Hi
I happened something different caused by SAS HBA.
Adaptec 6405H can not understand Queue full message send by Disks.
Perhaps, normally, any other HBA receive Queue full message from SAS disks,
it will wait send some command to disks.
But Adaptec 6405H is not wait send command to disks,
so, happen disk time out.
I think driver or firmware's bug,because other HBA like using mpt3sas ,
is not happened.
If you need,perhaps I will give SAS bus trace.
Cheers.
