Initiator does not have any initiator paths

Hello

We have Unity 380, software version 5.3.0.0.5.120.

Everything looks correct, all cables connected and green on the system overview - enclosures; but when looking at the initiators tab, it shows 2 of our servers have 1 good connection, and 1 in error (see below).  Even though the overall condition of the hosts is good.

We have 2 SAN switches linked, and it looks like the secondary switch is the 1 with the error.

Is this an error, or is this just because the second link is a backup?

Thanks in advance,

Michael.
