Abstract
Techniques introduced here swap logical unit meta-data of a logical unit without offlining the logical unit. In accordance with the techniques, a connection between a network storage controller and a host for the logical unit is maintained while meta-data of the logical unit are swapped with another logical unit available to the network storage controller. The swapping substitutes one logical unit for another without disconnecting the host. Advantageously, the host is not required to perform operations to re-establish a connection. Various software and hardware units can implement the techniques described herein.
