What Can I Do If a Local Storage System Cannot Discover the Remote LUN Corresponding to an External LUN When the Physical Connection Between a Heterogeneous Storage System and the Local Storage System Is Changed?

What Can I Do If a Local Storage System Cannot Discover the Remote LUN Corresponding to an External LUN When the Physical Connection Between a Heterogeneous Storage System and the Local Storage System Is Changed?

Question

What can I do if a local storage system cannot discover the remote LUN corresponding to an external LUN when the physical connection between a heterogeneous storage system and the local storage system is changed?

Answer

For some heterogeneous storage systems, their initiators and targets are in a one-to-one mapping relationship. After the physical connection is changed, the mapping relationship is also changed. You must re-establish a mapping relationship among initiators, targets, and LUNs on the management interface of the heterogeneous storage system. (If the local storage system fails to automatically discover LUNs, manually scan for LUNs.) Otherwise, the heterogeneous storage system will not report LUNs.
