Existing Oracle Solaris EoIB datalinks are disabled after upgrading to firmware version 2.1, and new EoIB datalinks are created.
If vanity naming is in use – During an upgrade to firmware version 2.1, consider that you will need to know the names of the EoIB datalinks prior to the upgrade (for example netX), perform the upgrade, and find the names of the equivalent EoIB datalinks after the upgrade (for example netY). Then disable Oracle Solaris VNICs, VLANs, and IP interfaces that existed over the old datalinks, rename the new datalinks with the old datalink names using the dladm rename-link netY netX command, and bring the VNICs, VLANs, and IP interfaces back up.
If vanity naming is not in use – After the upgrade to firmware version 2.1, consider you will need to recreate the Oracle Solaris VNICs, VLANs, and IP interfaces on the new EoIB datalinks.
