Even with latest HP SAS expander firmware version 2.10 (CP022989, Sep 9th 2014,
PUF21000.bin e898facebe75c180c0a9e7d521d0285a), no drives attached, only the
7805H with one cable SFF-8643 to SFF-8088 (0.5 meter in length) to the external
(1C,PORT1C) of the expander, there are these failure messages:
