Stage 6: Checking and testing cluster configuration

Testing takeover and giveback  Top

To test takeover and giveback, complete the following steps.

Step

Action

1

Check the cabling on the cluster interconnect cables to make sure that they are secure.

2

Verify that you can create and retrieve files on both nodes for each licensed protocol.

3

Enter the following command from the local node console:

cf takeover

Result

The local node takes over the partner node and gives the following output:

takeover completed
4

Test communication between the local node and partner node.

For example, you can use the fcstat device_map command to ensure that one node can access the other node's disks.

Example:

filer-1> fcstat device_map

5

Give back the partner node by entering the following command:

cf giveback

Result

The local node releases the partner node, which reboots and resumes normal operation. The following message is displayed on the console when the process is complete:

giveback completed
6

If takeover and giveback...

Then...

Is completed successfully

Repeat Step 2 through Step 5 on the partner node.

Fails

Go to Correcting takeover or giveback failures.
