Preinstallation Planning
Manual No. 775012 2-5
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.
