Mounting Holes for Internal DAT24 Drive in 5. 25-inch Configuration (with mounting brackets) 16 Installation Installing an Internal DAT24 Drive Connecting Power and Interface Cables Attach the power and SCSI interface cables to the appropriate connectors on the back of the drive. Figure 6 on page 17 shows the locations of these connections. Connecting the SCSI Interface Cable Turn off all power to the drive and host computer. Attach the SCSI cable, making sure to align pin 1 on the cable with pin 1 on the drive. Pin 1 on the SCSI connector is to your right as you look at the back of the drive (see Figure 6). Your SCSI cable should have pin 1 highlighted by a colored stripe. Connecting the Power Cable Attach a 4-pin power connector from the system power supply to the connector on the back of the drive. The recommended 4-pin power connector for the internal drive is an AMP 1-48024-0 housing with AMP 60617-1 pins or equivalent. 4-pin power connector SCSI pin 1 SCSI connector Figure 6. Locations of SCSI Interface and Power Connectors on the Internal Drive 17 Installation Installing the Desktop DAT24 Drive Installing the Desktop DAT24 Drive The desktop DAT24 tape drive is a compact external unit that connects to the host computer as a turnkey subsystem. Registering it ensures that you will receive the latest information about the drive, as well as other product, service, and support information. For your convenience, you can register the DAT24 through our Web site at http://register. certance. com. Configuring the Desktop DAT24 Drive The following is the default configuration for desktop DAT24 tape drive: · · · · · Drive reads and writes both MRS and non-MRS 4-mm media. Termination power is supplied to the SCSI bus. NOTE: Some configuration settings can be changed using the SCSI Mode Select command. SCSI command information for Certance DAT drives is provided in the product description manual. Setting the SCSI ID Be sure the drive is turned off; then set the SCSI ID for the drive using the push-button switch on the back of the external drive. Figure 7 on page 19 shows this switch, as well as the two SCSI interface connectors, the on/off switch, and the power-cord connector. NOTE: The drive must be restarted, or a SCSI bus reset must be issued to have the new SCSI ID take effect. 18 Installation Installing the Desktop DAT24 Drive Push-button Switch ON/OFF Switch 6 SCSI Connectors Figure 7. Rear Panel of the Desktop Drive Power Connector Connecting the SCSI Interface Cable The desktop DAT24 tape drive has two SCSI connectors to allow daisy chaining (see Figure 7 on page 19. You can use either connector to attach the drive to the host computer or to another SCSI device. NOTE: Turn off all power before connecting or disconnecting SCSI cables or terminating plugs. If the desktop drive is the last device or the only device in a SCSI chain, install a terminating plug on the unused SCSI connector. Figure 8 on page 19 shows two SCSI termination examples. External SCSI device (termination enabled) External SCSI device (termination enabled) External SCSI device External SCSI device SCSI Controller Internal SCSI device SCSI Controller (termination enabled) Internal SCSI device (termination enabled) Example 1: SCSI termination in a system that has only external SCSI devices. Example 2: SCSI termination in a system that has both internal and external SCSI devices. Figure 8. SCSI Termination Examples Connecting the Power Cord Attach the power cord securely to the power connector on the back of the drive. Figure 7 on page 19 shows the location of the power connector. 19 3 Operation Introduction This chapter describes how to use your internal or external DAT24 tape drive. Topics covered in this chapter are: · · · · "Loading a Cartridge" on page 20 "Unloading a Cartridge" on page 21 "Initializing a Blank DAT Cartridge" on page 21 "DAT Cartridge Compatibility" on page 22 Caution. To avoid data loss, clean the drive heads using a DDS head-cleaning cartridge after every 25 hours of read/write operation, or whenever the green cartridge-status LED flashes during operation. See page 23 for cleaning procedure. Loading a Cartridge The DAT24 tape drive has a front-loading cartridge bay for easy operation. Figure 9 on page 20 shows a cartridge being inserted into a 3. 5-inch internal drive. [. . . ] Alternatively, Irix 5. 3 and later detect the changes made and automatically rebuild the kernel the next time the system boots. Once the new Kernel is built you will need to reboot the system again to bring the changes into effect. 2. 31 UNIX Settings Checking the Drives Inquiry String Configuring for the HP-UX Workstation Environment Troubleshooting Installation Problems on the SGI Platform You can configure the DAT24 tape drive to return different inquiry strings. Consequently, before making the changes described in this chapter, it may be useful to check the drive's inquiry string using the mt command. The following example retrieves the inquiry string and other status data from a DAT24 tape drive on SCSI bus 1, ID 4. mt -f /dev/rmt/tps1d4 status System Interchange Problems If the following error appears when trying to restore a cpio archive from another system, a mistake has been made in the installation sequence above: Byte swapped Data - re-try with correct device If this error is encountered, it is probably caused by incorrect setup, as described above, Check and verify the correct modifications were made to /var/sysgen/master. d/scsi.
