Things to know:
The firmware update process from Lenovo:
During an automatic code update, each node of a working pair is updated sequentially. The node that is being updated is temporarily unavailable and all I/O operations to that node fail. As a result, the I/O error counts increase and the failed I/O operations are directed to the partner node of the working pair. Applications do not see any I/O failures. When new nodes are added to the system, the update package is automatically downloaded to the new nodes from the Lenovo Storage V7000 system.
