Introduction Tape remains the most practical solution for removable storage, and it is often required by regulatory agencies to be archived and stored offsite. However, as the cost of commodity disk storage has decreased, many enterprises view disk-based backup solutions as a feasible alternative to tape-based backup.
deploy VTS to simplify and streamline traditional tape operations, reduce costs for storage hardware and tape media, automate backup and restore operations, and increase flexibility in managing backed-up data. The virtual environment The basic building blocks of VTS are vaults, pools, virtual tape drives, and virtual tapes. VTS can support multiple virtual tape drives that respond to tape commands just as a physical tape drive would.
Overview of features The heart of VTS is a middleware tape emulation engine that enables VTS to emulate tape storage to host servers and provides backup storage for the data on industry standard, lowcost disk arrays. Data stored in VTS can later be copied to real tape media for archival storage or disaster recovery if long-term backup copies are required.
Accessing the VTS web interface VTS is managed through a standard web browser interface. To access the web interface, launch a supported web browser that is on the same internal network as VTS, enter the following URL: https://hostname/ where hostname is the hostname of the VTS server. If VTS is configured to use a self-signed certificate to secure communication between your browser and the VTS web application server, the certificate may cause the browser to display a warning page and certificate errors.
Overview of Configuration Tasks After completing the procedures provided in the Virtual TapeServer Quick Start Guide, you can continue the initial configuration of the Virtual TapeServer (VTS) server. This guide provides those configuration procedures. Note If you are upgrading to 6.04.04, refer to the Virtual TapeServer Release Notes for upgrade instructions and considerations before completing the server configuration outlined here.
6 | Overview of Configuration Tasks
Reconfiguring Vaults By default, vault storage is configured on the Virtual TapeServer (VTS) server. Prior to using this storage, you may want to review and change the configuration. For example, you may want to define additional vaults, which provide a convenient way to separate data for different applications or users. You may want to reconfigure vault storage before creating virtual tape drives (VTDs) or using VTS, though you can use VTS without reconfiguring vaults.
Here is an example of the output. The bolded lines indicate partitions that are eligible for configuration: Filesystem /dev/cciss/c0d0p2 /dev/cciss/c0d0p4 /dev/cciss/c0d0p1 tmpfs /dev/cciss/c0d1p1 Size 19G 112G 99M 502M 3.3T Used 6.7G 338M 24M 0 535G Avail 12G 106G 70M 502M 2.6T Use% Mounted on 38% / 1% /VAULT00 26% /boot 0% /dev/shm 17% /VAULT01 3. Use parted to display the current partition layout for all disks.
c. Delete any partitions that you want to reconfigure by entering the following command: d d. Select the partition by entering the following command: 1 e. Add a new partition by entering the following command: n f. Choose the primary partition by entering the following command: p g. Select the first partition by entering the following command: 1 h. Accept the cylinder defaults by pressing ENTER twice. i.
f. Review the layout by entering the following command: print Here is an example of the output: Model: Compaq Smart Array (cpqarray) Disk /dev/cciss/c0d3: 2500GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number 1 2 Start 17.4kB 1250GB End 1250GB 2500GB Size 1250GB 1250GB File system ext3 primary Name primary Flags g. Quit parted. quit 4. Create file systems on the newly created partitions.
Configuring Ports and Licensing To complete configuration, you must configure ports and licensing. This chapter describes these procedures. Configuring ports After cabling the host server(s) and external devices to the VTS server, you must configure the ports to enable VTS to communicate properly with each device (target or initiator). Or, if you attach a physical tape drive or storage device to the server after initial configuration, you must define the port as physical.
3. Click Manage Connections on the navigation pane. Ports are configured in the MANAGE PORT CONFIGURATION section of the page. (An image of your server will be displayed. The example below is an image of the DL380 G6.) 4. Configure each port as described in the help. To view the help, click the Help button at the top of the page. Configuring licensing Before you can use Virtual TapeServer (VTS), you must enable licensing.
Requires Administration group membership To enter a license key 1. Log in to the VTS web interface using an account that is a member of the Administration group. Click the Log In button at the top of the page and enter a username and password. 2. Click Supervisor Functions on the navigation pane. 3. Click Manage System Licenses. The following page is displayed: 4. Enter license keys as described in the help. To view the help, click the Help button at the top of the page. 5. Restart the TapeServer service.
14 | Configuring Ports and Licensing
Creating Virtual Tape Drives After Virtual TapeServer (VTS) is deployed, you must create virtual tape drives (VTDs). Up to 32 VTDs are supported per VTS server, Your licensing determines how many VTDs you can create. If you must modify a VTD after it is created, refer to the online help. Creating a standalone VTD The following table describes the properties that you must set when defining a standalone VTD.
The following procedure describes how to create a VTD using the Manage Connections page. The full procedure is documented in the online help, which is accessed by clicking the Help button on the Manage Connections page of the VTS web interface. Note At least one port must be set to Virtual (target) mode on the Manage Connections page before you can create a VTD. Ports should have been configured as described in the help. Requires the View/Manage Configuration access right To add a VTD 1.
4. Click Add Virtual Tape Drive in the VIRTUAL TAPE DRIVES section of the Manage Connections page. The following is displayed: 5. Configure the VTD as described in the help. To view the help, click the Help button at the top of the page. You can now create virtual tapes for use with VTDs. And, it is recommended that you back up the VTS database after modifying the VTS configuration. Refer to the Virtual TapeServer Operations and Administration Guide for these procedures.
6. If steps 4 and 5 are successful, issue the SCF command to add a tape. Here is an example: SCF ADD TAPE $VFHP00, SENDTO STORAGE, CLIM S1002531, LUN 1, PRIMARYCPU 2,BACKUPCPU 2. 7. Start the virtual tape drive. If a 224 error occurs, delete the drive and make sure steps 4 and 5 are successful. Validating access to VTDs from the NonStop server To validate that the NonStop server can back up to configured VTDs in VTS, you must configure the NonStop server to add the VTD.
To start the virtual tape drive, enter the following command on the NonStop server: SCF START TAPE $VTD This command should return messages similar to the following if successful: SCF - T9082G02 - (06JAN06) (31OCT05) - 01/19/2007 08:42:11 System \DEV3 (C) 1986 Tandem (C) 2006 Hewlett Packard Development Company, L.P.
