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 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 termination power on the drives.
Refer to the drive manual for specific information about drive configuration
settings.
☛
Note
The supported SCSI drive types include Ultra2 SCSI
with LVD as well as the following single-ended SCSI
types: SCSI-1, Fast SCSI, Wide Fast SCSI, Ultra
SCSI, Wide Ultra SCSI, and Wide Ultra2 SCSI.
m Caution
If wide drives are to be connected to a narrow SCSI
connector (by a 68-pin to 50-pin adapter), the 8-bit
bus width parameter must be set first, using RAID
EzAssist.
Instructions on how to force the 8-bit bus width are in
the RAID EzAssist Configuration Utility User
Reference Guide (P/N 775029), under “Advanced
Parameters.”
