Linux Device Driver (lin_tape) Verifying Installation and Updating Run the following command to verify the lin_tape device driver version if there is at least one tape device attached to the system: IBMtapeutil -f /dev/IBMtape0 qryversion Note: This is performed using tape diagnostic and utility functions. Configuring Tape and Medium Changer Devices on Intel-Compatible Systems If you have not physically attached your tape and medium changer devices to your Linux server, perform the following steps: 1. Halt the Linux server. 2. Power down the Linux server. 3. Physically attach the tape and medium changers to the host bus adapter cards. Consult your hardware documentation for details. 4. Power on the tape and medium changer devices. Verify that they have completed the initialization process. 5. Power on and boot the Linux server. Note: Hot plugging SCSI devices while the Linux server is running may cause hardware damage. After the driver software is installed and a tape device is connected to the adapter, the device can be configured and made available for use. Access to the device is not provided until the device is configured. If your system is attached to an IBM 3583 Tape Library with the integrated router, before installing the Qlogic driver, set the host type of the router to solaris and make sure that the logical unit numbers of the control unit, medium changer, and the connected tape drives are contiguous (otherwise, the Qlogic device driver does not recognize all of the attached devices). To view the LUNs of attached devices, log onto the router and use the fcShowDevs command. If the LUNs are not contiguous, use the mapCompressDatabase command to delete the invalid LUNs and make the valid LUNs contiguous. If you have the StorWatch Specialist installed, you can use the Specialist to do this configuration. For further information about the StorWatch Specialist, refer to the IBM Storage Area Network Data Gateway Installation and User's Guide. You can download the guide from the Web at: http://www.storage.ibm.com/hardsoft/products/sangateway/support/cdr/ Document/sdgdoc.htm When you run the lin_tape kernel module, it creates special files in the /dev directory. To configure the tape devices, use the IBMtapeutil application program. Choose Query/Set Tape Parameters in the menu. Note: This is performed using tape diagnostic and utility functions. Chapter 5.
