IBM Tape Diagnostic Tool A script sgen_solaris_conf.sh is included in the ITDT-SE package. This script allows the user to configure the sgen generic SCSI driver that is shipped with Sun Solaris. ITDT-SE requires that the sgen device driver is configured so that the devices you want to work with can be found. Note: For system security reasons, always reset the sgen device driver settings after you finish working with ITDT-SE, using the sgen_solaris_conf.sh script. To configure the sgen driver, start the sgen_solaris_conf.sh script with root access. The following command line options are available on the SGEN driver configuration screen: v 1) Check driver: This option checks if the driver /kernel/drv/sgen is available. v 2) List driver settings: This option shows the current activated devices. v 3) New driver configuration: This option displays the screen that is used to create a new driver configuration (see Step 2). v 4) Stop sgen driver: This option stops the driver (that is, rem_drv sgen). v 5) Start sgen driver: This option stops and starts the sgen driver. v 6) Exit program: This option closes the shell script. 2. Enter option 3) to create a new driver configuration: The following command line options are available on the New Configuration screen. Use these options to configure the sgen driver: v 1) List targets: This option shows the targets in current configuration. v 2) Define device types: This option defines drive and changer types. v 3) or 5) Add target(s): This option adds targets to the list. Note: Option 3 allows for the addition of individual devices one at a time, Option 5 allows for the addition of a range of devices, eliminating the need to add a large number of devices one by one. v 4) or 6) Remove target(s): This option removes targets from the list. Note: Option 4 allows for the removal of individual devices one at a time, Option 6 allows for the removal of a range of devices, eliminating the need to remove a large number of devices one by one. v 7) Save configuration: This option saves the modifications. v 8) Back to Main Menu: This option returns to the main menu. 3. After the sgen driver is configured, enter command line option 8 to go back to the main menu. 4. On the SGEN driver configuration screen enter command line option 5). This option starts the sgen driver, new devices are found using the definitions performed in Step 2. 5. After the new devices are found, enter option 6) to exit the sgen_solaris_conf.sh script. Note: For Fibre Channel Host Bus Adapters (HBAs), special handling is required. Attached devices need to be configured with their WWPN in the sgen.conf file. This task needs to be done manually, it is not performed by using the sgen_solaris_conf.sh script. 268 IBM Tape Device Drivers Installation and User's Guide
