Move the ADC service

You can move the ADC service to another Storage Node on the same site.

Before you begin

  • You are signed in to the Grid Manager using a supported web browser.

  • You have Maintenance or Root access permission.

  • The source node contains the ADC service.

  • The target node doesn't contain the ADC service.

  • The target node is either a metadata-only or combined (metadata and object data) node.

  • The source node and target node are on the same site.

About this task

Use the Move ADC procedure when you want to:

  • Decommission a Storage Node that hosts the ADC service

  • Convert a Storage Node that hosts the ADC service to a data-only Storage Node

When you want to decommission a Storage Node or convert a Storage Node to a data-only node, first you might need to use the Move ADC procedure. You'll need to ensure that the ADC quorum is maintained.

This procedure moves the ADC, IDNT, ACCT, and RSM services from one Storage Node to another on the same site. The RSM, IDNT, and ACCT services are dependent on the ADC service, so they automatically move when the ADC service moves.

Steps

  1. Record the node IDs of the source and target nodes.

    In the Grid Management API, the source node ID is referred to as sourceNodeId. The target node ID is referred to as targetNodeId.

  2. From the top of the Grid Manager, select the help icon and select API documentation.

  3. Select Go to private API documentation.

  4. Select the POST /private/move-adc/start operation. Refer to Issue API requests for more information.

    During the procedure, the two nodes will reboot in sequence. The source node reboots first, followed by the target node.

  5. You can use GET /private/move-adc to monitor the procedure. If errors occur, select POST /private/move-adc/retry to retry the procedure.

  6. Download a recovery package after completing this procedure.
