This chapter tells you how to configure and install your internally mounted model 7000 or 2000XT DLT drive in a rack-mounted or standalone Origin Vault mass storage system. The DLT drive used with Origin2000 and Onyx2 rack and deskside products installs only in an Origin Vault's 5.25-inch option bay. The Origin Vault may be in the rack or ordered as an optional stand-alone deskside drive expansion tower. The Origin200 system's 5.25-inch option bay is the same as the Origin Vault's.
This chapter includes instructions on
If you need help with basic troubleshooting or maintenance procedures, go to Chapter 5, “DLT Drive Operation and Troubleshooting.” To set up your system's DLT drive as a network resource, refer to IRIX Admin: Peripheral Devices and the IRIX NetWorker guides (IRIX NetWorker Installation Guide, IRIX NetWorker Administrator's Guide, and the NetWorker for IRIX User's Guide).
The sled-mounted DLT drive is shipped in a single box. Inside, you should find the DLT drive (already mounted to the Origin Vault carrier adapter shell), a data cartridge, a cleaning cartridge, a CD, and this guide. Note that the Origin200 uses the same carrier shell as the Origin Vault.
After you unpack your DLT drive and its parts, make sure you have all the pieces shown in Figure 2-2. The power and SCSI cables at the rear of the unit may already be attached, but you should visually confirm this before installing the unit.
Each internally mounted DLT drive is assigned a default SCSI ID of 6 at the factory. If you install a DLT drive on a SCSI bus that supports other devices, use hinv to determine if any of them are using ID 6. If so, reconfigure either the DLT or the other drive to a different SCSI address (1-7).
If you need to remove the DLT drive from its carrier to reset the SCSI ID, obtain a #2 Phillips screwdriver and use the following steps:
Remove the two screws on the top and the two screws on the bottom of the carrier, as shown in Figure 2-3. Note the screw hole locations for replacement.
Gently slide the DLT drive forward approximately 2.5 inches (5 cm), until you can just access the SCSI ID jumper plug (see Figure 2-4).
Use the information on the following pages to set the SCSI ID to the desired number.
After setting or confirming the desired ID, reverse the process in step 1.
On the left side (near the front) of each internally mounted DLT drive is a 10-pin jumper plug that controls the SCSI ID of the DLT drive.
There are two jumper plugs; the SCSI jumpers install into the one that is nearest the back of the unit. See Figure 2-4 to identify the location of the jumper plugs. Do not place jumpers on any other plugs on the drive.
The SCSI ID selection jumpers are closest to the rear of the drive. Figure 2-5 shows what the pins on the SCSI ID connector represent.
 | Note: A jumper must always be placed on the Remote ID Present position for the host to recognize any ID selection on this connector. |
Figure 2-6 shows jumpering for SCSI IDs.
| Note: Never set the drive to SCSI ID zero; that ID is reserved specifically for the host SCSI controller. |
As a general rule, hard disk drives are usually numbered up from 1, and removable media drives numbered down from 7.
 | Caution: Use proper handling and storage procedures to minimize the loss of data and damage to equipment. Be sure to use standard precautions against electrostatic discharge when removing, storing, transporting, or replacing a DLT drive. |
The following sections provide specific information on how to install the Origin Vault or Origin200 internally-mounted DLT drive.
The 5.25-inch DLT drives are housed in a peripheral carrier in the vault or Origin200 host system. These installation procedures require a #2 Phillips screwdriver.
Each internally mounted DLT ships with the Origin Vault peripheral carrier already attached.
Remove any existing 5.25-inch drive bay carrier by following these steps:
Use a #2 Phillips screwdriver to unscrew the two screws that secure the front of the peripheral carrier to the Origin Vault or Origin200 chassis, as shown in Figure 2-7. Reserve the screws.
Grasp the handle of the peripheral carrier; the handle slides out about an inch.
Pull the carrier out of the bay, supporting it with your free hand (see Figure 2-7).
Retain the original drive carrier and cover plates if there is a possibility that you will need to install half-height drives later. The blanking plates snap into and out of place with tabs at the top and bottom (as in Figure 2-8).
Follow these instructions to install the new DLT drive:
Center the DLT and carrier in the 5.25-inch drive bay. The pull-out handle should be on the left for rackmount vaults and on the top for deskside tower models.
Slide the DLT and carrier assembly into the bay until the SCSI and power connectors are fully engaged (see Figure 2-9).
Use the #2 Phillips screwdriver to tighten the two screws that hold the carrier to the enclosure, then slide the handle all the way in (see Figure 2-10).
Depending on how many sled-mounted DLT drives you installed on the system, some configuration steps may be necessary. The hinv command can confirm if your system recognizes the new sled-mounted DLT drive(s). Chapter 5 provides sample hinv listings from DLT units.
If you installed only a DLT drive, it should be ready to use with your deskside or rackmount system. For information on backing up and restoring data using the new tape drive, see the Personal System Administration Guide.
Additional information is available in IRIX Admin: Peripheral Devices and the IRIX NetWorker guides.
If your DLT option shipped as a field upgrade, you may need to install software “patches” from the product release CD. Once you have installed the DLT drive, load the CD supplied with the tape drive. Check the information in the release notes to determine which patches to install for your system; install the patch(es) with the Inst utility, (see the IRIX Admin: Software Installation and Licensing manual).
Alternately, you can use the graphical user interface called Software Manager, (documented in the Personal System Administration Guide).
