Under certain circumstances, a Sun Blade X8400 server blade will not be listed in its chassis group, but will be listed as a separate managed server with the status unreachable.
This problem can be caused by any one or more of the following situations:
The Sun Blade X8400 server blade has been removed from the Sun Blade X8000 chassis
The Sun Blade X8400 server blade SP is not accessible by N1 System Manager due to SP problems, IP address reassignment, or other management network problems
To resolve this problem:
Ensure the IP address assigned to the Sun Blade X8400 server blade is correct.
Ensure that the Sun Blade X8400 server blades can be accessed using ssh.
Physically check the blade, and if necessary, power cycle the blade SP. If the blade SP has hung, you will need to go to the blade to power cycle the SP.
After you have verified that the Sun Blade X8400 server blade is accessible using N1 System Manager and standard access protocols, refresh the server blade using either of the following two methods:
Type set server server id refresh in the N1 System Manager browser interface command line prompt where server id is either the Sun Blade X8400 server blade IP address or the name you have assigned to the Sun Blade X8400 server blade.
Type n1sh set server server id refresh in a root login terminal window on the management server where server id is either the Sun Blade X8400 server blade IP address or the name you have assigned to the Sun Blade X8400 server blade.
