issue adding datastore to exsi hosts

Hi ,

 

I have issue adding datastore to exsi hosts using Unity 350F

the time I assign the hosts to vmware datastore a message will appear on all  hosts

 

"Degraded

The host does not have any initiators logged into the storage system. Register one or more initiators on the host to the storage system. This may also require zoning changes on the switches."

and the datastore will not show

but all initiators showing in storage side as will static discover on the host side
