Appendix D: Using the Array Configuration Utility for DOS ● 95Running the ACU Using ScriptsTo work in the ACU using scripts:1 Insert the ACU floppy disk (see page 94), then start or restart your computer.The computer boots to the DOS command line.2 Type ACU on the command line, specify a script file, and specify either the /P or /R switcheslisted in the following table. (Don’t specify both.)You may also add one or both of the optional switches.Note: Command line syntax is not case sensitive.About Playback ModeIn this mode, the ACU reads the contents of the specified script file and creates arrays based onthe keywords specified in the script.The syntax is ACU /P <file> where file is the name of the script file. The file parameter caninclude a drive, directory, filename, and extension. If no drive or directory is specified, thescript file used should be placed in the same location as the ACU executable.Note: The script file syntax allows only one hot spare to be assigned to an array. Therefore,when recording a RAID 10, the ACU can’t map hot spares assigned to the individual mirror setsin the resulting script file. Instead, the ACU creates a single list for all hot spares assigned tothe RAID 10. For more information, see Method Keyword on page 99 .Switch Description/P <file> Playback Mode—The ACU reads the contents of the specified script file andcreates arrays and configures channel settings based on the keywordsdefined in the script. See page 95./R <file> Record Mode—The ACU writes a RAID controller’s existing array configurationto a specified script file, which lets you create the same configuration byrunning the ACU in playback mode (/P switch) with the resulting script. Seepage 96./L <file> (Optional) Log Filename Switch—If you include this switch, the ACU recordsits activity and any errors it encounters in the log file. If you do not include thisswitch, the ACU displays activity and errors on the screen.The file is a standard MS-DOS file, which can include a drive, directory,filename, and extension. Only the filename and extension (.log) are required. Ifno drive or directory is specified, the file is placed in the same location as theACU executable./C <number> (Optional) Controller Number Switch—In systems with more than onecontroller, this switch specifies which controller to change, where number isthe controller number. The default controller number is 0.Note—The number assigned to a particular controller depends on thecontroller’s physical PCI slot and the order in which your system scans its PCIslots.
