[gpfsug-discuss] [EXT] Adding ESS to existing Scale Cluster

[Fosburgh,Jonathan]

We've added ESSes to existing non-ESS clusters a couple of times. In this case, we had to create a pool for the ESSes so we could send new writes to them and allow us to drain the old non-ESS blocks so we could remove them.

We are planning to add an ESS GL6 system to our existing Spectrum Scale cluster. Can the ESS nodes be added to existing scale cluster without changing existing cluster name? Or do we need to create a new scale cluster with ESS and import existing filesystems into the new ESS cluster?
