Abstract
A storage controller determines a presence of an indication from an Input/Output (I/O) enclosure that the I/O enclosure will perform a shutdown after a predetermined amount of time. The storage controller determines whether the I/O enclosure provides a last path to data stored in a storage device. A request is transmitted to the I/O enclosure to perform either an orderly shutdown or abort the shutdown, based on the whether the I/O enclosure provides the last path to the data stored in the storage device.
