Clear Nexus Settings
The Clear Nexus Settings action is used to clear legacy and persistent reservations placed on a
changer device. This can be used to recover from the loss of a host that has placed a reservation
on the changer. If an application is reporting “Reservation Conflict” errors when it attempts to
access the changer device or “Medium Removal Prevented” errors occur when attempted to remove
tapes from the changer even after the application is no longer using the library, this function can
clear those settings.
