Preinstallation Planning

SCSI Drive Preparation

Prepare the drives for installation as follows:

•Remove any terminators attached to the drive or set any drive termination jumpers to the disabled position.

•Set the SCSI addresses on the drives.

☛Note

Each drive on a channel must have a unique ID chosen from 0 through 6 or 8 through 15. ID 7 cannot be used as a drive ID because it is reserved for the controller.

•Enable term power on the drives.

Refer to the drive manual for specific information about drive configuration settings.

To get best performance from the controller, the SCSI drives should be equally distributed across the SCSI channels, and the controller’s data transfer rate should be set to the optimum rate for the drives being used.

Mixing Narrow and Wide SCSI Devices

Narrow and Wide SCSI devices must not be mixed on a single channel. If mixing Narrow and Wide SCSI devices is desired, at least one channel must be dedicated to Narrow SCSI, and at least one channel must be dedicated to Wide SCSI.
