ONTAP or Data ONTAP or Clustered Data ONTAP or Data ONTAP 7-Mode is NetApp's proprietary operating system used in storage disk arrays such as NetApp FAS and AFF, ONTAP Select and Cloud Volumes ONTAP.

Lab 6: Make Use of RAID Redundancy
In this lab, we simulate failures in the RAID redundancy.
Commands used:

Show iSCSI service is running
iscsi status

Show r / w, online, mapped
lun show

Check the status of the initiator group that is mapped to the LUN
igroup show

View the system’s current RAID configuration.
sysconfig -r

Fail the data disk in RAID group 0 (rg0) in aggr1
example: disk fail -i v5.18

Unfail the four drives that are marked as failed.
priv set advanced
*example: disk unfail v5.18
*Repeat this action for each disk

Because the RAID reconstructions are complete and the data on the previously failed drives is no longer needed, wipe the data from these drives.
disk zero spares
