SSH to a liquid-cooled node and view the BIOS logs. The BIOS logs for liquid-cooled node controllers (nC) are stored in the /var/log/n0/current and /var/log/n1/current directories.
The BIOS logs for liquid-cooled nodes are helpful for troubleshooting boot-related issues.
This procedure requires administrative privileges.
Log in to the node.
SSH into the node controller for the host component name (xname). For example, if the host xname (as defined in /etc/hosts) is x5000c1s0b0n0, then the node controller would be x5000c1s0b0.
ncn# ssh XNAME
Confirm that the hostname is correct for the node being used.

View the logs for n0.
n0 is node 0 on the BMC.
tail /var/log/n0/current
View the logs for n1.
n1 is node 1 on the BMC.
tail /var/log/n1/current
