Deployment Guide

Test Basic Connectivity

Verify basic connectivity by copying data to the test volumes.

1. Connect to the server to which the volumes are mapped.

2. Create a folder on the TestVol1 volume, copy at least 2 GB of data to the folder, and verify that the data copied successfully.

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 I/O.

About this task

CAUTION: When testing storage controller failover, do not restart a storage controller by pulling it out and reseating it.

Instead, restart the storage controller using Dell Storage Manager Client.

NOTE: Before restarting a storage controller in this task, put the storage controller into maintenance mode. This mode

suppresses alerts that may generate due to the storage controller restart.

Steps

1. Connect to a 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 a test volume to verify that the storage controller failover event does

not interrupt I/O.

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 a test volume to verify that the storage controller failover event

does not interrupt I/O.

a. Copy the Test folder to the TestVol2 volume.

b. During the copy process, restart the bottom 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 front-end SAS 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 I/O 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 I/O is being transferred and verify that the I/O 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 I/O is being transferred, and verify that the I/O process

continues.
