Hello,
The scenario:
I have two freshly installed ESXI 5.5 machines, both are connected with dual mini-scsi cables (one per controller) each host from my HP G3 SAS MSA Storage, which is also freshly installed.
The problem:
From this fresh installation I am seeing both paths in datastore properties but when I choose round robin it NEVER switches between the two paths, so I'm effectively using just one.
If i use Fixed policy I can tell it to use either path and there I'm able to verify that both paths work even though one is alot slower (and changing HP Controller did not change this).
Why doesn't round robin work? How do I get it to work? HP is sure their hardware is not faulty so I'm hoping there are common problems with round robin I can look into.
Br,
Joakim
