Blink Drive LED
This command instructs the user-selected drive to blink its LED. The drive will continue to blink
its LED until either:
User presses Esc before the Administrator Utility times out
User issues the Blink Drive LED command again, which will toggle the command
OFF.
Clear MetaData
WARNING:
DO NOT use during normal operation!
All of the member drives in an array contain metadata in the first sectors of the drive. The
metadata is used by the RAID core so that on power-up (or after swapping of controllers),
each drive can be reassigned into its parent array.
This command clears the metadata off of the selected drive and allows the user to reuse a
drive in a new array that was previously a member of another array.
Down Drive
WARNING:
DO NOT use during normal operation!
This command is used for testing arrays and should not be used in normal operations. The
command sets the status of a drive in an array to "down". This forces the RAID code to remove
it from an array and marks the array as "critical".
Start Unit
WARNING:
DO NOT use during normal operation!
This command is used by engineering when testing various array configurations and should
not be used in normal operation.
