Replacing a failed drive when using SW RAID

Contributors dmp-netapp Download PDF of this topic

When a drive fails using software RAID, ONTAP Select uses a spare drive (if one is available) and starts the rebuild process automatically. This is similar to how ONTAP on FAS and AFF works. However, if no spare drive is available, you need to add one to the ONTAP Select node.

Both the removal of the failed drive and the addition of a new drive (marked as a spare) must be performed through ONTAP Deploy. Attaching a drive to the ONTAP Select VM using vSphere is not supported.

Identify the failed drive

After a drive fails, use the Deploy utility CLI to identify the disk that failed.

Steps
  1. Sign in to the Deploy utility CLI using the administrator account.

  2. Identify the disk that has failed.
