Due to the power failures on 20th Dec, the department fileservice has suffered some damage, and there is a non functional management interface. This needs to be repaired or replaced. This should *not* be disruptive to users, as per Netapp. But it does involves reseating or replacing a motherboard on one of the nodes, so please be forewarned that one of the clusters will not be running in HA mode during the replacement.
