Looking at the various LineOfService options, and the related elements like Storage Pool, Storage Group, I could not figure out a way using which I could set the RAID level of the underlying volume manager running on the Chassis.
There are various RAID levels amongst which I would like to select a particular level while creating a Storage Group.
Which Swordfish construct can be used to specify the RAID Level mapping?
IMHO, since StoragePool shall be a global pool over which the "Volumes" shall be created, the facility to specify RAID settings should be applicable while creating a new Storage Pool. All Volumes then which are part of that StoragePool shall inherit the RAID settings for the StoragePool.
Your suggestion is consistent with some implementations. In others a pool is factory that is able to create multiple types of volumes, file systems, or object stores. There are several possible ways to represent this. It would be good to have your participation in the Swordfish SSM TWG.
