Apologies in advance if some of this is vague. I'm new to these sorts of projects, but I can provide more details if required...
We're creating a customer environment using an MD3620 array and two PowerVault servers that are hosting ESXi 5.5. On this particular build, vCenter is having a hard time detecting all of the iSCSI connections. When I go to add the storagein vCenter (configuration -> storage -> add storage) I'm only able to add one iSCSI connection per RAID controller. It doesn't matter which one I try to add/bind, only one is available. I've triple checked that the vmkernals are bound to only 1 port each and that the addressing is correct. Furthermore, when I check the iSCSI connections in MDSM, it says that all are connected and operational, and all of the addressing matches what I've set the vmkernals to (same subnet that is).
It seems to me that the hangup is with vCenter/ESX since MDSM reports all iSCSI interfaces are functional and connected. Has anyone else encountered this issue?
