Installing and Configuring

Installing an Optional Backup Tape Drive

The optional HP SureStore DAT 24i backup tape drive is a single-ended device and may slow down the disk access time for the Ultra-160 SCSI drives. A second SCSI controller board may be required to separately control the backup tape drive.

1.If the Server is already installed and operating, power-down the Server. Refer to Chapter 1, “Controls and Indicators.”

2.Disconnect the power cables and any external cables connected to the Server. If necessary, label each one to expedite re-assembly.

3.Remove the left side cover from the Server.

Refer to “Opening and Closing the HP Server” earlier in this chapter.

4.Remove the upper front bezel.

Refer to “Opening and Closing the HP Server” earlier in this chapter.

5.Press in on both tab latches to release the third drive tray and pull it out at the same time. See Figure 3-11.

6.Remove the RFI shield from the third drive tray. See Figure 3-11.

7.Ensure that the backup tape drive is not terminated and ensure that the SCSI ID jumper is set for address = ID 3 on the tape drive.

The optional HP SureStore DAT 24i backup tape drive is shipped with the default setting of SCSI address = ID 3. Refer to the documentation provided with the tape drive.

8. Install the backup tape drive, as described below:

a. Place it into the tray and use the screws provided to secure it to the tray. See Figure 3-11.

The optional HP SureStore DAT 24i backup tape drive is a single-ended drive and normally comes with the 5¼ inch mounting brackets installed on the tape drive. If not, follow the instructions provided with the tape drive to connect the 5¼-inch mounting brackets to the tape drive, before installing the tape drive into the third drive tray.

b. Insert the backup tape drive mounted in the tray into the third shelf.

The tabs should snap into place when the third drive tray is pushed all of the way into the third shelf.

CAUTION Install and remove connectors carefully, and avoid displacing any of the pins.

9.Connect the SCSI data and power cables to the rear of the back up tape drive.

The SCSI data and power cables for the tape drive should already be routed to the tape drive. If not locate the free SCSI and power connectors and route to the tape drive.

NOTE

The slower speed of the tape drive may slow disk access time for the Ultra-160 SCSI

 

drives. You may need to install a second SCSI controller board to control the backup tape

 

drive separately from the Ultra-160 SCSI drives. You may use the internal SCSI cable

 

provided with the second SCSI controller board to connect to the tape drive.

 

 

10.Replace the upper bezel and the left side cover.

11.Replace the external cables, power cord, and then restore power to the Server.

The SCSISelect Utility automatically detects the new SCSI backup tape drive, but you should check the SCSISelect settings and make changes as necessary.
