Abstract
A method for limiting I/O access in shared storage systems is disclosed. In one embodiment, such a method includes establishing, for a volume, a list of address spaces that are authorized to access the volume. The method further receives an I/O request to access the volume and determines whether the I/O request originates from one of the address spaces identified in the list. If the I/O request originates from one of the address spaces in the list, the method passes the I/O request to the volume. If, on the other hand, the I/O request does not originate from one of the address spaces in the list, the method blocks the I/O request. A corresponding system and computer program product are also disclosed.
