Abstract

Using the IBM BladeCenter Management Module TCP management interface port and code logic, we provide a method to update the firmware of the primary and redundant Management Modules in any situation with the exception of those that have code levels less than 57 and have their IP addresses configured via a DHCP server. The only known solution for this problem is to perform the firmware updates manually and locally to the BladeCenter chassis.

Method for remote, unattended update of redundant BladeCenter Management Module (MM) firmware

     Inability to perform remote, unattended firmware updates of the IBM BladeCenter Management Modules, herein referred to as MM or MMs, in a redundant environment due to many different code levels, some of which do not support redundant MMs, different functionality between the code levels, and possible mismatches in the code levels. The details of the code levels and functionality are as follows.

     Primary and redundant code levels greater than or equal to (>=) 27 (the initial MM code level release) but less than 52:
These code levels do not support redundant MMs, however, there is nothing to prevent users from inserting a redundant MM.

     Primary and redundant code levels greater than or equal to (>=) 52 but less than 57:
These code levels support redundant MMs, however, they do not support automatically flashing the redundant MM to the same code level as the primary MM. This results in the redundant MM having a code level that is different and down-level than that of the primary MM.

     Primary and redundant code levels greater than or equal to (>=) 57: These code levels support redundant MMs and have the ability to automatically flash the redundant MM to the same code level.

     Primary code level greater than or equal to (>=) 52, redundant code level less than 52:
If the primary MM code level is greater than 52, it supports redundancy, however, if the primary MM fails over, the code level of the redundant MM does not and therefore will not know about the redundant MM which was previously the primary MM before the failover.

     Primary code level greater than or equal to (>=) 57, redundant code level less than 57 but greater than 52:
The primary MM will know how to automatically flash the redundant MM, however, if the redundant MM h...
