Fun with blades

Was assisting a client with their blade servers today. Apparently their blade server  decided booting from LUN0 (HDD) from the integrated SAN storage was less preferred than PXE, so it was hanging at the Network Boot Agent prompt. Some reordering in BIOS, and all is fine again. They also had an issue with being unable to add a hotspare drive to the pool, which required a full shutdown of the blade.
