Solution if the host fails to detect LUNs

Solution if the host fails to detect LUNs:
Determine the connection mode at the front end. If the Fibre Channel switch is connected, check whether the switch mode has been configured.
If the front end uses the Fibre Channel switch, check with the customer that the switch has been correctly configured with zones and assign the storage system and the host to the same zone. If the port WWN is bonded during zone division, check whether the port binding is correct. Alternatively, use optical fibers to directly connect the storage system to the switch and re-scan for LUNs.
