Abstract
For a first server virtual machine (VM) virtualizing a logical volume in a read/write mode for a client VM, a second server VM virtualizing the logical volume in an off mode is instantiated. The logical volume comprises a virtualization of a portion of physical storage. At the first server VM, the logical volume is deactivated, the deactivating disallowing the first server VM from performing a storage request from the client VM. At the second server VM, the logical volume is activated, the activating performed by causing the second VM to virtualize the logical volume in the read/write mode, the activating allowing the second server VM to perform the storage request.
