IBM 3650m2/3850 does not start from the local hard disk from the storage?

I worked overtime at the Postal Service on Saturday and encountered an unexpected problem.
IBM 3650M2 this is IBM borrowed from other distributors, 1 c4g low configuration, system installed 5.0sp2 x86-64, in addition to the NIC needs a single plus driver, everything else normal. Link the IBMDS4700 disk array and divide some Luns into the host. The problem is that after the LUN is divided.
Originally, the 3650 system can be restarted normally after it is installed, and the network is connected after the NIC driver, and the storage LUN can be identified. After rdac is installed, it cannot be started. The system prompts that the optical drive, the soft drive, and hard disk 0 failed, and then tries to start from the NIC. The startup sequence is not adjustable. After analyzing the cause, it may be a problem with the optical fiber cable, so it is normal to unplug the optical fiber.
From the perspective of the phenomenon, when the optical fiber is inserted, the hard disk 0 becomes the LUN on the storage, and the RAID card is pulled out at the cost. However, no adjustable options are found in the BIOS and qla card configurations, so some people suspect that the microcode of the optical fiber card or hardware is too low, and suspect that the id number of the LUN division cannot start from 0. All tests may have been performed, but they are not resolved.
Finally, I found the CAPTCHA engineer and got it done twice.
The reason is that in bios 3650m2, hard disk 0 of the startup option does represent both the qla Optical Fiber card and the local RAID card. As long as the optical fiber is attached, the LUN on the storage will start from the storage, it can be said that the storage priority is relatively high. You can add a "lagac only" in the bios boot item. Before this parameter is adjusted to hard disk 0, this indicates the local disk.
Although the problem was solved, it was impossible to check the Internet because there was no network at the time. The CAPTCHA engineer said there was a case on the ibm official website.
