How to check the status of the HBA, the HDDs and the M.2 SSD devices on BDA X7-2L or BDA X8-2L nodes from the system BIOS (Doc ID 2868373.1)

Information in this document applies to any platform.


All versions of BDA server nodes have 12 internal HDDs. They also have another internal boot device.
Older, legacy hardware (X6-2L and before) have a USB device.  Newer hardware (x7-2L and x8-2L) have M.2 SDD devices.

The default BIOS boot order on BDA is (either the M.2 SSD or USB) first, then the HBA next, and then lastly the PXE.

The BDA x7-2L and x8-2L nodes should boot from the internal M.2 SSD device first but could actually boot from something else depending on several factors.

Under normal (optimal) conditions, if
   there are no active faults logged in on the ILOM (or in the ILOM snapshot), and
   the node has successfully completed POST and if
   the HBA (and it's SuperCap), the 12 HDDs and the two M.2 devices are all healthy and optimal
   there should be no hardware problems that would prevent the BDA OS from presenting the grub menu.  If the BDA OS grub is not presented, the software raid on M.2 SSDs or the HDDs may be corrupted and should be checked. 

This note explains how to check the hardware health of the boot related devices from the system BIOS:  the HBA (and the HBA SuperCap), the 12 HDDs, and the two M.2 SSD devices.

The examples below are from an X7-2L node, the X8-2L will look very similar, but the small hardware differences can be expected.
