[INTERNAL] How to create iSCSI VTL in DR4300 then add it as a device target in Netvault Backup? (4041516)

Creating an iSCSI VTL container for NetVault Backup

1. Login to the the DR and select Containers in the left navigation area, and then click Create at the top of the page.

2. Enter the container name, select the Virtual Tape Library (VTL) option, and click Next.

3. Select the iSCSI Access Protocol. Specify the DMA Access Control by providing the storage node / media node IP Address, IQN or FQDN. For NetVault, you must also specific Auto as the Marker Type. Click Next.

4. Finalize VTL creation by clicking Create a New Container

Configuring the iSCSI target – Windows 1.

1.Configure the iSCSI Initiator Software for Windows by providing the IP or FQDN of the DR Series system in the Quick Connect, Target field. Click Quick Connection to open the Quick Connect dialog box, which indicates a connection was made but is set as inactive.

2. Close the dialog box and proceed by selecting the newly discovered target. This target will have an Inactive Status as it requires authentication parameters to be provided for iSCSI logon. Select the Target from the list, click the Connect button, and then in the Connect To Target dialog box, click the Advanced button.

3a.In Advanced Settings, select to Enable CHAP log on and enter the User Name and Target Secret / Password. Select OK. Refer to Appendix A for further details about accounts and credentials.

3b.The iSCSI target should now appear as connected, and device discovery can now proceed.

4. Open the Server Manager Snap-in and verify that the newly connected devices show up in the Device Manager. Verify that the STK Library and IBM Ultrium-TD4 Device Drivers are installed.

Note: Refer to the article at http://catalog.update.microsoft.com/v7/site/home.aspx for information about acquiring Microsoft Device Drivers, e.g., StorageTek Library Drivers.

Configuring the iSCSI target – Linux

Before you begin this procedure, ensure that the iSCSI initiator is installed (iscsi-initiator-utils).

For example: yum install iscsi-initiator-utils ; /etc/init.d/iscsi start To configure the iSCSI target for Linux, follow these steps.

1. Add the CHAP Authentication details for the DR Series system on the Linux Initiator as follows:

a. Edit /etc/iscsi/iscsid.conf and un-comment the following line: node.session.auth.authmethod = CHAP

b. Modify the following lines: # To set a CHAP username and password for initiator # authentication by the target(s), uncomment the following lines: node.session.auth.username = iscsi_user node.session.auth.password = St0r@ge!iscsi

2. Set the Discovery Target Node(s) by using this command: iscsiadm -m discovery -t st -p For example: iscsiadm -m discovery -t st -p 10.8.230.108

3. Enable logon to the DR Series system iSCSI VTL target(s) by using the following command: iscsiadm -m node --portal --login

For example: iscsiadm -m node --portal "10.8.230.108:3260" --login

4. Display the open session(s) with DR VTL(s) by using the following command: iscsiadm -m session For example: iscsiadm -m session = tcp: [8] 10.8.230.108:3260,1 iqn.1984- 05.com:dr4000.3071067.interoprhel52n1.30

5. Review dmesg or /var/log/messages for details about the tape devices created upon adding the DR Series system iSCSI VTL.

Configuring NetVault Backup to use the newly created iSCSI VTL

1. Access the Storage Configuration Wizard menu within the NetVault Administration interface. Select the Add Storage Devices button and then proceed to the Tape library/ medium changer submenu.
2. Select the NetVault node that has the iSCSI device configured, and, after the scan has completed, select the tape library to be added. Click Next to add the iSCSI tape library.
3. When the tape library has been added, click the Create Backup job… button to commit the library. The VTL should show up ready for use.
4. Label all the media with labels and place them in their respective media groups for use
