Abstract:
While migrating a source volume to a destination storage array, disabling the source volume causes a source storage array to send a non-standard failure status code to all host computers in a cluster that includes the source storage array and the destination storage array. While the source volume is disabled with regard to standard host I/O requests received from host computers in the cluster, in response to receipt of the non-standard failure status code, a customized plugin added to the host computers transfers persistent reservation information to the destination storage array using non-standard read and set persistent reservation information commands. The destination volume is then enabled to process host I/O requests in accordance with the transferred persistent reservation information, and an active path for accessing the source volume is modified in each one of the host computers in the cluster to indicate the destination volume in the destination storage array.

Claim (Index 15):
The non-transitory, computer-readable medium of  claim 14 , wherein the method of providing seamless migration of a source volume located in a source storage array to a destination storage array that is caused to be performed by the processing units when the instructions are executed by the processing units further comprises:\n Wherein transferring the persistent reservation information to the destination storage array by at least one of the host computers in the cluster comprises the customized plugin component added to the multi-pathing component in at least one of the host computers in the cluster transferring the persistent reservation information from the source storage array to the destination storage array.
