About online Dynamic Reconfiguration

System administrators and storage administrators may need to modify the set of LUNs provisioned to a server. You can change the LUN configuration dynamically, without performing a reconfiguration reboot on the host.


You can change the LUN configuration dynamically either using the Dynamic Reconfiguration (DR) tool or manually. Veritas recommends using the Dynamic Reconfiguration tool.
