DOCUSP 3.74 Testing the backup tape 5-6 Label the next cassette "Vol 2," insert it into the tape drive, then enter yes. This message set is repeated for as many tapes as required to complete the backup. IMPORTANT: Proper labeling of the tape is essential to a successful recovery. As the system requests additional tape cartridges, be sure to label the tapes in the correct sequence (for example, Vol #1, Vol #2, etc.). If you insert the tapes in the wrong order during the recovery, the restoration fails. NOTE: Due to the current DocuSP licensing protection scheme, tapes can be restored only to the system from which they were backed up. In other words, tapes from one system cannot be used to "clone" another system. Any attempt to do this will invalidate the DocuSP license, and a full reloading of software will be required to make the system operational. If you have multiple printing systems, it is recommended that tapes be labeled with the hostname of the system to reduce the possibility of restoring to the wrong system. The following procedure enables you to check if the backup tape contains valid data. 1. Ensure that the tape drive is connected and powered on. Insert the backup tape in the tape drive. If the backup required more than one cassette, make sure that the first tape (Vol 1) is inserted. 2. Open a Terminal window and logon as root user. 3. Enter mt -f /dev/rmt/0 status to check the tape drive status. The system returns a message indicating the type of tape drive. If the system generates the error message /dev/rmt/0: no such file or directory, enter mt -f /dev/rmt/1 status. If the error message is displayed again, repeat steps 1 through 3 of the "Checking the tape drive" procedure, described later in this chapter. If the problem persists, call for service. 4. When the tape drive location has been verified, enter the following command: ufsrestore tvf /dev/rmt/xbn" where x is either 0 or 1, depending on the value that you used in step 3. After a few seconds, the system starts displaying the contents of the tape cassette. To stop the scrolling display, press . When prompted to discontinue the display, enter y.
