Liquid leak problem
Liquid leaks can be identified through the following practices:
• If the server is on remote maintenance,
– A Lenovo XClarity Controller event shows:
FQXSPCA0040N: Liquid is leaking from open loop [CoolingSensorName].
– Lenovo XClarity Controller has defined lots of system conditions as IPMI sensors. Users can use IPMI
commands to check system running status. Here are examples of executing ipmitool, an open-source
common tool which follows Intel’s IPMI standard. Check for liquid leakage status with command lines
as shown.
–
The event logs shown with the parameter sel elist.
–
Liquid Leak ׀ EAh ׀ ok ׀30.1׀ Transition to Critical from less severe
The status of all sensors can be fetched with the parameter sdr elist. If liquid leakage happens, the
log above will show up.
