situations where a controller stall is preventing I/O operations from completing,
and recovers the system so that at least one controller is operational, thus
avoiding data-unavailability situations.

restart-on-capi-fail string Shows whether a Storage Controller that experiences a CAPI hang will be forced

capability to create a virtual pool larger than 512 TiB on each controller by limiting
the number of user-defined snapshots that can be created in snapshot trees.
● enabled or on: The maximum size for a virtual pool will increase to 1024
TiB (1 PiB). The maximum number of volumes per snapshot tree will decrease
to 9 (base volume plus 8 snapshots).
● disabled or off: The maximum size for a virtual pool will increase to 512
TiB. The maximum number of volumes per snapshot tree will decrease to 255
(base volume plus 254 snapshots).
