Chapter 3 Installing Mass Storage Devices • SCSI Device Selection o Use only HP LVD low-profile (1 inch) SCSI 3.5-inch hard disk drives in the Hot Swap drive slots. o Ensure the SCSI devices you install in Hot Swap slots do not have terminations installed. The Hot Swap backplane provides automatic termination for any unused slots. The HP Hot Swap SCSI drives come set without device ID or termination. Do not change these settings. o Do not use high voltage differential (HVD) SCSI devices on either of the SCSI channels. Using these devices will damage the backplane and render the SCSI drive slots inoperable. o The embedded dual-channel Ultra-160M SCSI controller includes connectors for SCSI channels A and B. o Channel A is used for connecting to the two SCSI backplane boards. The standard SCSI cable has one 68-pin, high-density connector for connecting to SCSI backplanes. o Channel B is used to control external mass storage devices, including an external backup tape drive. Channel B is connected to the external 68-pin SCSI connector on the rear of the Netserver. It can also be connected to internal backplanes and used for duplex mode. For information about duplexing, see "Duplexing Using Internal SCSI Channels" later in this chapter. • SCSI Drive Addressing o The SCSI drives in the Hot Swap slots are automatically assigned SCSI addresses according to their drive slot location-not on SCSI addresses you may set (see Figure 3-1). This is also the case if you are using a RAID controller board. Do not set SCSI ID software settings or jumpers on the SCSI drive's controller board. • SCSI Device Installation Order o The six Hot Swap drive slots support various SCSI HDD configurations. Start from the top left side when adding Hot Swap SCSI hard drives in the HP Netserver. • Filler Panels o Ensure that the empty SCSI HDD slots in the chassis have filler panels inserted before powering on the Netserver to ensure proper airflow. See Figure 3-2. 18

the Hot Swap drive slots.
o

o
Do not use high voltage differential (HVD) SCSI devices on either of the
SCSI channels. Using these devices will damage the backplane and
render the SCSI drive slots inoperable.
o
The embedded dual-channel Ultra-160M SCSI controller includes
connectors for SCSI channels A and B.
o
Channel A is used for connecting to the two SCSI backplane boards. The
standard SCSI cable has one 68-pin, high-density connector for
connecting to SCSI backplanes.
o
Channel B is used to control external mass storage devices, including an
external backup tape drive. Channel B is connected to the external 68-pin
SCSI connector on the rear of the Netserver. It can also be connected to
internal backplanes and used for duplex mode. For information about
duplexing, see “Duplexing Using Internal SCSI Channels” later in this
chapter.

o
The SCSI drives in the Hot Swap slots are automatically assigned SCSI
addresses according to their drive slot location-not on SCSI addresses you
may set (see Figure 3-1). This is also the case if you are using a RAID
controller board. Do not set SCSI ID software settings or jumpers on the
SCSI drive’s controller board.
•
SCSI Device Installation Order
o
The six Hot Swap drive slots support various SCSI HDD configurations.
Start from the top left side when adding Hot Swap SCSI hard drives in the
HP Netserver.
•
Filler Panels
o
Ensure that the empty SCSI HDD slots in the chassis have filler panels
inserted before powering on the Netserver to ensure proper airflow. See
Figure 3-2.
