I am responsible for IBM HPC cluster.
I have a problem with High-Availability (HA) operation. head node is considered as the faileover node.
There was a possibility to change head node as a master node.
for information, when I run the head node, and try to execute the command: hpc-ha-tool so I have the following message:
"Only HPC node heade May run hpc-ha-tool."
really, I can not find an explanation for this error message.
thank you in advance for your help.
