Replace the Destage Control Power Module containing the NVRAM11 battery - AFF
A900
To hot-swap a de-stage controller power module (DCPM), which contains the NVRAM11
battery, you must locate the failed DCPM module, remove it from the chassis, and install
the replacement DCPM module.
You must have a replacement DCPM module in-hand before removing the failed module from the chassis and
it must be replaced within five minutes of removal. Once the DCPM module is removed from the chassis, there
is no shutdown protection for the controller module that owns the DCPM module, other than failover to the
other controller module.
