If message IOS071I occurs for a shared device, the operator should
check the operating condition of the sharing systems. If any system
is not operational, it could be the cause of the start-pending because
the system could still hold an allegiance that it had when it became
non-operational. Operator action depends on the condition of the
non-operational system:
If the system is in the check-stop state or in a non-restartable
wait state, the operator should immediately initiate an interface
reset to that device from the system console of the non-operational
system. If the interface reset fails to release the device, the operator
should issue a system reset from the system console of the non-operational
system.
These actions should be taken before trying to recover
the non-operational system, to allow the other operational systems
that are sharing I/O with the non-operational system to continue with
as little disruption as possible.
If the system is in the stopped state, the operator should try
to determine why it is stopped and, if appropriate, start it again.
If the system issued message IOS431I, take the actions described
in the operator response for that message.
