You can configure ONTAP to automatically assign disk ownership according to a disk's stack, shelf, or bay. If configured, automatic disk ownership assignments occur 10 minutes after system initialization and every five minutes during normal system operation.
Before you begin
- Your system must adhere to the requirements for automatic disk ownership.
- If you have multiple stacks or shelves that must have different ownership, one disk must have been manually assigned on each stack or shelf so that automatic ownership assignment works on each stack or shelf.
About this task
The behavior of the default autoassignment policy depends on the system model. For entry level models, the default policy is equivalent to the bay policy. For all other systems, it is equivalent to the stack policy.
Steps
- Configure automatic disk assignment: storage disk option modify -autoassign-policy autoassign_policy
- Use stack as the autoassign_policy to configure automatic ownership at the stack or loop level.
- Use shelf as the autoassign_policy to configure automatic ownership at the shelf level.
- Use bay as the autoassign_policy to configure automatic ownership at the bay level.
- Verify the automatic assignment settings for the disks: storage disk option show
