Optional Power On From the CMC Command Line
Most SGI UV 2000 systems come with a system management node (SMN) and there should be
few reasons for powering on the system from a CMC.
Note: Some basic systems are sold without an SMN and require slightly different administrative
procedures. These “SMN-less” systems are restricted in regards to number of blades and router
options available.
Use the following information if you have a need to power on from a CMC rather than the SMN
CLI or the SGI Management Center GUI. If the SMN is not available you can still boot the system
directly by using the CMC, see “Booting Directly From a CMC”.
Note: The command line interface for the CMC is virtually the same as that for the SMN, with
the exception that the CMC does not have the ability to target a system when multiple systems are
supported from one SMN.
Booting Directly From a CMC
If a system management node (SMN) is not available, it is possible to power on and administer
your system directly from the CMC. When available, the optional SMN should always be the
primary interface to the system.
The console type and how these console types are connected to the SGI UV 2000 systems is
determined by what console option is chosen. To monitor or administer a system through the CMC
network, you will need to establish a mini-USB serial connection to the CMC. See the information
in the following two subsections.
Power On the System Using the CMC Network
You can use a use a direct mini-USB serial connection to the CMC to power on your UV system;
note that this process is not the standard way to administer a system. Use the following steps:
1. Establish a connection (as detailed in the previous subsections). CMCs have their rack and
“U” position set at the factory. The CMC will have an IP address, similar to the following:
172.17.<rack>.<slot>
