B200 M5 Equipment Stopped During Boot.

[Lee.]

안녕. 이임박사

UCS B200 M5의 증상.
OS 재설치를 위해서는 네트워크 부팅 과정이 필요합니다.
다만, 재부팅 후 부팅시 LSI MegaRAID 상태창이 나타나고 이후에는 커서만 깜빡일 뿐 바이오스 진입 화면은 뜨지 않는다.

HA-0 Cisco FlexStorage 12G SAS 4.250.01-5047

1 호스트 어댑터에서 발견된 Virtual Drie

BIOS에서 처리하는 가상 드라이브 1개

<Ctrl><R>을 눌러 MegaRAID 구성 유틸리티 실행 <<<<<<

HA-0 초기화 중 잠시만 기다려 주십시오...

Ctrl + R을 눌러도 MegaRAID 구성 유틸리티로 이동하지 않습니다.
화면이 나오자마자 Ctrl + R을 누르면 아래와 같은 메시지가 나온 후 넘어가지 않습니다.

어떻게 해야 하나요?
도와주세요, 제발.

This server was hitting "FRB2" timeouts:

# 2062 | 12/21/2022 00:51:40 UTC | CIMC | Watchdog 2 BMC_WATCHDOG #0x6e | Hard reset. Timer Use: BIOS FRB2 | Asserted

But that stopped after CMOS was cleared:

# 206d | 12/21/2022 01:10:08 UTC | BIOS | System Firmware Progress #0x06 | System Firmware error | CMOS/NVRAM configuration cleared. | Asserted

After that it seems the server might be hitting something similar to CSCvu14656:

0:2022 Dec 21 01:10:31 UTC:MRC status = 00000002

But the server is on much older CIMC 3.1(26a) firmware which should not be impacted by CSCvu14656.

Several DIMMs show prior ECCs with A1 showing the most.
I would try removing DIMM A1 to see if the server gets further in POST.
Maybe go down to 1 DIMM  per CPU (A1 and G1) to see if the server gets further in POST.

If DIMM juggling doesn't work, then I would try to upgrade/downgrade firmware to see if this is a firmware issue.

Hope that helps.
