Cluster Configuration for BusLogic Controllers

• Microsoft Windows NT Server, Enterprise Edition version 4.0 - Microsoft Cluster Server

SUMMARY

Some cluster configurations may use BusLogic SCSI host adapters. It is important with any cluster configuration to ensure proper settings on each adapter attached to the shared SCSI bus. Administrators may find the need to use the adapter's firmware setup utility to configure specific options.

MORE INFORMATION

Some BusLogic controllers provide the ability to access the firmware setup by pressing the CTRL+B key sequence immediately following the adapter's initialization banner.

After activating the firmware setup program, there are several different configuration menus to choose from. To configure the adapter for use with a shared SCSI bus, use the Advanced configuration menu to disable SCSI BUS RESETS. This prevents the adapter from issuing a reset command to the shared bus while the other controller on the shared bus may be working with devices. Additionally, because the shared SCSI bus is not used to start the operating system, consider setting the controller BIOS to disabled.

Use the Adapter configuration menu to specify the SCSI ID for the host adapter. On the shared SCSI bus, one adapter will typically use ID 6 and the other ID 7. It is very important not to allow both adapters to use the same ID. Additionally, if your system provides termination through the cabling or external terminators, make sure to disable the termination feature on the adapter so as to avoid double termination.

Additional information about these options and proper configuration for your hardware may be supplied by the vendor. For best results, consult with your hardware vendor for additional details pertaining to your hardware.
