about HBA API : HBA_GetFcpTargetMapping(V2)

blueiris — Mon, 05 May 2008 02:14:15 GMT

when I use HBA_GetFcpTargetMapping(V2) , normally it is fine. But when the target has no LUN0, for example, there is LUN1 and LUN2, the function will fail : stack error!
so I have to reload the my qla2300 driver and the function will work fine again. But without reloading, it fails.
Could anyone know the issue?

You didn't mention what the target is but it's Lun 0 which is also called as Command Lun which facilitates the communication between the host and the target. So it should exist in any case.

In fact I use SCST and qla2340 card.
seeing about this case:
originally there is a lun0 with /dev/disk1 in group1, and in initiator I
call HBA_GetFcpTargetMappingV2, it works ok. But now in target the admin
delete lun0 from group1, but in initiator we call HBA_GetFcpTargetMappingV2
again and it will fail!
What is the problem?
