— Background Initialization (BGI) Rate. Enter a number from 0 to 100 to
control the rate at which virtual disks are initialized in the background.
Background initialization makes the virtual disk immediately available for
use, even while the initialization is occurring. The higher the number, the
faster the initialization occurs. However, if a higher number is selected, the
system I/O rate may be slower.
— Check Cons
istency Rate. Enter a number from 0 to 100 to control the rate at
which a consistency check is done. A consistency check scans the consistency
data on a fault tolerant virtual disk to determine if the data is corrupted. The
higher the number, the faster the consistency check is done. However, if a
higher number is selected, the system I/O rate may be slower.
— Reconstruction Rate.
Enter a number from 0 to 100 to control the rate at which
reconstruction of a virtual disk occurs. The higher the number, the faster the
reconstruction will occur. However, if a higher number is selected, the system
I/O rate may be slower.

Note: Th

conditions on the controller. If the alarm is malfunctioning, you may need to silence it.

®
RAID Web Console 2 to increase the capacity of an existing virtual
disk by adding physical disk drives to it. In order to do this, you must be logged on to the
system in All Access mode.
Warning: B

To increase the capacity of a virtual disk, follow these steps:
1. User Logical View and select a Drive Group icon in
the left panel and then select
Go To -> Drive Group -> Modify Drive Group.
