Backup and RestoreSystem Guide 2-15The file restore.log is used to record recovery activities. It isin the root directory of the DSPERU diskette. Please note thatthis diskette, and therefore the log is only readable on a UNIXsystem. The first line of the log, contains the time and datethe recovery was initiated. To prevent the log from beingoverwritten the next time a recovery is performed, renamethe log. You should give it a name that is somehow relatedthe date that the recovery was made (for example,restore040402.log).Checking the tape driveIf the backup or recovery script generates an error messageindicating that the tape drive cannot be found, perform thefollowing steps:1. If DocuSP is running, follow the procedures in yourcustomer documentation to shut down and power off thecontroller. 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 tothe controller is securely connected. If the tape drive isyour systems only external SCSI device, there should beonly one SCSI cable connected to the tape drive, and itshould be connected to the In connector.If there are other SCSI devices (for example, external harddrives), ensure that the cable connected to the In connectorleads back towards the controller (even if there is anotherdevice between the tape drive and the controller). Also verifythat there are 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 thetape drive is the last device on the SCSI chain.NOTE: The 50-pin connector is approximately 1.5 incheswide. Newer tape devices have a 68-pin Ultra-SCSIconnector, which is 1.75 inches wide.NOTE: The 4mm and QIC tape drives are all Ultra-SCSIdevices. These are auto-terminating so no externalterminator is needed.
