Requirements when changing a node using array LUNs to stand-alone

After uncoupling storage systems using array LUNs in an HA pair, you might need to perform additional reconfiguration related to Data ONTAP ownership of array LUNs.

The following table summarizes the requirements when uncoupling a storage system using array LUNs from an HA pair.

If you want to... Requirements for uncoupling systems are... Requirements for array LUN assignments to systems are...
Make both systems in the pair stand-alone systems Remove the HA configuration software and interconnect cabling No Data ONTAP reconfiguration of array LUNs is necessary. Each system can continue to own the array LUNs assigned to it.
Remove one system in the pair from service Remove the HA configuration software and interconnect cabling After uncoupling the pair, you must do one of the following:
  • If you want to continue to use the array LUNs for Data ONTAP, reassign the array LUNs owned by the system you are removing to another storage system.
  • Prepare the array LUNs assigned to the system you are removing for use by systems that do not run Data ONTAP.
