Re: need to know whether HMC works as a fence device in RHEL 5.32009-12-03T14:31:08Z in response to RajbatraAn HMC is not a compute (user access) system. Over-simplifying, it is simply the management facility for controlling Power systems and the associated LPARs. (That said, the HMC does do a lot of cool things for managing the systems, partitions and the virtualization of the systems).
I'm not that familiar with the RedHat cluster suite or the concept of fencing within that world, but I'm thinking that it has something to do with the cluster global file system and access to cluster resources... which would be controlled via running as either additional partitions or systems.
We are interested in more details of how you're configuring this, so feel free to post more details here.
