How to delete non-existant system from the Cluster "-i"

Hell Expert,

I am facing one simple but bit tricky issue in VCS.

one non-existant system added in the cluster which has hostname "-i" . i am not aware how this system added in the list. find bellow system list.

bash-3.00# hasys -list
-i
MMINDIA01
MMINDIA02
MMINDIA03
MMINDIA04

i tried with "hasys -delete -i", "hasys -delete "/i" but no success.

Kindly help on priority.
