Hi Greg,

The SSID 0x0289 correspond to the recent CL2600/CL2800 servers.  These servers
leveraged Proliant hardware but are targeted to a different market segment
with different requirements.  They also come with a different firmware base.

Based upon the targeted market needs, these server de-featured certain
aspects of Proliants with this being one.

As a result, the linux hpilo driver still claims the hardware but
is not functional.

We decided to blacklist the driver to reduce confusion to customers.

Matt will update the documentation in the second version of the patch set.

Hope this helps.

Take care,

Jerry
