Using Multiple or Multi-Channel SCSI Controllers
The following guidelines apply if you configure your server using multiple
or multi-channel SCSI controllers.
•
The SCSI controller with the lowest BIOS address is identified by
the server as the “primary” SCSI controller. If you are loading the
operating system from a SCSI hard disk drive, this primary or boot
drive must be connected to the primary SCSI controller. The SCSI
address of the primary SCSI hard disk drive must be set to the
lowest SCSI address connected to the SCSI controller.
•
To improve server performance, you might want to distribute the
SCSI devices across the SCSI controllers. When arranging SCSI
devices, make sure each device connected to a SCSI controller is
assigned a unique SCSI address.
•
Each operating system has different limitations regarding the num-
ber of SCSI controllers that are supported. Refer to your operating
system documentation for additional information.
•
SCSI IDs on one channel do not interfere with the IDs on another
channel. This applies when using two SCSI controllers that imple-
ment a different bus as well as dual channels on a single SCSI
controller.
