Considerations for using FlexShare in storage systems with a high-availability configuration

If you use FlexShare on storage systems with a high-availability configuration, you must ensure that FlexShare is enabled or disabled on both nodes. Otherwise, a takeover can cause unexpected results.

After a takeover occurs, the FlexShare priorities you have set for volumes on the node that was taken over are still operational. The takeover node creates a new priority policy by merging the policies configured on each individual node. For this reason, you should ensure that the priorities you configure on each node will work well together.
Note: You can use the partner command to make changes to FlexShare priorities on a node that has been taken over.
