To diagnose suspected problems in XRC, you can direct a storage control to dump its internal control queues. This is called a state save. You can request a standard state save, which is followed by a warmstart, or a non-disruptive state save, which does not result in a warmstart. You can also supply additional descriptive information that is stored in the dump.
One statesave is allowed every 5 minutes. However, only 10 non-disruptive statesaves are allowed in a 24-hour period.
