Pre-Lab Exercises Introduction Important
The following lab exercises provide the steps for setting up Windows and Linux to interact with the VNX-series storage system through Block and File connectivity. A few important notes! Note 1: Not all screen captures were made on the lab equipment you will be using and therefore may differ slightly from what you will see. Read each lab and step completely before attempting it; do not simply follow the pictures! Note 2: You will be sharing a VNX system with other students to perform the lab exercises. This lab guide and a corresponding Class Configuration Sheet are used together to perform the lab exercises. It is important to follow the naming convention for the objects you create by following the lab guide and referring to your configuration sheet for the unique names. In the lab guide objects or “items” specific to each student are identified with Bold Italic text. The corresponding “value” for the item is located on your specific student Class Configuration Sheet. So when you see Bold Italic text in the lab guide, you are required to use a value for the item that is located on your Class Configuration Sheet. Each lab exercise has a section labled “Preparing for the Lab” and is designed as a tear-out sheet. It lists the objects or “items” that will be identified with the Bold Italic text in the lab guide. You may use this section to record the values for each item from the Class Configuration Sheet. Refer to this tear-out to input the values for the specified items.

Step 3
Action Mount the file system: From your Student Desktop, use PuTTY to open an SSH to the Linux Host Address. Log into the host with the following credentials: logon as: root password: emc2Local! From the terminal window, create a local directory to mount the file system that you have exported via NFS. Type the following: cd / mkdir /fs1
Check the contents of your /fs1 directory. cd
/fs1
ls –al The directory listing should show that the new directory is empty. In a subsequent lab step the directory will be used as a mountpoint for mounting the top-level of an exported file system from the VNX. NFS mount this directory to the exported file system on your Data Mover. Type the following: cd / mount Data Mover Address:/File System 1 /fs1 df (confirm that the mount is listed) cd
/fs1
ls –al Note: By default a new directory is empty. Therefore, when you created your /fs1 directory on the client it was empty. However, after NFS mounting it to your Data Mover, /fs1 is now being redirected to a file system showing lost+found and .etc (hidden) directories.
EMC Educational Services
180
Step 4
Action Create user directory on file system Confirm that you are at /fs1 directory using pwd command. pwd /fs1 List the content of the directory by running the following command: ls – la The directory is no longer empty. When in the directory you are redirected to the remote file system mounted to the directory. Notice that the .etc and lost+found directories are present. These directories are structure present on the top of the VNX file system and should not be disturbed. Create a new directory and name it engineering. mkdir engineering Change the permissions on this directory to 775. This means read, write, and execute for the owner and group, and read and execute for others. chmod 775 engineering Change the owner of engineering directory to epallis. chown -R epallis engineering Change the group of engineering directory to engprop. chgrp -R engprop engineering Verify the new permissions on the directory. ls –l drwxrwxr-x. 2 epallis engprop

Step 7
Action Access the lower-level share: From the Windows server, launch File Explorer which is available from the Desktop view or its taskbar.
From the left side tree, right-click Computer and select the Map network drive option. In the Folder: field, enter the path to the HMARINE_SHARE. The format of the path is: \\\ Where is your CIFS Server and is HMARINE_SHARE Leave all other options on the page at their default settings and click Finish. The share opens and the test_data file create in a previous step is present. Notice the absence of the .etc and lost+found folders that were seen from the top-level share. This lower-level share demonstrates the best practice of preventing users from access and disturbing the .etc and lost+found folders. Open the test_data file and verify its data is present. Add another line of text to the file. Do not save or close the file, just leave the file open in Notepad. The file will be left open for the last part of the lab exercise. Also leave the Remote Desktop connection session open to your Windows server. It will be used in the next part of the lab exercise.

Lab: Part 4 – Move a VDM containing a CIFS Server Step 1
Action Verify Shares: From your Student Desktop system Unisphere session, navigate to Storage > Shared Folders > CIFS and select the Shares tab. If your session is already at this page, refresh the Shares page. The page should display the two CIFS shares created, the top-level share created with Unisphere and the lower-level share created with Microsoft’s Computer Management tool. Note: Use the “Filter” field in Unisphere and input your Student number to limit the display to your shares.
2
Move the VDM to the peer Data Mover:
Navigate to Storage > Shared Folders > CIFS and select the VDMs tab. Select your VDM and click Properties. From the Data Mover drop-down list, select your Peer Data Mover Click OK. A confirmation window opens for you to confirm the VDM move operation. Review the message displayed in the window. Optionally click the details link to view further details of the move operation. Click OK to proceed with the VDM move operation. Review the information displayed on the “VDMs” tab for your VDM. It should display the VDM is now loaded to your Peer Data Mover.
EMC Educational Services
207
Step 3
Action Flush the CIFS client DNS cache: Return to your existing Windows server Remote Desktop session. It is available on your Student Desktop system’s taskbar.
The Windows server is your CIFS client. In the previous part of this exercise, the client established a CIFS session to your CIFS server. The client performed a DNS lookup for your CIFS server and cached that lookup in its DNS cache. When the VDM containing the CIFS server was moved, the CIFS server binds to the interface of the Peer Data Mover and that interface has a different IP address. Therefore to reconnect to the CIFS server, the client’s DNS cache must be flushed so it can do a new DNS lookup for the CIFS server. On your Windows server, open a Command window which is available from the Desktop view or its task bar.
In the command window run the following command: ipconfig /flushdns 4
Access CIFS data after VDM containing CIFS server moves: Return to your open test_data.txt file in Notepad. Add some text to the file and save the changes. When the CIFS server changes its IP address due to the VDM move operation, the existing CIFS session is disconnected. When the client performs a new write operation to the file, the client establishes a new CIFS session and reconnects to the share to perform the write operation to the file. Leave the file open within the Notepad session.
EMC Educational Services
208
Step 5
Action Move the VDM back to the original Data Mover From your Student Desktop system Unisphere session, navigate to Storage > Shared Folders > CIFS and select the VDMs tab.
Select your VDM and click Properties. From the Data Mover drop-down list, select your Data Mover Click OK. In the confirmation window click OK to proceed with the VDM move operation. Review the information displayed on the “VDMs” tab for your VDM. It should display the VDM is now loaded to your Data Mover. 6
Access the CIFS data after the VDM move without flushing DNS:
Return to your existing Windows server Remote Desktop session.
Return to your open test_data.txt file in Notepad. Add some text to the file and save the changes.
The results of this operation can vary depending on how much time has passed since the new CIFS session was established in step 4 above. If enough time has passed for the client DNS cache to expire though its default timeout, the changes to the file will be saved normally. If the client DNS cache has not expired, you will receive an error stating “The specific network name is no longer available.”. The error can be cleared and access to the share returned by flushing the client’s DNS cache or waiting for its normal cache timeout to occur.
On your Windows server close all open applications.
Disconnect from the Remote Desktop by accessing the Logoff Session icon which is available from the Windows server Desktop view or its taskbar.

Appendix: Unisphere Browser and Java Messages
Unisphere is a Java-based web application that is accessed from a browser. The VNX secures the application using industry standard mechanisms to establish a secure http channel between the VNX and the storage administrator’s browser. The VNX uses self-signed certificates for securing the channel. The browser must also have Java installed to run the VNX Unisphere Java applications. When establishing a Unisphere session, the user will encounter a series of security related messages from the browser, from Java and from the VNX itself. The specific messages will vary with different browsers, different versions of Java JRE and with different versions of VNX software. This appendix captures the various messages a user will encounter with the following specific browser, Java and VNX OE software versions. It also details the actions to take to minimize the security messages seen for subsequent Unisphere sessions. Browser: Microsoft Internet Exporer version 10 Java: Version 7 update 25 VNX OE software: 05.33.000.5.015
The first security related message encountered is shown below. The browser message is displayed due to the browser not trusting the VNX self signed certificate. The user must click the Continue to this website (not recommended) action to proceed.
