Verifying Presence of the Cell Boards
To perform this activity, either connect to the MP using a console, or connect the CE Tool (laptop) to the
RS-232 Local port on the MP/SCSI Core I/O.
After logging in to the MP, verify that the MP detects the presence of all the cells installed in the 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. The Command Menu enables viewing or modifying the configuration
and viewing the utilities controlled by the MP.
To view a list of the commands available, enter he. 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 4-12
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 cabinet, by comparing what is in
the Cells column with the cells physically located inside the cabinet.
Figure 4-12 shows that cells are installed in slots 0 and 1. In the cabinet, cells should be physically
located in slots 0 and 1.
