Chapter 2: Using the Command Line Utility ● 25external# is the maximum number of external drives (such as the drives in a JBOD) that thecontroller may spin up at one time, from 0-20.LogicalDrive# is the logical drive number.Slowdown st# sets the disk drive slow-down timer, in minutes. Valid values are 0 (never), 3, 5,10, 20, 30, 60, 120, 180.Poweroff pt# sets the disk drive power-off timer, in minutes. Valid values are 0 (never), 3, 5,10, 20, 30, 60, 120, 180.Verify vt# sets the period of inactivity, in hours, after which an inactive drive (a drive that’salready powered down) is restarted to verify its operating condition. Once the check iscompleted, the drive is powered down and returns to its inactive state. Valid values are 0(never), 1, 2, 3, 8, 12, 24.Note: For the Slowdown, Poweroff, and Verify timers, st# must be less than pt#, and pt# mustbe less than vt#. You can set one or more timers, in any order, in a single command. Keep inmind that the Verify timer, vt#, is specified in hours; the other two timers are specified inminutes.ExamplesARCCONF SETPOWER 1 STAYAWAKE DISABLEARCCONF SETPOWER 1 SPINUP 4 4ARCCONF SETPOWER 1 LD 2 POWEROFF 60ARCCONF SETPOWER 1 LD 2 SLOWDOWN 20 POWEROFF 60 VERIFY 12arcconf setpriorityChanges a task’s execution priority or a controller’s global background task priority.SyntaxARCCONF SETPRIORITY [TASK ID] [current]ParametersController# is the controller number.Task ID is the number of the task to be changed. Use arcconf getstatus to obtain the task ID.Omit this parameter to set the controller’s global background task priority; that is, theexecution priority for all tasks on the controller.New Priority is: LOW, MEDIUM, or HIGH.Current (keyword) applies a global task priority change to running tasks. By default, a globalpriority change does not apply to running tasks.ExamplesARCCONF SETPRIORITY 1 <task_id> HIGHARCCONF SETPRIORITY 1 LOW CURRENT
