TABLE D-2
SCSI Device
Internal disk: lower position (first internal disk drive)
Internal disk: upper position (second internal disk drive)
External disk drives
External tape drives
External CD-ROM drive
* Assign the external disk drive to SCSI address 1 only if a single disk drive is
installed.
Note – Do not change the physical position of the internal drive. Doing so may
cause an operating system initialization failure.
The internal disk drives are assigned an SCSI address number based on the drive
bay disk drive position. The lower drive bay disk drive position is automatically
assigned SCSI address 3. The upper drive bay disk drive position is assigned SCSI
address 1. These addresses cannot be changed. With the Solaris 2.3 operating
environment (and later operating environment releases), any SCSI device (disk, tape,
CD-ROM, etc.) may be assigned any SCSI address from 0 to 6.
Note – SCSI address 7 is reserved for the SCSI processor of the computer system or
the SCSI host adapter card.
