ONTAP 9.13

Before you add a local tier, you can learn about RAID groups and RAID protection levels and policies for local tiers. You can learn about mirrored and unmirrored local tiers and how to quickly zero drives before provisioning them. You also perform a manual assignment of disk ownership before provisioning a local tier.

To add a local tier, you follow a specific workflow. You determine the number of disks or disk partitions that you need for the local tier and decide which method to use to create the local tier. You can add local tiers automatically by letting ONTAP assign the configuration, or you can manually specify the configuration.

For existing local tiers, you can rename them, set their media costs, or determine their drive and RAID group information. You can modify the RAID configuration of a local tier and assign local tiers to storage VMs (SVMs). You can modify the RAID configuration of a local tier and assign local tiers to storage VMs (SVMs). You can determine which volumes reside on a local tier and how much space they use on a local tier. You can control how much space that volumes can use. You can relocate local tier ownership with an HA pair. You can also delete a local tier.

Using different methods, you follow a specific workflow to add capacity. You can add disks to a local tier and add drives to a node or shelf. If needed, you can correct misaligned spare partitions.
