First of all EMC ControlCenter is now part of the EMC Ionix Family and its now called Ionix ControlCenter.  No, we can not monitor Mirrorview Sessions for CLARiiON on ECC.  PFA EMC Ionix Contol Center Support Matrix which mentions list of CLARiiON Array can be discovered. (Page Number 113) and software you need to discover the same. (Page Number 115). I was unable to find any more relevant information for M/V in EMC ICC or ECC.  JFYI, if you are using Storage Provisioning Service, you can not delete the devices used by MirrorView. (Refer Page Number 152).
Does anyone know if this is possible? I'm not finding anything in the documents. If anyone knows about it I would appreciate it.
