Verifying Presence of the Cell Boards

Verifying Presence of the Cell Boards
To perform this activity, either connect to the Management Processor (MP) over the customer console or
connect the CE Tool (laptop) to the RS-232 Local port on the MP.
After logging in to the MP, verify that the MP detects the presence of all the cells installed in the server
cabinet. It is important for the MP to detect the cell boards. If it does not, the partitions will not boot.
To determine if the MP detects the cell boards:
1. At the MP prompt, enter cm.
This displays the Command Menu. Among other things, the Command Menu allows one to view or modify
the configuration and look at utilities controlled by the MP.
To look at a list of the commands available, enter he. You may have to press Enter to see more than one
screen of commands. Use the Page Up and Page Down keys to view the previous or next screen of
commands. To exit the Help Menu, enter q.
2. From the command prompt (MP:CM>), enter du.
The du command displays the MP Bus topology. A screen similar to the following is displayed:
Figure 4-17 The du Command Screen
There will be an asterisk (*) in the column marked MP.
3. Verify that there is an asterisk (*) for each of the cells installed in the server cabinet, by comparing what
is in the Cells column with the cells physically located inside the server cabinet.
Figure 4-17 shows that cells are installed in slots 0 and 1 in cabinet 0. In the server cabinet, there should
be cells physically located in slots 0 and 1.
