I have a E450 running Solaris 7 which hangs with solid Acitvity LED light. No keyboard lights, no other lights, no crash dump, nothing in auditing. I can get the machine backup up and responsive by either cycling power or pulling the keyboard plug and replugging it in. No response to L1A.
What else should I check?
No, not under maintenance; can't upgrade Solaris versions, etc.
