Changing the Global Mirror session performance parameters

Once the Global Mirror session is started, you cannot issue an RSESSION START command to that session with different performance parameters specified for CGINTERVAL, CGDRAIN, or COORDINTERVAL. To change these parameters:

1. Issue the RSESSION PAUSE command to the same CKD LSS in the master storage control where the start was issued.
2. Issue the RSESSION RESUME command with the new performance parameters to any CKD device and LSS in the master storage control

If you issue RSESSION START with different performance parameters to a session that is either active or paused, the new parameters are ignored. If you issue RSESSION RESUME without specifying any performance parameters, the default values are applied and any custom values previously specified with START are lost. If you want to specify any performance parameter with RSESSION START or RSESSION RESUME, you must specify all three performance parameters.
