Volume replication to multiple EqualLogic boxes

Dear All,

I have 3 equallogic storage boxes which has 36 TB capacity of each one.  I have scheduled ex2k7 volume replication for Storage1 to Storage2. The volume replication is happening daily.  But I want one more replica in Storage3.  So, I have modified the volume replication settings to storage3.  The new replication schedule is happening but the old replication scheduled has disabled.

Can i configure volume replication at a time to two different storage boxes?  If yes...   please tell me.

Thanks & Regards
