HP-UX Device Driver (ATDD) 2. Check the README file and verify that your system is configured appropriately for installing ATDD. 3. Ensure that the tape drives to be managed by ATDD are powered on. 4. Install and configure the software. Note the following facts about the command sequences described in this section: v In some of the examples, filenames given on the command-line must be referenced with an absolute path. Using 'pwd'/filename to reference a file instead of filename ensures this. v All the software distributor commands (for example, swinstall or swcopy) can first be run with the -p flag to preview the command. After observing the preview output, you can reissue the command without the -p flag to perform the actual operation. v The software distributor commands are moderately complex scripts that frequently require several steps. The steps are typically Selection, Analysis, and Execution. Each step may produce useful information and error messages. It is a good idea to observe carefully the results of the installation process as it occurs. If you encounter unexpected results during the installation, check the associated log file. While using the software distributor commands, you may encounter the following error about mounted file systems: ERROR: "hostname/": One or more filesystems that appear in the filesystem table are not mounted and cannot be mounted. Many commands (for example, swinstall and swremove) attempt to mount all file systems in the /etc/fstab file at the start of the analysis phase. This ensures that all listed file systems are mounted before proceeding. This also helps ensure that files are not loaded into a directory that may be below a future mount point, but it often causes an error with NFS mounted file systems. This error can be overridden using '-x' to set the mount_all_filesystems option to FALSE. When this option is used, the command finishes with a warning indicating that no attempt is made to mount all file systems. For example # swinstall -x mount_all_filesystems=false -x autoreboot=true atdd WARNING: "hostname:/": There will be no attempt to mount filesystems that appear in the filesystem table. Create the Configuration File A configuration file must be created that tells the device driver how to customize your configuration. The file is named etc/rc.config.d/atdd.cfg and has the following syntax: ATDD_global_parameter=value ATDD_device_parameter[index]=value Note: v Blank lines and lines that start with # are ignored. v No spaces can appear within each entry. v No trailing comments can appear on a variable definition line.
