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.
