Er no the DMAPI was only ever required for HSM as far as I am aware. Now while HSM is a form of tiering, in GPFS parlance tiering generally referred to disk pools of varying "speeds", with file placement and movement being done via the policy engine. I still remain to be convinced that tiering to some third party cloud provider will ever be cost effective mind you. JAB. -- Jonathan A.
