Appendix C: Using the Adaptec RAID Configuration Utility ● 99Power Management SettingsNote: When power management is disabled, no related options will be displayed.Note: Make sure the operating system driver supports power management.Note: Default settings are shown in bold type.PHY SettingsNote: For 3-series controllers, these settings are read-only and non-editable. These settingsare not available on the Adaptec RAID 31205 and Adaptec RAID 31605 controllers.Formatting and Verifying Disk DrivesYou can use the disk utilities to low-level format or verify your disk drives. (New disk drives arelow-level formatted at the factory and do not need to be low-level formatted again.)Caution: Before you format a disk drive, back up all data. Formatting destroys all data ona disk drive.Option DescriptionPower ManagementSettingsWhen enabled, switches the system to low power state, based on thespecified settings.Time Zone The time zone of the place in which the system is located. Time specificpower management settings are implemented based on the set timezone. By default, it is set to 00:00.The valid range for the time zone settings is -12:00 to +12:00.Stay Awake Start The time from which the system should operate in the full power mode,irrespective of other power management settings, daily. By default it isset to 00:00.The valid range is 00:00 to 23:59.Stay Awake End The time until which the system should operate in the full power mode,irrespective of other power management settings, daily. By default it isset to 00:00.The valid range is 00:00 to 23:59.Spin Up Limit (Internal) The number of internal drives to be spun up at any given moment. Bydefault it is set to 0. In the default setting, all the internal drives willspin up.Spin Up Limit (External) The number of external drives to be spun up at any given moment. Bydefault it is set to 0. In the default setting, all the external drives willspin up.Option DescriptionPHY Rate The data transfer rate between the controller and devices. The default setting isAuto, which allows the SAS card to adjust the data transfer rate, as needed. Forlow-port 5-series RAID controllers (5085, 5405), you can set the PHY rate to1.5Gb/second or 3.0Gb/second (the maximum rate).CRC Checking When enabled, determines whether the controller verifies the accuracy of datatransfer on the serial bus. Default setting is Yes (enabled). Set to No (disabled)only if the controller is connected to a device that does not support CRC Checking.SAS Address In a situation where you want each phy on a controller to be in a different SASdomain, this setting specifies a unique world-wide name for each phy. Defaultis 0.Note: This setting is for SAS address conflict resolution only and should otherwiseremain at its default value.!
