SET NVS
Messages
Response 2:
Immediate Response: If you enter the SET NVS OFF command and the NVS is
made unavailable to the subsystem immediately, the following response is
displayed. This response is repeated for each unique subsystem identified by the
devices specified on the command
rdev Nonvolatile storage has been deactivated.
rdev
is the real device number of one of the specified devices in a subsystem for
which the NVS has been deactivated.
Delayed Response: If the NVS is not made unavailable to the subsystem
immediately, the following response is displayed:
Command started: SET NVS OFF rdev.
When the NVS is made unavailable to the subsystem, the following responses are
displayed:
rdev Nonvolatile storage has been deactivated.
Under certain circumstances, it is possible that a cache storage subsystem does
not notify CP when it has made the NVS unavailable to the subsystem. When this
occurs, the appropriate command response cannot be generated. Under these
circumstances, command processing is ended after generating the following
response:
Command results lost: SET NVS OFF rdev.
In this case, the QUERY NVS command can be issued to determine the state of the
nonvolatile storage.
If errors occur during the asynchronous processing of the command that prevent
the successful completion of the command, the following response is displayed:
Command failed: SET NVS OFF rdev.
rdev
is the real device number of one of the specified devices in a subsystem for
which the command has failed.
Response to System Operator: If the originator of the command is not the system
operator, the following response is issued to the system operator when the NVS
has been made unavailable to the subsystem. This response is also repeated for
each unique subsystem identified by the devices specified on the command line.
rdev Nonvolatile storage was deactivated by userid.
rdev
is the real device number of one of the specified devices in a subsystem for
which the NVS has been deactivated.
userid
is the ID of the user who issued the command.
