First available in ONTAP 9.4, inactive data reporting (IDR) is an excellent tool for determining the amount of existing inactive (cold) data that can be tiered from a high-performance SSD aggregate to low-cost object storage.
IDR uses a 31-day cooling period to determine which data is considered inactive.
IDR is displayed on the Storage Tiers page in OnCommand System Manager.
IDR is enabled by default on FabricPool aggregates, but more importantly, especially for those considering taking advantage of FabricPool for the first time, you can enable IDR on non-FabricPool aggregates.
Note: IDR cannot be enabled on aggregates where FabricPool cannot be enabled (for example, root, HDD aggregates, NetApp MetroCluster, and so on).
From the ONTAP CLI, complete the following steps:
