Install a virtual tape library

Installation Process of the virtual tape library: 1. create virtul tape library. <virtual library for IBM utrium 3> 2. create virtual tape <specify the tape size and compression mode> 3. create a San client to enable the inventory card of the virtual database to specify the WWN Number of the memory card of the management server of the virtual database in target mode. Specify the one-to-one correspondence between the memory card of the virtual database and the memory card of the Management Server. 4. A tape drive is found on the management server.

1. create virtual libraries select the tape library that you are emulating.

If you have a physical tape library, you need to create a virtual tape library that resembles it. this way the virtual tapes will use the same format as those of the physical tapes. this is important for importing and exporting functions and guarantees that your backup application will accept the tapes. if you are using the automated tape caching option, you will only see your physical tape libraries listed. select the check box and the system will automatically match your physical library. you will have to enter information about the tape drives in your library, including: * barcode information * tape properties such as tape capacity on demand and maximum tape capacity. if you are using the single instance repository option (SIR), it is highly recommended that you use the tape capacity on demand option. * If you are using the Automatic Tape caching option, you will have to select the type of data migration triggers that you want to set and specify when the data that has been migrated to physical tape can be deleted to free up cache disk space. * if you are not using the Automatic Tape caching option, you will need to determine if you want to use auto archive or auto replication for this virtual library. refer to 'create virtual tape libraries' for detailed information about creating virtual tape libraries and 'Automated tape caching' for detailed information about processing the Automatic Tape caching option. after you create a virtual tape library you will be prompted to create new virtual tapes. refer to 'create virtual tapes' for detailed information about creating virtual tapes.

2. create virtual tapes you can create virtual tapes in the following two ways: * use the Configuration Wizard-if you have already configured your system, you can launch the wizard by right-clicking on the virtualtape library system object in the console and selecting Configuration Wizard. * Right-click on a virtual tape library or on the tapes object and select new tape (s ).

The create virtual tape Wizard will vary depending on whether or not you have enabled the advanced tape creation method (set in tools --> console options ). 1. (Advanced tape creation only) Select how you want to create the virtual tape (s ). custom lets you select which physical device (s) to use and lets you designate how much space to allocate from each. express automatically creates the resource (s) for you using available device (s ). if you select Express, you can create multiple virtual tapes at the same time. 2. (Advanced tape creation only) specify which physical device shoshould be used to create the virtual tapes. storage space is allocated from the local server even if this server is part of a multi-node group. 3. if auto archive is enabled for the virtual library, select the physical tape (s) You want to match. this enables you to have a physical tape with a barcode that matches your virtual tape. this is important for exporting functions. 4. if auto replication is enabled for the virtual library and you want it enabled for this/these tapes, select the target server. you will be asked to confirm the hostname/IP address and indicate how long the system shocould attempt to replicate data before timing out and how often it shocould attempt to retry before skipping a scheduled replication. then, indicate if you want to use the compression and/or encryption options. the compression option provides enhanced throughput during replication by compressing the data stream. the encryption option secures data transmission over the network during replication. 5. depending upon which method you selected, specify the size of the tape (s), name, and number of tapes to create.

 

6. (Advanced tape creation only) If desired, set a barcode range for the virtual tapes you are creating.

7. verify all information and then click Finish to create the virtual tape (s ).

3. Create a San client to enable the VM to bind the database to the target mode. When I open the BIND database, a port is automatically set to the target mode.

This step allows you to select the type of clients (backup servers) to which you will be assigning a tape library. refer to 'add SAN clients (backup servers) 'for detailed information about adding clients. after completing the Configuration Wizard, if you need to add configuration Note: new clients, you can right-click on virtualtape library system and select Configuration Wizard or you can right-click on the SAN clients object and select Add. add SAN clients (backup servers) You can add SAN clients in the following two ways: * use the Configuration Wizard-if you have already configured your system, you can launch the wizard by right-clicking on the virtualtape library system object in the console and selecting Configuration Wizard. * Right-click on the SAN clients object and select Add. after launching the wizard, follow these steps to continue: 1. enter the client name. 2. select the protocol (s) being used by the client.

 

Specify the WWN Number of the memory card of the Management Server with the virtual library (which can be seen from the BIOS of the backup server) for the fiber channel clients, click Next and select the initiator wwpn for the client. note that if the client wwpn is in a zone, it will automatically let you select initiators only from that zone. in addition, if there is only one initiator wwpn in the client, VTL will automatically select it for you and the dialog will not be displayed. click Next and set fibre channel options. enable volume set addressing may be required for particle Fiber Channel clients, such as HP-UX clients that require VSA to access storage devices. select IBM I-series server support if you have a licensed iseries client. select enable celerra support if you have a licensed EMC celerra client. for iSCSI clients, specify if the client is a mobile client. A mobile client is simply a username and password that can be used to authenticate to the VTL server from any iSCSI client machine. if this a mobile client, you will have to select mobile users on the next dialog. if this is a stationary (not mobile) client, click Next and select the initiator that the client uses. if the initiator does not appear, you can manually add it. click Next and add/select users who can authenticate for this client. when you add users, you will have to enter a name and password for each. if you select allow unauthenticated access, The VTL server will recognize the client as long as it has an authorized initiator name. with authenticated access, an additional check is added that requires the user to type in a username and password. more than one username/password pair can be assigned to the client, but they will only be useful when coming from the machine with an authorized initiator name. 3. click Finish when you are done.

 

Distribute the virtual tape library to the backup server (the one-to-one correspondence between the memory card of the virtual tape library and the memory card of the Management Server) Assign virtual library to clients 1. select a client to assign. 2. click Finish when you are done. after completing the Configuration Wizard, If You Need To configuration Note: assign new virtual libraries, you can right-click on virtualtape library system and select Configuration Wizard or you can click on a virtual tape library or a client and select assign.

 

Assign virtual tape libraries to clients you can assign virtual tape libraries to clients in the following three ways: * use the Configuration Wizard-if you have already configured your system, you can launch the wizard by right-clicking on the virtualtape library system object in the console and selecting Configuration Wizard. * Right-click on a San client or on the everyone_fc or everyone_iscsi client and select assign. the everyone client is a generic client that you can assign to all (or some) of your virtual libraries/drives. * Right-click on a virtual tape library and select assign. after launching the wizard, follow these steps to continue: 1. assign virtual tape libraries/drives to your backup clients.

You can assign the entire library to a backup client or you can assign individual tape drives. This will treat each individually assigned tape drive as if it is a standalone tape drive.

2. click Finish when you are done. (FC version only) You shoshould perform a device scan on your backup server. the steps to do this vary according to the server's operating system. for Windows, control panel --> Computer Management --> Device Manager --> right-click on the device in the right pane --> scan for hardware changes.

4. Search for the virtual tape library on the backup server. If the database is successfully assigned, you can find the virtual tape library in Windows device management.
