On Tap Version supported for vsphere 5.1 for ibm Netaap FC storage N6070 AND N7900

Hi, Recently we have upgraded our 4.1 environment to 5.1,but after upgrade, we are having continuous issue ..for.

Lun Latency & Host disconnected form VC 5.1 ?

is there any relation b/w lun latency and host disconnceted form vc ?

and Data Ontap version on san [NETAPP N6070& N7900] is: 7.3.5.1P1 - is it compatible to be used with 5.1 ?

And SAN [N6070/N7900]we are accessing form IBM Rack Server X 3850[TYPE 7145] using EMULEX HBA[LPe12000 8gb FC Host adapter] in active active mode with round robin policy - Is this config fine to be used in 5.1 or if we may have to upgrade any firmware/driver ?

please advice if ontap upgrade is the reason behind this issue?

and is host disconnect occurring due to lun latency ?

and best practice to look more into this ?

is it require to configure any policy at san volume level for snapshpot reservation/fast processing ?

And what is the role of VSC(virtual storage console) plugin..if we can use it on vc or any of esxi host ?

Did you raise a support request with IBM and VMware of your issue, to ensure the fabric is compatible.

and this includes

hba, firmware of hba, version of ESXi 5.1 and OnTap version with hba firmware version, and also physical FC switches.???
