Configuring MPIO for 2012 R2 SOFS

Question

Setting up a 2 node 2012 R2 SOFS. I have 2 2012 R2 nodes,each with 3 - dual port LSI SAS HBAs and 3 Data-On Jbods. All HBAs, jbods certified for storage spaces.
I have enabaled MPIO on both nodes and enabled SAS device support in MPIO CPL and rebooted. Is that all there is to it? How can I tell if MPIO is setup and running properly? Here are some of the commands if tried
PS C:\Users\administrator> Get-MSDSMAutomaticClaimSettings
Name                           Value
iSCSI                          False
SAS                            True
PS C:\Users\administrator> Get-MSDSMGlobalDefaultLoadBalancePolicy
None
VendorId ProductId        IsMultipathed   IsSPC3Supported BusType
HGST     HUS726060ALS640  True            False           SAS
STEC     S842E400M2       True            False           SAS
PS C:\Users\administrator> Get-MPIOSetting
PathVerificationState     : Disabled
PathVerificationPeriod    : 30
PDORemovePeriod           : 20
RetryCount                : 3
RetryInterval             : 1
UseCustomPathRecoveryTime : Disabled
CustomPathRecoveryTime    : 40
DiskTimeoutValue          : 60
Also not sure if this relates or not, when I run get-storageenclosure I get this:  I have 3 Jbods
PS C:\Users\administrator> Get-StorageEnclosure
FriendlyName                  HealthStatus                  NumberOfSlots                 ElementTypesInError
StorageEnclosure0             Healthy                       24
StorageEnclosure2             Healthy                       24
StorageEnclosure1             Healthy                       24
StorageEnclosure3             Healthy                       24
StorageEnclosure5             Healthy                       24
StorageEnclosure4             Healthy                       24
Thank you for your time

Hi!
But is this really normal? We have 3 enclosures and Get-StorageEnclosure shows 6 enclosures with different names. We have created virtual disk with EnclosureAware option set to true and tried to switch one enclosure off. Virtual disk had failed after this.
Looks like Storage Spaces think, that I really have 6 enclosures and 2 of them went down, so enclosure aware is not working properly.
We use Supermicro's servers as an enclosures. Here are one of them (this must be one enclosure, but it is duplicated):
