HP-UX Device Driver (ATDD) configured devices are to use the device driver configuration defaults, it is not necessary to create a configuration file before installing the driver for ATDD. The Drive Configuration File is required if: v You are running a level of ATDD before level 1.7.1.0 on HP-UX 11.0. v You do not use the device driver configuration defaults. If you do not need to create a Drive Configuration File, skip to the instructions in "Power Off the Tape Drives" on page 61. If you do need to create a Drive Configuration File, consult the following instructions. The configuration file is named sbin/init.d/atdd and has the following syntax: ATDD_global_parameter=value ATDD_device_parameter[index]=value Note: v Blank lines and lines starting with # are ignored. v No spaces may appear within each entry. v No trailing comments may appear on a variable definition line. Determine the Device Hardware Path for IBM Tape Drives: To determine the device hardware path for IBM tape drives with a SCSI attachment, perform the following steps: 1. Run ioscan to determine the hardware path (i.e., the SCSI adapter) the tape drive is connected to. # ioscan -f -C ext_bus 2. Record the hardware path entry of the adapter: For example: 0/10/0/0 3. Determine the SCSI target address of the tape drive. HWPATH = adapterpath.drivetargetaddress.0 (tape drive) For a tape drive at SCSI target address 3, the device hardware path is: 0/10/0/0.3.0 To determine the device hardware path for IBM tape drives with the Fibre Channel attachment, perform the following steps: 1. Run ioscan to determine the hardware path (i.e., the Fibre Channel) the tape drive is connected to. # ioscan -f -C tape 2. Record the hardware path entry of the Fibre Channel: For example: HWPATH = 0/5/0/0.8.0.255.7.9.0 Create the Hardware Path Entry: You must tell the driver which hardware path you want to attach to if you are not using the installation defaults for driver behavior. Create an entry in the /etc/rc.config.d/atdd configuration file for each device you want the driver to attach. For example: ATDD_HWPATH[0]=0/10/0/0.1.0 ATDD_HWPATH[1]=0/10/0/0.6.0 ATDD_HWPATH[2]=0/5/0/0.8.0.255.6.14.0 60 IBM Tape Device Drivers Installation and User's Guide
