Abstract
Provided are a method, system, and article of manufacture, wherein a request is received for switching a logical volume from one state to another state, wherein the logical volume is in a mirrored state if data corresponding to the logical volume is mirrored from a first storage to a second storage, and wherein the logical volume is in a non-mirrored state if the data corresponding to the logical volume is not mirrored from the first storage to the second storage. A determination is made as to whether to perform the switching, in response to receiving the request.
Claims34
A method, comprising:
- receiving a request for switching a logical volume from one state to another state, wherein the logical volume is in a mirrored state if data corresponding to the logical volume is mirrored from a first storage to a second storage, and wherein the logical volume is in a non-mirrored state if the data corresponding to the logical volume is not mirrored from the first storage to the second storage;
- and
- determining whether to perform the switching, in response to receiving the request.
A system, comprising:
- memory;
- first storage coupled to the memory;
- second storage coupled to the memory;
- and
- processor coupled to the memory, wherein the processor is capable of performing operations, the operations comprising:
- (i) receiving a request for switching a logical volume from one state to another state, wherein the logical volume is in a mirrored state if data corresponding to the logical volume is mirrored from the first storage to the second storage, and wherein the logical volume is in a non-mirrored state if the data corresponding to the logical volume is not mirrored from the first storage to the second storage;
- and
- (ii) determining whether to perform the switching, in response to receiving the request.
An article of manufacture, wherein the article of manufacture is capable of causing operations in a machine coupled to a first storage and a second storage, the operations comprising:
- receiving a request for switching a logical volume from one state to another state, wherein the logical volume is in a mirrored state if data corresponding to the logical volume is mirrored from the first storage to the second storage, and wherein the logical volume is in a non-mirrored state if the data corresponding to the logical volume is not mirrored from the first storage to the second storage;
- and
- determining whether to perform the switching, in response to receiving the request.
A method for deploying computing infrastructure, comprising integrating computer-readable code into a computing system, wherein the code in combination with the computing system is capable of performing:
- receiving a request for switching a logical volume from one state to another state, wherein the logical volume is in a mirrored state if data corresponding to the logical volume is mirrored from a first storage to a second storage, and wherein the logical volume is in a non-mirrored state if the data corresponding to the logical volume is not mirrored from the first storage to the second storage;
- and
- determining whether to perform the switching, in response to receiving the request.
