Storage Foundation concept
Colleagues, I've qestion about concept how to organize Storage Groups.
Situation look like - EMC storage gives luns for SFORA for Oracle RAC 2 node cluster. VxVS manges 4 storage groups. In each Storage Groups is from 5 to 17 luns (~1TB each). Capacity volumens created on top of this SG is near full. My question is - what is the better solution create new SG
1.add new luns -> create volumens (for Oracle tablespaces) or
2.add new luns to exiting SG -> resize volumens -> resize vxfs? What are advantages and drawback this solutions?
