Abstract
A computer-implemented method includes receiving, utilizing a processor, a fencing command at a storage controller from an initiating host system. The fencing command identifies a shared volume. Additionally, the computer-implemented method includes determining which other host systems are connected to the shared volume, and fencing each of the other host systems connected to the shared volume by setting a fencing indicator for each of the other host systems. Still yet, the computer-implemented method includes sending a notification to each of the other host systems that have been fenced, and receiving an unfencing command from at least one of the other host systems that have been fenced.
