Controller A port 2 = node ID + 4
When one of the pair of controllers in a dual redundant configuration is replaced,
the remaining controller remembers the node ID. When the replacement controller
is installed, the in-place controller tells the node ID to the replacement controller,
and the replacement controller automatically assumes the correct port IDs.
If a situation occurs that requires the node ID to be reset, it can be done through
the CLI by specifying the NODE_ID parameter in the SET controller command.
The node ID must be reset to the number on the enclosure sticker. (The sticker
calls it the worldwide name.) The sticker also contains a checksum, which verifies
the ID number. When the node ID is entered, both controllers assume the correct
port IDs automatically. Figure 2–1 shows the location of the sticker.
