosure has 2 paths

An other server with the same setup has no issues, only difference:
- it currently has only 2 HDDs(same series)
- the HPE D3610 enclosure has an older firmware 3.64 instead of 5.04
