between stand-alone and multinode mode” on page 231) to boot the systems in
stand-alone mode after a reboot.
After the scalability mode is changed to stand-alone mode, the serial numbers of
each system is selectable, as shown in Figure 4-33.

If you add a check mark in one of the serial number (SN) boxes, then click Reset ,
the server immediately resets. The secondary server logs an error and reboots
unexpectedly several seconds later.
How to identify the problem
Check the RSA II event logs at each node as described in 4.9.1, “Problem with
merging if prerequisites were met” on page 237
if, for example, a CPU error
occurred that is not linked to having the wrong type of CPU. See Example 4-8.
Example 4-8 RSA II event log
1 Err SERVPROC 04/16/08, 22:02:03 Resetting system due to an unrecoverable error
2 Err SERVPROC 04/16/08, 22:02:03 Machine check asserted - SPINT, North Bridge
Solution and workaround
This problem is reported to IBM development. Newer RSA II firmware prevents
the serial number of any node from being selectable.
Do not reboot one system in stand-alone mode after the scalability mode was
changed to stand-alone mode and all other systems are still running in the
operating system.
