Claim 4:
5. The method of claim 3, wherein multiple host-associated virtual volumes (vVols) are migrated concurrently, and further including, to manage potential race conditions between AENs and log accesses, (1) when a first AEN is sent on a controller of the host computer, temporarily disabling the AEN sending for the host computer until the first AEN is resolved, (2) including in the log file respective identifications of any additional vVols that have become ready for cutover while the AEN sending is disabled, so that the host computer receives notification of the additional vVols when retrieving the log page in response to the first AEN, and (3) when the host computer retrieves the log page, then enabling the AEN sending for the host computer to enable additional AENs to be sent to the host computer for other vVols that subsequently become ready for cutover.
