Environment

ESXI (All Versions)

Cause

The FC HBA has been tagged for VM passthrough, this will prevent the ESXI host form seeing any luns presented to this HBA.  This is used to present the HBA directly to a Guest.

Resolution

Disable PCI passthrough

Via <ESXi Host> Configure tab, expand Hardware and click PCI Devices. 

You should see the PCI device listed under the passthrough tab.  Locate and select the device and click toggle passthrough 

Once toggle passthrough has been clicked this will disable Passthrough and you should no longer see the PCI device listed under Passthrough-enabled devices and see the HBA listed under storage adapters. At this point all presented LUNs should show correctly.  If you do not see a change after this action please reboot the host and verify the HBA is no longer in Passthrough mode. 

If this does not resolve your issue please open a new SR with VMware by Broadcom
