Pinned topic High-Availability (HA) for IBM Platform HPC

‏2013-09-16T15:18:20Z | (ha) cluster for high-availability hpc ibm pb

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.
