How to solve the problem that the S12000 storage system can’t identify the WWN number of HP small-size device

Publication Date:  2012-09-18 Views:  135 Downloads:  0

Issue Description

In a bureau start of Shandong Province, the S12000 was connected with the HP SuperDome and VIS host system developed by Huaweisymantec through FC switch. The S12000 can’t identify the WWN number of HP small-size device when it was mapped to HP small-size device with default config, but it can identify the WWN number of VIS system and the VIS system can use the storage space mapped by S12000.
Check the FC switch, we can see that the Zone configure is right, and the WWN number of S12000, VIS, and HP small-size device could be seen.

Alarm Information


Handling Process

Modify the port pattern of FC switch into “F”, the S12000 can identify the WWN number of HP small-size device, and the HP host can normally used the storage space mapped.

Root Cause

In the default configure of S12000, the pattern of connection between host and interface is “FL”, it can also be set “F”. The “FL” is used in the direct connection while “F” is used in connection through FC switch between storage and host.


In the FC connection between host and storage, if the storage can’t identify the WWN number of the host, and there is no problem in the physical connection as well as the correct Zone configuration in FC switch, we should check the work pattern of the storage port.
