Option Description
Rebuild Use this option to rebuild a failed physical drive that is part of a redundant
array. Data from a good drive or drives rebuilds the failed drive.
Clear Use this option to clear the data from SCSI disk drives. This is for SCSI
drives only.
Force Online Use this option to change the state of the selected disk drive to Online.
Force Offline/
Remove HSP Use this option to change the state of the selected disk drive to Fail.
Make Hot Spare Use this option to designate the selected disk drive as a hot spare. A hot
spare is an idle, powered-on standby drive ready for use if another drive fails.
When a drive fails, the controller firmware automatically rebuilds the data on
the hot spare from a redundant drive or drives. Data can be rebuilt only from
logical drives with redundancy (RAID 1, 5, 10, and 50, not RAID 0). The hot
spare must be at least as large as the failed drive it is replacing.
View Drive Information Use this option to display the drive properties for the selected physical
device, such as device type, capacity, vendor ID, and device errors.
View Rebuild Progress Use this option to enable synchronous negotiation with a physical device.
This is available only for SCSI controllers.
View Rebuild Progress Use this option to view the progress of the physical drive rebuild.

2, 3, 4, or Enhanced. The default setting is Enhanced. This option is
available for SCSI controllers only.
Transfer Speed Option Use this option to set the data transfer speed.
