The physical disk is changed to the Ready state. The status of the physical disk is displayed under the
heading State.
NOTE: Try to use physical disks of the same capacity in a specific virtual disk. If you use physical
disks with different capacities in a virtual disk, all physical disks in the virtual disk are treated as if
they have the capacity of the smallest physical disk.
NOTE: To remove additional global or dedicated hot spares, follow step 1 to step 4.

Replacing An Online Physical Disk

In addition to the automatic Replace Member operation, you can manually replace any physical disk that

Stopping Background Initialization

Background initialization (BGI) is the automated operation in which parity is created and written. BGI does
not run on RAID 0 virtual disks. Under certain conditions, the BIOS Configuration Utility (<Ctrl> <R>)
displays a message if you want to stop a BGI in progress. An alert message is displayed if a BGI is in
progress and you start any of the following actions:
• A Full Initialization on the virtual disk
• A Fast Initialization on the virtual disk
