After an upgrade to ESXi 5.5U1 (Dell R710) from ESXi 5.0 two of the four ports of a QLE2464 HBA are no longer present.
I tried disabling the in-box qlnativefc module and running with the in-box qla2xxx module - the symptoms are the same.
The first two ports work fine and the last two are not configured/don't appear in the storage core adapter list.
There should be support for the qla2xxx cards - what about the quad port version?. Any assistance welcome.
