Set Commandswww.3ware.com 111Set CommandsThese commands allow you to set certain controller and unit specificparameters as described below. The set command can be used to set its rebuildrate, and enable or disable cache. For information about viewing informationabout the controller and units, see the “Info Commands” on page 85.Syntaxset rebuild c <1..5>set cache c u on|offset verify c <1..5> (Note: 9000 only)set autoverify c u on|off (Note: 9000 only)set overwriteECC c u on|off (Note: 9000 only)Parameters rebuild - sets the rebuild rate (per controller basis) and also sets theinitialize rate. cache - enables or disables caching on a per array or unit basis for RAID1, 5, and 10 arrays. verify - sets the verify rate (per controller basis) autoverify - enables or disables the automatic verification (per unit basis) overwriteECC - enables or disables the ignoreECC function dring rebuild(per unit basis)Note: A value of 1 indicates slowest I/O and fastest rebuild rate. Avalue of 5 indicates fastest I/O and slowest rebuild. Interim valuesscale linearly (e.g., a value of 3 indicates a rebuild rate half as fastas a rebuild of 1).set rebuildcid 1..5This command allows you to set the priority of rebuild in relation to I/Ooperations. Setting this value to 1 implies that rebuilds should consume moreresources (cpu time, I/O bandwidth) to complete its task. Conversely, settingthis value to 5 implies that I/O has higher priority and rebuild. This commandapplies to 7000, 8000, and 9000 models. For the 7/8000 series, the rebuild ratealso applies to the verify and background scrub tasks.set verifycid 1..5This command allows you to set the priority of verification in relation to I/Ooperations. Setting this value to 1 implies fastest verify, and 5 implies fastestI/O. Note that This feature only applies to 9000 series controllers.
