An integrator installs an HPE ProLiant BL 460c Gen9 server into an HPE c7000 BladeSystem Enclosure that has HPE Virtual Connect Flex-10 Ethernet modules in interconnect bays 1 and 2, and HPE Virtual Connect 8Gb 24-Port Fibre Channel modules in interconnect bays 3-6. The blade is configured with two HPE LPe1605 16Gb Fibre Channel HBAs in mezzanine slots 1 and 2, 32 Gb memory, and a single E-2600 v3 processor.
Next, the integrator installs ESXi 5.5 update 2 on the server. However, only one HBA is recognized in the operating system. As a troubleshooting step, the integrator replaces the HBAs in the problem server with known working HBAs from another server. However, ESXi still recognizes only one HBA.
Which step should the integrator take to allow the server to recognize both HBAs?
