320 Alphabetical list of commands
show volume-reservations
Description
Shows persistent reservations for all or specified volumes. The persistent group reservations (PGR)
mechanism enables application clients on multiple hosts to control access to a storage volume, and
limits access by other hosts.
Each host must be registered with the storage system in order to establish a persistent reservation for
a volume, thereby becoming a reservation holder.
If the system gets into an abnormal state and you need to remove all registrations and reservations
for specified volumes to return them to a “clean” state, you can use the
release volume
command.
This command must be used with care, as described in its help.
For more information about persistent reservations, see the SPC-3 specification at
http://www.t10.org
.
