•
The SCSI ID for each hot-plug hard drive is set automatically to the next sequential ID number in a
series beginning with ID0.
•
If only one SCSI hard drive is used, install it in the bay with the lowest number.
•
Hot-plug hard drives must be either Wide Ultra2, Ultra3, or Ultra320 SCSI types. Mixing these types
with other drive standards degrades the overall performance of the drive subsystem.
•
Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
SCSI IDs
The server supports single- or dual-channel hard drive configurations. The single-channel configuration
(simplex) supports up to six hard drives on one channel. The dual-channel configuration (duplex) supports
two hard drives on one channel (SCSI IDs 0 and 1) and up to four hard drives on the other channel (SCSI
IDs 2 through 5).
The SCSI IDs for both simplex and duplex configurations are illustrated. Always populate hard drive bays
starting with the lowest SCSI ID.
Removing a SCSI hard drive blank
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless all bays
are populated with either a component or a blank.
