Configuring the Controller

Configuring the SCSI Channels

You can change two channel configuration options for each channel:

✁Channel speed—You can change the channel speed for each SCSI channel on the controller. You can select Ultra or Ultra2. This is helpful if you are troubleshooting a problem on the channel or if you have legacy ultrawide disk drives.

Note: Ultra/Ultra2 SCSI is enabled by default. This means that for a single- ended bus, transfer rates are 40 MB/sec maximum; for an LVD bus, 80 MB/sec maximum. This Ultra SCSI setting only affects the device channel. Host SCSI channel rates are controlled by setting the host adapter.

✁SCSI ID assigned to each channel (initiator ID)—The controller assigns each of its SCSI channels one of the SCSI IDs (initiator IDs), leaving 15 SCSI IDs available for devices. You can change the SCSI ID assigned to each channel. You may need to do this if the default ID, 7, conflicts with a SEP ID. You can set the ID to any number between 0 and 15.

To configure the channel:

1From the System Menu, select Configuration Menu and press Enter. The Configuration Menu screen displays.

2Select Channel Configuration and press Enter. The Channel Configuration screen displays.
