Solaris Device Driver (IBMtape) 2. When adding support for a new device, ensure that the target and LUN values in the configuration file stanza match the target and LUN settings of the IBM device. Refer to "Configuration Parameters" on page 139 for more information about the IBMtape.conf configuration file. 3. Shut down and power Off the host system. 4. Plug the new device into the SCSI bus or unplug the existing device from the bus. Pay particular attention to proper SCSI cabling and termination. 5. Power On and start the host system. Notes: a. It is possible to reinitialize the IBMtape device driver without restarting the system. This is done by first unloading the device driver, then reloading the device driver into kernel memory. b. For the version of IBMtape.4.0.9.2 and later, the TMD daemon has to be stopped by running the /opt/IBMtape/tmd -s command to unload the IBMtape driver from the kernel. Running the /opt/IBMtape/tmd command restarts the daemon afterwards to reload the device driver. The commands to unload the device driver are: % /opt/IBMtape/tmd -s for IBMtape.4.0.9.2 and later % /usr/sbin/rem_drv IBMtape The commands to reload the device driver are: % /usr/sbin/add_drv -m '* 0666 bin bin' IBMtape % /opt/IBMtape/tmd for IBMtape.4.0.9.2 and later When the IBMtape device driver is reloaded, it reads the IBMtape.conf file and acknowledge changes made in the file. This method can be used to modify configuration parameters. Note: It is strongly suggested that the host system and all devices attached to the SCSI bus be powered Off before adding or removing devices from the SCSI bus. Hot plugging SCSI devices can cause hardware damage and disruption of reliable system operation. Deconfiguring Tape Devices In some special situations, the user cannot modify IBMtape.conf to deconfigure some tape devices with IBMtape driver, when more than one device is configured with the same target address, or the tape devices are attached on the FC or SAS HBA running with Sun HBA driver. In IBMtape.4.1.9.2 and later, a configuration parameter defined exclude_dev_list is introduced to allow users to exclude some devices from the configuration with IBMtape. Deconfigure the tape device using the following: 1. Add the entry of "exclude_dev_list" in IBMtape.conf located in /usr/kernel/drv. exclude_dev_list="sn1,sn2,sn3,..." ; Where: "sn" is the serial number of the excluded device, 10-characters long for LTO drive, 12-characters long for 359x drive and 16-characters long for changer. The serial number can be found running the following command: /opt/IBMtape/tapelist -l 2. Re-install IBMtape driver or reboot the system to allow IBMtape update the configuration. Chapter 6.
