Misc Configuration As an Advanced user, you can view the following categories of configuration settings: general, RAID controller, EMP, security access to services, user preferences, and Network Time Protocol (NTP). To view miscellaneous configuration settings: ● Select Monitor > Status > Advanced Settings > Misc Configuration. The information is displayed in five panels. The General Configuration Status panel shows the following information: ■ Background Scrub - Shows whether virtual disks are automatically analyzed to find disk-drive defects. The default is Enabled. If Enabled, disk drives associated with virtual disks are continuously analyzed and information about disk-drive defects is reported and is stored in disk-drive metadata. If Disabled, virtual disks are not automatically scrubbed. For more information, see "Enabling and Disabling Background Scrub for Disks" on page 189. ■ Partner Firmware Upgrade - Shows whether the system automatically upgrades firmware on one controller when a newer version of firmware is loaded on the partner controller. The default is Enabled. If Enabled, the partner controller is automatically upgraded. If Disabled, the partner controller must be upgraded manually. If directed by a service technician, a Manage user can disable partner firmware upgrade on the Manage > General Config > System Configuration page. ■ Utility Priority - Shows the priority at which all system utilities run when there are active I/O operations competing for the controller's CPU. The setting can be High (default), Medium, or Low. The default is High. For more information, see "Changing Utility Priority" on page 183. ■ Host Control Of Cache - Shows whether hosts are prevented from using SCSI MODE SELECT commands to change the system's write-back cache setting. Some operating systems disable write cache. The default is Disabled. If host control is Disabled, the host cannot modify the cache setting. For more information, see "Controlling Host Access to the System's Write-Back Cache Setting" on page 190. ■ Dynamic Spare - Shows whether the system can automatically take a properly sized available drive to reconstruct a virtual disk when no spares are designated. The default is Disabled. For more information, see "Managing Dynamic Spares" on page 80. Chapter 5 Monitoring System Status 165
