A set of N8300 installed at a certain site, distributed the LUN mapping to the engine at the storage, there wasn’t the mapped LUN when we scan the data disk on the ISM network management interface.
Map the LUN001 whose LUN IN is 1 to the engine, scan the data disk on the ISM interface of the N8000 again, the outcome is as follow:
The LUN is normal.
Check the status of the LUN mapping on the ISM interface:
We can find that the LUN ID of the LUN002 is 0, however, the LUN ID of the mapping on the storage is requested to distribute from 1 by the operating system of the NAS engine, if takes the 0, the corresponding mapped LUN can’t be identified by the operating system.
