INIT failed status and Problem communicating with BSMP on IBM Blade Chassis

I have a fully loaded Blade Chassis H (ie 14 Blades). I have the following symptoms similar to what was written in IBM Site INIT failed status - IBM BladeCenter HS22, HS22V

   

0X0021600 / Symptom:

BladeCenter HS22 or HS22V status is reported as Init Failed and the following error is posted in the Advanced Management Module (AMM) event log:

0x00216000 Problem communicating with BSMP

The chassis has 14 blades installed.

Workaround:

Remove one blade from the chassis.

Solution:
Install AMM firmware v3.54L (BPET54L) or later.

The file is available by selecting the appropriate machine type on the 'Software and device drivers - IBM BladeCenter' web page, at the following URL:

Patching

Select the correct Blade Chassis Product. Since I am using Blade Chassis H, my fixes were

ibm_fw_amm_bpet62o_anyos_noarch
(IBM BladeCenter Advanced Management Module Firmware Update)

The patching will require restart of the AMM. Restarting the Advanced Management Module will disconnect your current session. 

Blade hangs on boot and "FW/BIOS, firmware progress (ABR Status) FW/BIOS ROM corruption

2 of my Blade got hang on boot and suffered this "FW/BIOS, firmware progress (ABR Status) FW/BIOS ROM corruption".

Symptom
When booting BladeCenter HS22 or HS22V with Integrated Management Module (IMM) build yuoo84c installed, the blade may hang at the "UEFI Platform Initializing" screen. The hang will be accompanied by the following event in the chassis Advanced Management Module (AMM) log:
   
FW/BIOS, firmware progress (ABR Status) FW/BIOS ROM corruption

---

Solution
This behavior is corrected in IMM firmware release yuoo91e and newer.
The file is or will be available by selecting the appropriate machine type on the 'Product View' of IBM Support's Fix Central web page, at the following URL:
http://www.ibm.com/support/fixcentral/systemx/groupView?query.productGroup=ibm%2FBladeCenter

---

Workaround
This failure may be reduced by disabling Internet Protocol Version 6 (IPv6) support for the IMM. This can be done via the following steps:
1. Boot the blade to the F1 Unified Extensible Firmware Interface (UEFI) setup screen.
2. Select "System Settings" and press Enter
3. Select "Integrated Management Module" and press Enter
4. Select "Network Configuration" and press Enter
5. Change "IP6" setting to "Disable"
Occasionally, the failure can be recovered by restarting the IMM. If this is not successful, then it is necessary to reseat the blade in the chassis to recover. After a reseat, the blade will boot normally.
