loss of redundant power or cooling:

From the book IBM Enhanced SSA 4-Port Adapter User's Guide and Reference (SC23-1782-00) :

Observe the Status column on the screen. If the status of any pdisk is ‘Power’,
that pdisk has detected a loss of redundant power or cooling. In the example
shown here, pdisk4 has detected such a loss.

looks like you have lost a psu or fan in this drawer.
2 power supplies at the back, three fans at the front, check the lights.
the drawer "should" displat the failed unit on the orange display on the front of the drawer, fan1 / fan2 / fan3 / psu1 / psu2, to let you know which has failed.
