We're experiencing a weird problem with our Fiber Channel / SAN setup on our vSphere servers. We recently upgraded 4 of them from ESX 3.5 to vSphere 4 and have noticed that, when managing the paths for these devices, we see that out of two paths, the Target field is blank for one of the paths. This occurs on 3 out of 4 of the hosts. Problem is, we're not sure if we ever observed this behaviour when they were running ESX 3.5 - and we're not sure if this is a vSphere quirk or whether it's a fault of our setup.
Thing is, the path does work fine. We run these two paths in MRU and we can merrily failover between the two without any problems but the target value remains blank.
Interestingly I turned up this KB article from VMware: - this relates to iSCSI specifically which we're not using but does sound identical. Wondering if the bug does also affect FC devices as well as iSCSI?
Thanks in advance.
