Possible Causes
One of the following causes may arouse the failure of discovering LUNs on the AS:
l LUNs are incorrectly mapped.
l The rate of the FC HBA card is inconsistent with that of the FC host port.
Fault Diagnosis
You can determine the cause for the fault through the following procedure:
l Cause 1: LUNs are incorrectly mapped.
1. In the navigation tree, choose the Logical View tab.
2. Expand the All RAID Groups node.
3. Click the LUN whose information is to be viewed.
4. Query the information about the LUN mapping.
5. If the actual information about the LUN mapping is different from the assigned
information in advance, you can determine that LUNs are incorrectly mapped.
l Cause 2: The rate of the FC HBA card is inconsistent with that of the storage system FC
host port.
1. Query the rate of the FC HBA card on the AS.
2. In the navigation tree, choose the storage device whose FC host port is to be viewed.
3. On the menu bar, choose Configuration > FC Host Port Managment... to go to the
FC Host Port Management interface.
4. Query the rate of the FC host port on the AS and the storage system.
5. If the rates are inconsistent, you can determine that the rate of the FC HBA card is
inconsistent with that of the storage system FC host port.
Procedure
l Cause 1: LUNs are incorrectly mapped.
1. Delete original mappings.
2. Map LUNs to the correct AS.
3. Rescan the LUNs on the AS. Then, LUNs are discovered on the AS.
l Cause 2: The rate of the FC HBA card is inconsistent with that of the storage system FC
host port.
1. Adjust the rate of the FC HBA card to be consistent with that of the storage system
FC host port.
2. Rescan the LUNs on the AS. Then, LUNs are discovered on the AS.
