Products Affected

CallManager - 5.1(1a)

 

Problem Description

The machine type and model string (MTM) handling change is applicable to software only IBM servers that were purchased after IBM rolled out their Xcellator ordering process are impacted, thus the install will fail with CallManager 5.1(1a).

Background

CallManager 5.1(1a) install fails due to a manufacturing change in the machine type and model (MTM) string. CallManager install uses a hardware table with the MTM to determine if a server is supported, and it checks on the first 6 digits of the MTM string.

Manufacturing's new ordering process changes the trailing 2 digits of the MTM string even though the server configuration still looks the same as before. This change causes all IBM servers to not be recognized by CallManager 5.1(1a) and the installation fails.

Problem Symptoms

Due to a manufacturing process change, the MTM string handling was changed, resulting in failure to install Cisco Unified CallManager 5.1(1a).

Workaround/Solution

Option #1:

Recommendation is for customers to upgrade to CallManager 5.1(1b). It is available at Software Download Cisco Unified CallManager 5.1 (registered customers only)

Option #2 :

To manually change MTM strings with the help from IBM field support, follow these steps:

  1. Check the Machine Type and Model from label on the Box, or by booting into BIOS setup utility when system comes up by pressing "F1".

  2. If the server has a Machine Type and Model (MTM) with following, then contact IBM field support to change the MTM strings to corresponding new value mentioned below:

Customers will need to contact IBM field support to manually change the Machine Type and Model (MTM) on the above mentioned servers to work around the issue. Once the IBM field support has changed the MTM strings, the server will be recognized as official and will be supported by CallManager 5.1(1a).
