we are setting up two sites replication with GAD volumes.
In order to familiarize with the systems involved, a single Linux HCS VA was deployed for the management of both storage systems ( G200 ) and quorum ( HUS 110 ).
In product documentation we have seen GAD topologies with two HCS systems in active/standby cluster configuration, and we started planning the cluster setup.
Unfortunately, in the "HCS Installation and Configuration Guide", we have found detailed instructions to setup HCS in a cluster environment with Red Hat Enterprise Linux 6.5, while HCS VA is shipped with RHEL 7.2.
All of this raises some questions:
- Is HCS VA cluster setup documented for Red Hat Cluster 7.2?
- Is HCS VA cluster supported?
- Is it safer to install HCS cluter with RHEL 6.5?
Hints and suggestions are welcome.
