"The controller is disabled because the cache module is not attached"

[Dmitri Minaev]

Hello,

I have a DL180 G6 server with Smart Array P212 RAID controller. The server runs under Ubuntu. After an upgrade from Ubuntu 10.04 to 12.04 utility hpacucli (ver. 8.50-6.0) stopped working. It reported about missing controller. I updated the utility to version 9.10.22.0. Now, the message is:

Smart Array P212 in Slot 1                (sn: PACCP9SXL778  )

CACHE STATUS PROBLEM DETECTED: The controller is disabled because the cache
                               module is not attached. Please re-attach the
                               cache module to re-enable the controller.

 Is this for real, should I start investigating a problem with the cache module? Or is this an incompatibility problem between Ubuntu 12.04 and hpacucli?

Thank you.
