ID Chip Feature

When you replace a NEM, each of the 10 HBAs and 20 FC ports on the NEM will be assigned new port and node worldwide names (WWNs).To retain the existing WWNs you can remove the ID chip from the NEM that failed and install it on the replacement NEM. Please ensure that each of the 10 individual HBAs on the NEM are running firmware version 2.70x4 or “a” releases 2.72a0 or later.

If you replace a NEM and do not swap the ID chip, new WWNs will be assigned to each of the 10 HBAs and 20 FC ports; thus, requiring you to update SAN components, such as FC switches and storage arrays, with the new values.

Note – If a HBA with firmware older than 2.70x4 or "a" release 2.7a0 is replaced, it will be assigned new WWNs.

See the following Emulex documents for information on how to determine and update to the firmware:
