Clear Physical Disk and Cancel Clear
Does my controller support this feature? See "Supported Features."
Use 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.
To clear the physical disk:
1. Review the physical disk that will be erased by the clear task. Be sure that it does not contain necessary data and make a backup if necessary. If you
want to blink the physical disk, click the 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 Go Back to Previous Page.
To locate this task in Storage Management:
1. Expand the Storage tree object to display the controller objects.
2. Expand a controller object.
3. Expand a Connector object.
4. Expand the enclosure or Backplane object.
5. Select the Physical Disks object.
6. Select Clear from the Available Tasks drop-down menu of the physical disk you want to clear.
7. Click Execute.
Revertible Hot Spare
Does my controller support this feature? See "Supported Features."
Use 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 erstwhile 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.
To enable Revertible Hot Spare:
1. On the Change Controller Properties page, enable Revertible Hot Spare and Auto replace on predictive failure.
2. Click Apply Changes.
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 cancelled for the entire virtual disk. See "Format and Initialize; Slow and Fast Initialize" and
"Considerations for Slow Initialize" for more information.
NOTE: To use the Revertible Hot Spare task, you should have assigned a hot spare to the virtual disk.
NOTE: If the disk is not SMART-enabled or if the Auto Replace on Predictive Failure option is disabled, the failed disk will not be replaced automatically.
