HI Dennis, Well let me tell you the concept here first, This session of which you are thinking as will run short of the Luns in RLP, If the LUns become full while the session is running the next avaialable reserved LUn will be assigned automatically to the source Lun. If there are no more luns available in the RLP then the session that caiused the RL to become full will be terminated automatically....without having any impact on the other session which is also running simultaneusly. Then any reserved Luns used by the first session will return to the RLP being as available for use for some other sessions. Also when RLP's come close to 50% it triggeres a alert through event Monitor. For detailed studies you can refer the RLP config guide at powerlink.
Dear All,  I have two LUNs to config snapshot and allocated two reserve luns into pool.  what will happen if one reserve lun is full?  Will all snapshot fail due to no spaces in reserve lun poor? or only one snapshot fail due to his reserve lun was full?  Thank you for any input. Dennis Dai 
what will happen reserve lun poor is full?
