Abstract
A method and a storage system are provided for accessing volumes. The storage system provisions to a host, a place holder handle configured for allowing access to any volume selected by the host and allowed to be accessed by the host. The volume forms part of accessible volumes included in the storage system. The storage system receives from the host a first request for associating the place holder handle with a first selected volume from among the accessible volumes and enables the host to access the first selected volume in response to receiving an access request indicative of the place holder handle.
Claims22
A method for accessing volumes, comprising:
- (a) provisioning by a storage system to a host, a place holder handle configured for allowing access to any volume selected by the host and allowed to be accessed by the host, wherein said volume forms part of accessible volumes comprised in said storage system;
- (b) receiving from the host a first request for associating said place holder handle with a first selected volume from among said accessible volumes;
- (c) enabling the host to access said first selected volume in response to receiving an access request indicative of said place holder handle.
A storage system for accessing volumes, comprising:
- a storage controller configured to provision to a host, a place holder handle configured for allowing access to any volume selected by the host and allowed to be accessed by the host, wherein said volume forms part of accessible volumes comprised in said storage system;
- a data communication interface, coupled to the storage controller, for receiving from the host a first request for associating said place holder handle with a first selected volume from among said accessible volumes;
- the storage controller is further configured to enable the host to access said first selected volume in response to a reception of an access request indicative of said place holder handle.
A non-transitory computer readable medium that stores instructions for:
- (a) provisioning by a storage system to a host, a place holder handle configured for allowing access to any volume selected by the host and allowed to be accessed by the host, wherein said volume forms part of accessible volumes comprised in said storage system;
- (b) receiving from the host a first request for associating said place holder handle with a first selected volume from among said accessible volumes;
- (c) enabling the host to access said first selected volume in response to receiving an access request indicative of said place holder handle.
A method for accessing volumes, comprising:
- (a) provisioning by a storage system to a host, a place holder handle configured for allowing access to any volume selected by the host from a certain volume family that comprises an original volume and derived volumes;
- (b) receiving from the host a first request for associating the place holder handle with a first selected volume from the certain volume family;
- (c) enabling the host to access said first selected volume in response to receiving an access request indicative of said place holder handle.
