NOTE: You cannot disable BGI permanently. If you cancel BGI, it automatically
restarts within five minutes. For information on stopping BGI, see "Stopping
Background Initialization" on page 84.
NOTE: Unlike full or fast initialization of virtual disks, background initialization does
not clear data from the physical disks.
NOTE: CC/BGI typically causes some loss in performance until the operation
completes.
Consistency Check (CC) and BGI perform similar functions in that they
both correct parity errors. However, CC reports data inconsistencies through
an event notification, but BGI does not. You can start CC manually, but not
BGI.
Full Initialization of Virtual Disks
Performing a full initialization on a virtual disk overwrites all blocks and
destroys any data that previously existed on the virtual disk. Full initialization
of a virtual disk eliminates the need for the virtual disk to undergo a BGI.
Full initialization can be performed after the creation of a 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 Initialize
option in the Dell OpenManage storage management application. For more
information on using the BIOS Configuration Utility to perform a full
initialization, see "Initializing Virtual Disks" on page 61.
NOTE: If the system reboots during a full initialization, the operation aborts and
a BGI begins on the virtual disk.
Fast Initialization of Virtual Disks
A fast initialization on a virtual disk overwrites the first and last 8 MB of the
virtual disk, clearing any boot records or partition information. The operation
takes only 2–3 seconds to complete and is recommended when you are
recreating virtual disks. To perform a fast initialization using the BIOS
Configuration Utility, see "Initializing Virtual Disks" on page 61.
