Do you want to configure the Shelf Alternate Control Path Management interface for SAS shelves [n]: 5.

Now, let’s reboot the storage system to make our changes take effect. NOTE: Because we only added the admin host setting, we don’t really need to reboot. If this was a production storage system, you might make the change take effect without rebooting by using the source command. system> reboot The setup command automatically updates the following files: /etc/exports – allowing the admin host to mount the root volume. /etc/hosts.equiv – allowing the admin host to be trusted on the storage system (allows rsh commands). /etc/hosts – allowing IP resolution of the admin host. options admin.host – which displays the name of the admin host that was provided during the setup command. If volumes are automatically exported (a feature described later in the course), this setting determines “who” should receive access to the server-generated export. We will now explore these changes.

6.

After the reboot, log in to your storage system. What volumes exist on your storage system? ______________________ Which command did you use to discover the volumes?_______________

List the content of the /etc/exports file in the space provided: HINT: There is a command-line interface command, but you might be able to do it another way. If you issued a command-line interface command, what command did you run?_____________ How do you list what exports are presently in memory? __________________ Remember this file was populated during the storage system’s setup.

8.

Record the IP address and hostname for each entry in the /etc/hosts file as follows: Host1: IP Address:

9.

List the content of the /etc/rc file in the space provided: HINT: Again, there might be more than one way to accomplish this. The /etc/rc file sets up interfaces and loads exports, as well as other configurations, during boot up of the storage system. You modify the /etc/rc file by running setup but you can modify it directly. The /etc/rc file is only executed at boot up. To execute any modification to the /etc/rc, use the source command. system> source /etc/rc This executed the /etc/rc file again. To learn more about the source command, see the manual (man) page. system> man source

If you are not familiar with this technique, refer to the following: Verify your current location # pwd /mnt/system/vol0 If you are not here, within the vol0 mount point, change your directory to this location. Change directory into your assigned storage system’s etc directory. # cd etc Run vi on the exports file. # vi exports Your exports file will now be available in the vi editor and the editor will be in command mode. Scroll down to the last line. Type Shift-A, capital A, to append to the end of the line you are currently on. Enter Return to move to the next line. Type in the following line: /vol/NFSvol/unix_tree -rw=,root= replacing the with your assigned UNIX/LINUX hostname or IP address. Click the ESC button to move out of append mode and back to command mode. Enter :wq to write the file and quit vi. Verify your changes using the cat command. # cat exports ... /vol/NFSvol/unix_tree -rw=host1,root=host1

Who has access to the file, and what are the file permissions? _______________________________________________ i)

Click the Cancel button.

Recall that the mixedtree qtree has a designated security style of mixed. This means that the default security style of a file is the style most recently used to set permission on that file. With mixed security style, the volume or qtree can have UNIX or NTFS file security in play. Because the mixedtree qtree was created when the storage system was multiprotocol mode, the mixed qtree initially inherited the effective security style of the parent volume. 10.

To view the UNIX permissions on the files in this multiprotocol environment, enter the following option at the storage system prompt: system> options cifs.preserve_unix_security on Enabling this option allows you to manipulate a file’s UNIX permissions using the Security tab on a Windows client, or using any application that can query or set Windows ACLs. When enabled, this option causes UNIX qtrees to appear as NTFS volumes. The default for this option is “off.”

TASK 7: REINSTATE THE ORIGINAL SNAPMIRROR RELATIONSHIP In this task, you will resynchronize the SnapMirror relationship from the destination side. Remember that resync can be initiated from different sides of SnapMirror relationship with different consequences. Please refer to the lecture portion of this module for more information. NOTE: This task will only be completed if you are managing the destination storage system within the SnapMirror relationship. STEP ACTION

1.

To reinstate the original SnapMirror relationship, you have to resync it, but this time you will issue the command from the destination storage system. destination> snapmirror resync –S src_hostname:vol3 dst_hostname:vol3 Answer yes or y when prompted to confirm the command.

2.

Verify that the Dataset2 directory is present in the destination volume.

3.

You can check that the original relationship was successfully reinstated by triggering a manual update. But first, copy the Dataset3 directory into the source volume. After the manual update, we will verify whether Dataset3 was mirrored to the destination volume. Trigger a SnapMirror update from the destination volume: destination> snapmirror update vol3 Check that the Dataset3 directory is present in the destination volume vol3.

4.
