2-8 System GuideBackup and RestoreTo stop the scrolling display, press . When promptedto discontinue the display, enter y.Checking the tape driveIf the System backup or recovery script generates an errormessage indicating that the tape drive cannot be found, performthe following steps:1. If the Xerox FreeFlow Print Server is running, follow theprocedures in your customer documentation to shut down andpower off the controller. If the system displays a # prompt,enter halt. When the OK prompt is displayed, power off thecontroller.2. Power off the tape drive.3. Ensure that the SCSI cable connecting the tape drive to thecontroller is securely connected. If the tape drive is yoursystem's only external SCSI device, there should be only oneSCSI cable connected to the tape drive, and it should beconnected to the In connector.If there are other SCSI devices (for example, external harddrives), ensure that the cable connected to the In connector leadsback towards the controller (even if there is another devicebetween the tape drive and the controller). Also verify that thereare no bent pins on the connector.1. If the tape drive is an older unit (for example, an 8mmDocuTech tape drive) with a 50-pin SCSI connector, aterminator must be installed on the Out connector if the tapedrive is the last device on the SCSI chain.NOTE: The 50-pin connector is approximately 1.5 inches wide.Newer tape devices have a 68-pin Ultra-SCSI connector, which is1.75 inches wide.NOTE: The 4mm and QIC tape drives are all Ultra-SCSI devices.These are auto-terminating so no external terminator is needed.2. Check the SCSI ID selector and ensure that it is not set to 0, 1,3 or 6. These settings could possibly conflict with internal SCSIdevices on some controller types. If there are other externaldevices, ensure that no two devices are set to the same SCSIID.NOTE: The SCSI device ID selector is a small window with twosmall buttons, located on the back of the drive. Press the buttonsto change the value, if necessary.3. Ensure that the tape inserted in the drive is a regular tape andnot a cleaning tape.4. Power on the tape drive, and wait 10 seconds.5. Power on the controller.
