Each line of text in an ACU script file is written in the format option=value and can be in either uppercase or lowercase letters. You can improve the clarity of the script by leaving lines blank and by creating comments. To create a comment, enter a semicolon and then the comment text. ACU ignores all text on the same line after a semicolon. Operating modes Scripting in ACU has two modes of operation: · In Capture mode, the configuration of all internal and external array controllers that are connected to a server is saved to a script file. You can then use the script file to replicate the array configuration on other servers that have similar storage resources. NOTE: You can also perform array replication by using the HP Array Configuration Replicator (ACR). However, the two utilities are not functionally identical. ACU can read unmodified capture files from ACR, but ACR cannot necessarily use ACU files. · In Input mode, the array configuration that is specified in a script file is applied to a target system. The script file can be an unmodified or modified capture file, or you can write the script file from scratch. In Automatic mode, you can enter the values for a few critical options and allow ACU to use default values for all other options. In Custom mode, you can specify every detail of the array configuration. Input mode is subdivided into Automatic and Custom configuration modes. · · Command line syntax In Capture mode: cpqacuxe -c FILENAME Scripting in ACU 31 If you do not specify a capture file name, ACU gives the file the default name of ACUCAPT. INI and places it in the ACU working directory. In Input mode: cpqacuxe -i FILENAME If you do not specify an input file name, ACU gives the file the default name ACUINPUT. INI and places it in the ACU working directory. If any errors occur during either process, these errors are noted in the file ERROR. INI that is logged to the default working directory. Sample custom input script The following script gives all possible values for each option. · · · If an option is shown in bold type, you must enter a value for that option. If a value is shown in bold type, ACU uses that value as a default setting when creating new logical drives. An asterisk next to a line denotes that the line is not used in Automatic mode. You can use this script as a template for your own script.

Each category has several scripting options, but you do not always need to assign values to every option. ACU can use default values in some cases, while in other cases, a given option might not be relevant for a particular controller or operating mode. [. . . ] This configuration is useful when cost, performance, and data availability are equally important. Advantages: · · · Has high read performance. Data is not lost if one physical drive fails. More drive capacity is usable than with RAID 1+0--parity information requires only the storage space equivalent to one physical drive. [. . . ]
