Test Storage Controller Failover; Test Mpio; Clean Up Test Volumes - Dell Storage Center SCv2000 Deployment Manual

3. Create a folder on the TestVol2 volume, copy at least 2 GB of data to the folder, and verify that the
data copied successfully.

Test Storage Controller Failover

Test the Storage Center to make sure that a storage controller failover does not interrupt IO.
1. Connect to the server, create a Test folder on the server, and copy at least 2 GB of data into it.
2. Restart the top storage controller while copying data to verify that the failover event does not
interrupt IO.
a. Copy the Test folder to the TestVol1 volume.
b. During the copy process, restart the top storage controller (the storage controller through which
TestVol1 is mapped) by selecting it from the Hardware tab and clicking Shutdown/Restart
Controller.
c. Verify that the copy process continues while the storage controller restarts.
d. Wait several minutes and verify that the storage controller has finished restarting.
3. Restart the bottom storage controller while copying data to verify that the failover event does not
interrupt IO.
a. Copy the Test folder to the TestVol2 volume.
b. During the copy process, restart the bottom storage controller (the storage controller through
which TestVol2 is mapped) by selecting it from the Hardware tab and clicking Shutdown/Restart
Controller.
c. Verify that the copy process continues while the storage controller restarts.
d. Wait several minutes and verify that the storage controller has finished restarting.

Test MPIO

Perform the following tests for a Storage Center with Fibre Channel or iSCSI front-end connectivity if the
network environment and servers are configured for MPIO. Always perform the following tests for a
Storage Center with SAS front-end connectivity.
1. Create a Test folder on the server and copy at least 2 GB of data into it.
2. Make sure that the server is configured to use load balancing MPIO (round-robin).
3. Manually disconnect a path while copying data to TestVol1 to verify that MPIO is functioning
correctly.
a. Copy the Test folder to the TestVol1 volume.
b. During the copy process, disconnect one of the paths and verify that the copy process continues.
c. Reconnect the path.
4. Repeat the previous steps as necessary to test additional paths.
5. Restart the storage controller that contains the active path while IO is being transferred and verify
that the IO process continues.
6. If the front-end connectivity of the Storage Center is Fibre Channel or iSCSI and the Storage Center
is not in a production environment, restart the switch that contains the active path while IO is being
transferred, and verify that the IO process continues.

Clean up Test Volumes

After testing is complete, delete the volumes used for testing.
1. Connect to the server to which the volumes are mapped and remove the volumes.
2. Connect to the Storage Center using the Dell Storage Client.
3. Click the Storage tab.
