Hot-plug SCSI hard drive options
When adding SCSI hard drives to the server, observe the following general guidelines:
• A maximum of 14 SCSI devices per channel can be added.
• Each SCSI drive must have a unique ID. The system automatically sets all SCSI IDs.
• 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).
