1. A method for protecting pre-staged provisioned data in a storage system, the method comprising:

  • identifying a storage area, having contents, in the storage system for access control;

    assigning a switching criterion to modify allowable access to the identified storage area, wherein the identified storage area supports pre-staging of provisioned data;

    blocking a select access attempt to the identified storage area as a function of the switching criterion, wherein the select access attempt is from a host image executing on a logical partition (LPAR) of a host server, wherein the contents in the identified storage area is modified, while the select access attempt is blocked; and

    blocking an additional access attempt from a second host image executing on a second LPAR, wherein the additional access attempt is blocked without respect to the switching criterion,wherein all accesses to the first and second host images are blocked.
