Some Fibre Channel Host Bus Adapters Are Not Initialized When Boot BIOS Is Enabled
Enabling Boot BIOS on Qlogic/Emulex HBAs prevents the HBAs from initializing with the following error message:
PCI resource allocation failure
This problem is caused by the HBAs' memory usage during initial bootup. This is a Qlogic/Emulex third-party limitation.
IBM suggests rearranging the sequence in which NVRAMs are loaded. The problem can be also be avoided by disabling other devices.
