Performing A Clear Physical Disk And Cancel Clear
Does my controller support this feature? See Supported Features.
Select the Clear Physical Disk task to erase data residing on a physical disk. The Clear task applies to
physical disks that are in Ready state and that contain data or that are in Clear state.
NOTE: A physical disk may display the Clear state if it is a member of a virtual disk that is being slow
initialized. Performing a Cancel Clear task on the physical disk causes the Slow Initialize task to be
canceled for the entire virtual disk.
To clear the physical disk:
1. Review the physical disk to be erased. Ensure that it does not contain necessary data and make a
backup if necessary. If you want to blink the physical disk, click Blink button.
2. Click Clear when you are ready to erase all information on the physical disk. To exit without clearing
the physical disk, click Return to Previous Page.

Enabling Revertible Hot Spare
Does my controller support this feature? See Supported Features.
Select the Revertible Hot Spare task to copy data back from a hot spare to a physical disk.
If the physical disk in a virtual disk fails, the data on the failed disk is copied to the assigned hot spare. If
you replace the failed disk with a new physical disk and if you have enabled the Revertible Hot Spare
task, the data is copied from the hot spare to the new disk.
You can also use the Revertible Hot Spare task to copy data from a physical disk to the hot spare on a
predictive failure event.
If Revertible Hot Spare is enabled and the physical disk is SMART-enabled, the controller firmware
automatically starts copying data from the SMART-enabled disk in the virtual disk to the hot spare.
NOTE: To use the Revertible Hot Spare task, ensure that you have assigned a hot spare to the
virtual disk.
