26 About PERC 6 and CERC 6/i ControllersFull Initialization of Virtual DisksPerforming a Full Initialization on a virtual disk overwrites all blocks anddestroys any data that previously existed on the virtual disk. Full Initializationof a virtual disk eliminates the need for that virtual disk to undergo aBackground Initialization and can be performed directly after the creation ofa virtual disk.During Full Initialization, the host is not able to access the virtual disk.You can start a Full Initialization on a virtual disk by using the Slow Initializeoption in the Dell OpenManage storage management application. To use theBIOS Configuration Utility to perform a Full Initialization, see "InitializingVirtual Disks" on page 88.NOTE: If the system reboots during a Full Initialization, the operation aborts and aBGI begins on the virtual disk.Fast Initialization of Virtual DisksA fast initialization on a virtual disk overwrites the first and last 8 MB of thevirtual disk, clearing any boot records or partition information. This operationtakes only 2–3 seconds to complete and is recommended when recreatingvirtual disks. To perform a fast initialization using the BIOS ConfigurationUtility, see "Initializing Virtual Disks" on page 88.Consistency ChecksCC is a background operation that verifies and corrects the mirror or paritydata for fault tolerant virtual disks. It is recommended that you periodicallyrun a consistency check on virtual disks.You can manually start a consistency check using the BIOS ConfigurationUtility or a OpenManage storage management application. To start a CCusing the BIOS Configuration Utility, see "Checking Data Consistency" onpage 88. CCs can be scheduled to run on virtual disks using a OpenManagestorage management application.By default, CC automatically corrects mirror or parity inconsistencies.However, you can enable the Abort Consistency Check on Error feature onthe controller using Dell OpenManage storage management application.With the Abort Consistency Check on Error setting enabled, consistencycheck notifies if any inconsistency is found and aborts instead ofautomatically correcting the error.
