IBM 887022X Maintenance Manual - Page 27

The following gives information about memory mirroring: - The hot-add memory feature allows you to add DIMMs without turning off the server. This feature is supported only in those servers using Windows Server 2003 Enterprise or Datacenter editions. - To use the hot-add memory feature memory mirroring must be Disabled. - To use the hot-replace memory feature memory mirroring must be Enabled. - CPU Options Select this choice to specify whether the serial number in the microprocessor is to be readable. You can also disable the microprocessor cache or set it to use the write-back or write-through method. Write-back caching generally provides better system performance. - PCI Bus Control Select this choice to view and set interrupts for PCI devices and to configure the master-latency-timer value for the server. - Integrated System Management Processor Settings Select this choice to enable or disable the Reboot on System NMI option on the menu. If you enable this option, the server will automatically restart 60 seconds after the service processor issues a nonmaskable interrupt (NMI) to the server. If you disable this option, the server will not restart. Enable is the default setting. - Scalability Port Configuration Select this choice to view a summary of the current scalability port configurations. Note: Scalability ports are called SMP Expansion Ports in this publication. - Scalable Partition Settings Select this choice to view a summary of current scalable partition settings and to configure or delete partition settings. Notes: 1. Partition settings are called partition descriptors in some IBM documentation. 2. See "Scalable partitions" on page 140 for more information on creating, deleting, and configuring scalable partitions. v Error Logs Select this choice to view or clear error logs. Note: When troubleshooting problems with PCI-X slots, you will notice that the error logs report the PCI-X busses numerically. The numerical assignment will change depending on your configuration. - POST Error Log Select this choice to view the three most recent error codes and messages that were generated during POST. Select Clear error logs to clear the POST error log. - System Event/Error Log Select this choice to view the System Event/Error log, which contains all system error and warning messages that have been generated. Use the arrow keys to move between pages in the log. Select Clear error logs to clear the System Event/Error log. v Save Settings Select this choice to save the changes you have made in the settings.
