The following might help. PSE can try to remove the hot spare and then recover the drive that dropped (Spin it up). Hopefully the drive will stay up long enough for you to move ahead and make any changes you need from the host.
 Hi     I am facing issues to delete devices from DMX array.When running the symconfigure commands,I am getting the error in prepare step looged in symapi log " some configuration Changes can't be done if a SPARE is invoked".I chceked in the array that two drives  was failed and hotspare invok was done .This array is going to retire and we do not want to replace teh disks other than deleting the devices.Please let me know how to complete the delete device task  without repacing the disks.  Thanks  Swarup
