When using the sideband feature on the Oracle ILOM X4170-M2/ZFSSA-controller to connect to the management network through the Oracle Switch ES1-24, the port might not link up after the host is shut down. This issue results in loss of access to the node.
Workaround: Explicitly set the speed to 100 Mbps on the switch port where the X4170-M2/ZFSSA-controller is connected. For example, if the port is being used in ex 0/2, run these commands to set the speed to 100 Mbps.
SEFOS# config terminal SEFOS(config)# interface extreme-ethernet 0/2 SEFOS(config-if)# shutdown SEFOS(config-if)# speed 100 SEFOS(config-if)# no shutdown SEFOS(config-if)# end SEFOS# write startup-config
