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 8):
The method of  claim 7 , wherein the destination storage array further includes a migration controller component; and\n wherein sending the hold I/O message to all host computers in the cluster comprises the migration controller component in the destination storage array sending the hold I/O messages to all host computers in the cluster.
