Ultra E150 Solaris 2.5.1 Oracle server. was working fine, then started losing network connection. I can see in messages file that it was complaining about another device using its ip address. Though not any longer, though I wonder if that was a red herring. My IT guys have now re-reserved its ip address on the dhcp server. I have restarted it several times but it won't talk to the network. I tried changing its ip address to another reserved one, but Oracle complains, the ip must be embedded in that somewhere. Should the ethernet cable socket flash when connected on this hardware? it doesn't. I tried a different cable, direct into a different hub.
