Replacing a PCIe card

To replace a PCIe card, you must disconnect the cables from the cards, remove the SFP and QSFP modules from the cards

before removing the riser, reinstall the riser, and then reinstall the SFP and QSFP modules before cabling the cards.

About this task

• You can use this procedure with all versions of ONTAP supported by your system

• All other components in the system must be functioning properly; if not, you must contact technical support.

Steps

1. Shutting down the impaired controller on page 1

You can shut down or take over the impaired controller using different procedures, depending on the storage system hardware

configuration.

Shutting down the impaired node

To shut down the impaired node, you must determine the status of the node and, if necessary, take over the node so that the

healthy node continues to serve data from the impaired node storage.

Before you begin

• If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy node shows

false for eligibility and health, you must correct the issue before shutting down the impaired node.

ONTAP 9 System Administration Reference

Steps

1.

Check the MetroCluster status to determine whether the impaired node has automatically switched over to the healthy node:

2. Depending on whether an automatic switchover has occurred, proceed according to the following table:

If the healing is vetoed, you have the option of reissuing the metrocluster heal command with the -override-vetoes

parameter. If you use this optional parameter, the system overrides any soft vetoes that prevent the healing operation.

4. Verify that the operation has been completed by using the metrocluster operation show command.

Example

6. Heal the root aggregates by using the metrocluster heal -phase root-aggregates command.

Example

If the healing is vetoed, you have the option of reissuing the metrocluster heal command with the -override-vetoes

8. On the impaired controller module, disconnect the power supplies.

Removing the controller module

You must remove the controller module from the chassis when you replace the controller module or replace a component inside

the controller module.

Steps

organized.

5. Remove the cable management device from the controller module and set it aside.

6. Press down on both of the locking latches, and then rotate both latches downward at the same time.
