IBM 8870 CPU Options, PCI Slot/Device Information, ASM Settings, Scalability Port Configuration

The following information applies to memory mirroring:

-The hot-add memory feature allows you to add DIMMs without turning off the server. This feature is supported only in 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, to enable or disable hyperthreading technology for all installed microprocessors, or to 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 Slot/Device Information

Select this choice to view the properties and settings for adapters installed in the PCI slots.

–ASM 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. (This choice appears on the Advanced Setup menu when cables are connected to the SMP Expansion Ports.)

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 “Configuring scalable partitions” on page 22″ 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.
