Connect to the serial console of a System p compute node
Access the serial console of a System p compute node from the command line.
Note: The serial
console must be enabled before connecting to the serial console of
a System p compute node. Refer to Enable serial console
support for IBM Flex System p260 and p460 compute nodes.
Before you begin
In order for serial console to work properly with System p® nodes, the following
requirements must be met:
- The conserver daemon must be running on management node. To check
whether the conserver daemon is running, run the following command:
# service conserver status conserver (pid XXXXX) is running... - The hardware server daemon (hdwr_svr) running
on management node must be connected to the compute node's FSP and
must be established.
- To check whether this connection exists, the state must be set
to LINE UP. Run the following command:
# lshwconn node-name node-name: sp=primary,ipadd=FSP-IP-address,alt_ipadd=unavailable,state=LINE UP - If the hdwr_svr process loses the connection,
you can reconnect it using the following commands:
where node-name is the name of the node.# rmhwconn node-name # mkhwconn node-name -t
- To check whether this connection exists, the state must be set
to LINE UP. Run the following command:
- The compute node must be powered on. To check whether node is
powered on, the node's state must be set to on.
Run the following command:
# rpower node-name state node-name: on
