Finding Existing SCSI
Devices and Controllers 3
Each SCSI device attached to a host must have a unique SCSI address.
The first step in configuring the UNIX environment is to determine the
addresses of all SCSI devices to verify that each has a unique address.
Configuring Sun UNIX Environments
This subsection provides procedures for configuring the following Sun
UNIX operating system environments:
• Solaris 2.4, 2.5 and 2.6
• Solaris 7, 8, 9 and 10
Controller Type Maximum Transfer Rate
Ultra 320 SCSI 320 Mbytes per second, most preferred
Ultra 3 SCSI 160 Mbytes per second
Wide Ultra2 SCSI 80 Mbytes per second, compatible
Note: SCSI ID 7 is almost always dedicated to the SCSI controller.
Never configure the LTO-3 Half-Height Tape Drive for ID 7
unless you are absolutely sure that the controller is not
assigned ID 7.
