Note: If you install a PCI RAID adapter to configure and manage the internal hot-swap drives, you must move the SCSI cable from the system-board SCSI connector to an internal channel connector on the RAID adapter. See “Cabling example for the ServeRAID adapter” on page 56 for additional information.

SCSI cabling requirements

If you plan to attach external SCSI devices, you must order additional SCSI cables. To select and order the correct cables for use with external devices, contact your IBM reseller or IBM marketing representative.

For information about the maximum length of SCSI cable between the terminated ends of the cable, refer to the ANSI SCSI standards. Adhering to these standards will help ensure that the server operates properly.

Setting SCSI IDs

Each SCSI device connected to a SCSI controller must have a unique SCSI ID. This ID enables the SCSI controller to identify the device and ensure that different devices on the same SCSI channel do not attempt to transfer data simultaneously. SCSI devices that are connected to different SCSI channels can have duplicate SCSI IDs. The following table lists the SCSI IDs for devices that are connected to one channel. Note that the hot-swap hard disk drive bay numbers are from bottom to top.

Table 17. SCSI IDs for hot-swap hard disk drives and backplanes

Standard

Optional

 

 

Drive bay 1: SCSI ID 0

Drive bay 4: SCSI ID 12

 

 

Drive bay 2: SCSI ID 1

Drive bay 5: SCSI ID 13

 

 

Drive bay 3: SCSI ID 2

Drive bay 6: SCSI ID 14

 

 

Backplane: SCSI ID 8

Backplane: SCSI ID 9

 

 

The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive bays. However, when you attach a SCSI device to the external SCSI connector, you must set a unique ID for the device. Refer to the information that is provided with the device for instructions to set its SCSI ID.
