Testing F800 series clusters

Testing takeover and giveback  Top

To test your configured cluster, complete the following steps.

Step

Action

1

Verify the network addresses by entering the following command from one node:

ifconfig -a

Result

The local node and partner node IP addresses are listed.

2

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

3

Enable the clustering licenses by entering the following command on the local and partner nodes:

license add xxxxx 

xxxxx is the license code for your cluster.

Note
If you are using a version of Data ONTAP earlier than 6.4, the command is license option=code.

Result

Clustering is enabled on your system.

4

From the same node, enter the following command:

cf enable

Result

Takeover of the partner node is enabled.

5

Run the cluster configuration checker (cf-config-check.cgi) script, as described in Setting options and parameters with the cluster configuration checker.

6

Test communication between the local node and partner node.

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

Example:

filer-1> fcadmin device_map
Loop Map for channel 8: 
Translated Map: Port Count 32

                Shelf 3:  30  29  28  27  26  25  24 
                Shelf 4:  38 XXX XXX  35  34  33  32 
                Shelf 5: XXX XXX XXX  43  42  41 XXX

                Shelf 7: XXX XXX  60  59  58 XXX XXX 

 
Loop Map for channel 7b:

                  7  16  17  18  19  20  32  33  34  35

                Shelf 4:  38  37  36  35  34  33  32 
7

From the local node console, enter the following command and verify that the partner node halted:

cf takeover

Result

The local node takes over the partner node. You see a message similar to the following:

takeover completed
8

Make sure that all clients and client applications can access data.

9

From the same node, enter the following command:

cf giveback

Result

The partner node reboots and functions normally. A successful giveback ends with the following message on the local node:

giveback completed
10

Repeat Step 1 through Step 9 on the other node.
