Storage Groups
A single-host system connected to the CX3 Series storage system will be added to a dedicated
Storage Group. Multi-system cluster nodes will be added to a shared resource Storage Group for
disk access. EMC does not provide a Storage Group naming standard as a best practice.
Create a Storage Group
Storage Groups must be defined before you can assign LUNs to a specific host. Table 4
describes the user-defined and default parameters to create a Storage Group.
