If you needed to add a device driver, you will also need to create a new kernel and (eventually) reboot the system. Select from the menu on the Create a New Kernel screen whether you want to create the new kernel now, later, or cancel the proposed modications. (Make sure your choice has an asterisk placed by it, by pressing Return while that line is highlighted. ) Choose OK to conrm your choice of action. NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNN NNNNNNNN 9. You will next be given a choice of whether to install the new kernel now or later. If you move the kernel into place now, the system will also reboot. If you choose to do it later, you can then move the new kernel, Configuring HP-UX for Printers and Drives 4-25 FINAL TRIM SIZE : 7. 0 in x 8. 5 in /etc/conf/dfile. SAM to /hp-ux and reboot. You should also move /etc/conf/dfile. SAM to /etc/conf/dfile at the same time. If you reboot, the old kernel will be backed up as /SYSBCKUP. Exit SAM, if you have not already done so. Note If you are modifying a cluster client's kernel, its kernel is not backed up, since /SYSBCKUP is used exclusively for the cluster server's kernel. 4 Your system is now running the added driver for SCSI DDS tape drive. You are ready to use the drive to load a tape into your system. Testing Your Installation Note that a write-protect tab on the cassette allows you to protect data from being over-written. You will need to make sure that the tab is moved to the \writable" position in order for it to serve as a back up medium. A simple test to make certain that everything has been installed satisfactorily is to load a tape in the drive, wait for the \busy" light to stop blinking, and execute the ioscan command: /etc/ioscan The LED on the drive should icker brie y. If the command completes successfully, a listing of your devices, including the tape hardware address, name and status will be displayed, indicating that it is installed correctly. Note that the command may fail with a busy error if the command is executed before the tape has completed loading. 4-26 Configuring HP-UX for Printers and Drives FINAL TRIM SIZE : 7. 0 in x 8. 5 in DDS Tape Drive LED Indicators Two LED indicators on the drive's front panel indicate several operational and test states. The following tables show the LED combinations and explains what they indicate.

DDS Tape Drive LED State Codes 4 Caution Indicator The DDS drive continually monitors the number of errors it has to correct when reading or writing a tape. This information is presented to the user through the Caution Indicator (see above chart). A caution indication has two common meanings: The tape heads need cleaning. The tape itself is approaching the end of its useful life. 4-28 Configuring HP-UX for Printers and Drives FINAL TRIM SIZE : 7. 0 in x 8. 5 in Maximum Usage of DDS Cassettes Under optimal environmental conditions (50% relative humidity, 22 C), Hewlett-Packard DDS cassettes are currently specied to 2000 passes over any part of the tape. In operational terms, this can be translated into approximately 200 to 300 backup operations. This takes into account that, during a backup, an area of tape may have several passes because streaming cannot be maintained, or because the backup software requires that certain areas of the tape are accessed frequently. Under certain conditions, the recommended number of backup operations needs to be reduced. [. . . ] The system is only accessible to the current system administrator (root). This mode is brought about by execution of shutdown(1). Also called single-user mode. Glossary-9 FINAL TRIM SIZE : 7. 0 in x 8. 5 in Glossary SPU System Processing Unit.
