for more information.
Most enterprise servers do not have video adapters installed with the machine and often do not provide a method for attaching a physical monitor/keyboard/mouse to get the display output. For this purpose xCAT can assist the system administrator to view the console over a "Serial-over-LAN" (SOL) connection through the BMC.
Configure the correct console management by modifying the node definition:
For OpenPOWER, IPMI managed server: :
chdef -t node -o <noderange> cons=ipmi
For OpenPOWER, OpenBMC managed servers: :
chdef -t node -o <noderange> cons=openbmc
Open a console to compute1
: :
rcons compute1
Note
The keystroke ctrl+e c .
will disconnect you from the console.
xCAT
has been integrated with 3 kinds of console server service, they are
- conserver [Deprecated]
- goconserver
- confluent
rcons
command relies on one of them. The conserver
and goconserver
packages should have been installed with xCAT as they are part of the xCAT dependency packages. If you want to try confluent
, see confluent server </advanced/confluent/server/confluent_server>
.
For systemd based systems, goconserver
is used by default. If you are having problems seeing the console, try the following.
- Make sure
goconserver
is configured by runningmakegocons
.Check if
goconserver
is up and running :systemctl status goconserver.service
If
goconserver
is not running, start the service using: :systemctl start goconserver.service
- Try
makegocons -q [<node>]
to verify if the node has been registered.- Invoke the console again:
rcons <node>
More details for goconserver, see goconserver documentation </advanced/goconserver/index>
.
[Deprecated] If conserver
is used, try the following.
- Make sure
conserver
is configured by runningmakeconservercf
.Check if
conserver
is up and running :[sysvinit] service conserver status [systemd] systemctl status conserver.service
If
conserver
is not running, start the service using: :[sysvinit] service conserver start [systemd] systemctl start conserver.service
- Invoke the console again:
rcons <node>
