Control nodes via IPMI
Power management via IPMI
The following nodes can be controlled via IPMI tool from command line:
np04-srv-00[1-4,8-9], np04-srv-0[10-19,21-30]
The IP address used for each node's IPMI interface is in the format of
192.168.100.1xx
, where xx is the node number, e.g.
192.168.100.101
for
np04-srv-001
and
192.168.100.130
for
np04-srv-030
.
To control or check the power of a node (taking
np04-srv-026
as an example), you will need to be either on
np04-srv-009
or
np04-srv-010
as they are "IPMI" head nodes (with NICs connected to the IPMI switch):
ipmitool -I lanplus -U admin -H 192.168.100.126 chassis power status # change status to 'reset', 'off' or 'on' to control the power
You will be prompt for a password. Ask in the
#sysadmin
slack channel for that info (
NOTE:
np04-srv-027
has a different password due to the default password pattern requirement is stricter than other nodes with older hardware). You can give an
-f PASSWORD_FILE
option to the
ipmitool
command used above. The PW file can be found under
/root
on
np04-srv-009
(
/root/ipmipasswd
and
/root/ipmipasswd_027
).
Connect to serial consoles
The ways to connect to serial consoles are different due to different hardware types we have.
Most of the Dell nodes provide SOL (Serial Over Lan) access via SSH. For those nodes, you can do
ssh -l admin 192.168.100.1xx
, and then type
console com2
to connect to the serial console. (Use "Ctrl"+"\" to exit from the console and get back to SSH prompt).
For nodes with Intel or
SuperMicro mother boards, the most reliable way to see the console is to start a browser from
np04-srv-009
(recommend to run a VNC server and connect to it in this case), and open
192.168.100.1xx
in the address bar. There you can navigate to a page which provides a button for launching SOL.
The newest nodes (
np04-srv-0[28-30]
) comes with VNC server for the console. You can connect to them from
np04-srv-009
using
vncviewer 192.168.100.1xx:5901
with the same password as the IPMI tool (replace "xx" by 28, 29, or 30).
