You can remove a drive from a cluster using the NetApp Element Management extension point. You might do this when reducing cluster capacity or preparing to replace drives nearing the end of their service life. Removing a drive takes the drive offline. Any data on the drive is removed and migrated to other drives in the cluster before the drive is removed from the cluster. The data migration to other active drives in the system can take a few minutes to an hour depending on capacity utilization and active I/O on the cluster.
When you remove a drive in a Failed state, the drive is not returned to Available or Active states. Instead, the drive is unavailable for use in the cluster.
