HP Integrity rx8620 Server User Service Guide

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
do not boot.
To determine if the MP detects the cell boards, follow these steps:
1. At the MP prompt, enter cm.
This displays the Command Menu. Among other things, the Command Menu enables you
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 displays:
Figure 4-17 The du Command Screen
There is 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.
Configuring AC Line Status
The MP utilities can detect if power is applied to each of the AC input cords for the server, by
sampling the status of the bulk power supplies. During installation, use the following procedure
to check the configuration for the AC line status and configure it to match the customer’s
environment.
Selecting the Grid A only option directs the MP utilities to sense locations A0 and A1 for active
power. Selecting the Grid B only option directs the MP utilities to sense locations B0 and B1 for
active power. Selecting the Grids A & B option directs the MP utilities to sense active power at
locations A0-A1-B0-B1.
