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.

Abstract
A method can include identifying a storage area in the storage system for access control, assigning a switching criterion to modify allowable access to the identified storage area, where the identified storage area supports pre-staging of provisioned data, and blocking a select access attempt to the identified storage area as a function of the switching criterion.

7. An apparatus for protecting pre-staged provisioned data in a storage system, the apparatus comprising:
-
an access switch, the access switch controlling access to an identified storage area having contents, in the storage system, wherein the identified storage area supports pre-staging of provisioned data, the access switch performing a method comprising; receiving a switching criterion to modify allowable access to the identified storage area; 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. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer program product for protecting pre-staged provisioned data in a storage system, the computer program product comprising:
-
a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for implementing a method comprising; receiving a switching criterion to modify allowable access to an identified storage area, having content, 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. - View Dependent Claims (14, 15, 16, 17, 18)
