Abstract
A computer-implemented method, according to one approach, includes: sending a notification to a host regarding a first logical unit number (LUN) in response to receiving an indication that a first node will be taken offline. The first LUN that the notification is sent to has a preferred communication path that extends through the first node. Communication paths extending through the first node are blocked and communication paths extending through a second node are promoted. Moreover, in response to determining that existing I/O operations previously assigned to the first node have been completed, the first node is taken offline. I/O operations are thereby sent to the first LUN through the second node while the first node is offline.
