C-2Command Line Interface (CLI)CLI commands enable you to automate testing or array creation ina production environment using Windows command scripts andLinux and UNIX shell scripts.This appendix describes briefly some of the commands available inthe CLI. For a full description of all the CLI commands, refer to theCLI Software Reference Guide.TerminologyYour Serial ATA adapter has the following restrictions with regardto CLI terminology and nomenclature: Channel/LUN—Channel always equals 0; LUN always equals 0. ID—“ID” always means “port.”In other words, in the device ID format C:PT:L, where C representsChannel, PT represents Port, and L represents LUN, only the valuefor Port is used.The following terms are used in discussing the CLI: Array, container—A logical disk created from available space andmade up of one or more segments on one or more physical disks. Stripe, chunk—Contiguous set of data distributed across all thedisks in an array. A striped array distributes data evenly acrossall members in equal-sized sections called stripes. Free or available space—Space on an initialized disk that is notin use. Segment, partition—Contiguous area of a physical drive thatmakes up some or all of an array. Hot spare, failover disk—A hard drive, an array member, thatis not used in day-to-day data storage but is instead reserved foruse as a replacement for one of the other drives in the array inthe event of a failure.Additional RAID terms are defined in the Glossary.Accessing the CLIThe method you use to access the CLI depends on the operatingsystem, as described below.
