Claim:
A remote power management method for use in a multi-node data processing system, comprising: configuring the system to include at least one multi-node partition; determining a unique identifier associated with each network interface card (NIC) in the partition; based at least in part on the determined NIC identifiers, modifying wake-on LAN (WOL) filters of each NIC in the partition to include at least one WOL filter common to all of the NIC's in the partition, wherein a WOL packet corresponding to the at least one common WOL filter produces a reset on the corresponding node such that each partition node is reset in response to the WOL packet; wherein determining the unique identifier comprises determining the media access control (MAC) address of each NIC in the partition; and wherein modifying the WOL filters comprises including in each NIC a WOL filter corresponding to each of the determined MAC addresses such that a WOL packet addressed to any NIC in the partition is accepted by each NIC in the partition.
