Hi again Hsie, Here is some potentially useful information regarding the 'maintenance' state for the McIDAS ADDE service: http://www.sun.com/msg/SMF-8000-9C Also, here is a reply I sent to a user regarding what I found in a Google search: Here is the Question and Answer pair that see appropriate: Q: What happens when an smf(5) service fails? A: When a service participating in smf(5) fails due to a hardware error such as an uncorrectable memory fault, software error such as a service core dump, or even administrative error such as killing the wrong process, the fault is detected and the service is automatically restarted by smf(5). Any services which depend upon the failing service are also immediately stopped so that they can be restarted when the failing service recovers. Service status is given for all services on the system through the svcs(1) command. If a service cannot be restarted by the system, it is put into the "maintenance" state. The svcs -x command gives as much diagnosis of the failure as possible, including the reason for failure, pointers to log files and man pages, and a summary of other services which are impacted by the failure. A pointer to a knowledge article with further information about possible causes and remedies for the fault is also given. It appears that 'svcs -x' should give you important information on why 'svcs' is not listing the remote McIDAS ADDE service as being online. The command you will need to execute as 'root' is: svcs -x /network/mcidas/tcp More information can be had if the following is run by 'root': svcs -l /network/mcidas-tcp More as I discover additional information.
