about its internal blades, and also (if other IRUs are attached via NUMAlink to the IRU)
information about those IRUs.
Command Options for Power On
The following example command options can be used with either the SMN or CMC CLI:
usage: power [-vcow] on|up [system-SSN]...turns power on
-v, --verbose verbose output
-c, --clear clear EFI variables (system and partition targets only)
-o, --override override partition check
-w, --watch watch boot progress
To monitor the power-on sequence during boot, see the section “Monitoring Power On” on
page 19, the -uvpower option must be included with the command to power on.
Power On the System From the SMN Command Line
1. Login to the SMN as root, via a terminal window similar to the following:
The default password for logging in to the SMN as root is sgisgi.
# ssh -X root@uv-system-smn
root@system-smn>
Once a connection to the SMN is established, the SMN prompt is presented and various
system control commands can be entered.
2. To see a list of available commands enter the following:
root@uv-system-smn>ls /sysco/bin/help
3. Change the working directory to sysco, similar to the following:
root@uv-system-smn>cd /sysco
In the following example the system is powered on without monitoring the progress or status
of the power-on process.When a power command is issued, it checks to see if the individaul
rack units (IRUs) are powered on; if not on, the power command powers up the IRUs and
then the blades in the IRU are powered on.
4. Enter the power on command, similar to the following:
sysco@uv-system-smn>power on
