Abstract
In one embodiment, a computer-implemented method includes making a determination, by a computer, to perform a transforming operation on a shared volume. A notify command is sent to a storage controller of the shared volume, the notify command including an action to be taken by other hosts connected to the shared volume. A message is received from the storage controller, the message indicating that responses have been received from the other host systems connected to the shared volume. A determination is made as to whether to perform the transforming operation based on the responses. The transforming operation is performed on the shared volume in response to the responses from the other host systems indicating that the other host systems successfully performed the action specified in the notify command.
