Info

The Cell Manager and Installation Servers are installed directly from the CD or from the software package located on the server hard drive. After you have installed the Cell Manager and Installation Servers you can then install the components on various client systems using the Data Protector Installation GUI. There are certain hardware and software requirements that need to be met by Installation Servers and Cell Managers before you start installing the software. A dedicated port, generally port 5555, needs to be available throughout the cell. Different Linux distributions often reserve port 5555 for another device. Check /etc/services for assigned ports on Linux servers. See the HP OpenView Storage Data Protector Installation and Licensing Guide for details. Installation best practices • Follow the HP StorageWorks EBS Compatibility Matrix and the HP StorageWorks Enterprise Backup Solution Design Guide. • The matrix of hardware, software, and firmware is updated monthly and helps customers and support personnel maintain their EBS environment. It is not necessary to immediately update an environment to the latest revision on the matrix. However, you should be aware of updates and changes if you experience any problems that may be related to newer or older software, driver, or firmware versions. • The design guide describes currently supported EBS hardware configurations and how to efficiently and effectively provide shared tape library backup in a heterogeneous SAN environment. • Do not create cells with multiple time zones. Each cell should be within one time zone. • Limit rebooting during backup windows. • Rebooting hosts in an EBS environment during backup windows can cause job failures and configuration errors. • When rebooting is necessary, verify the configuration of the host when maintenance or reboot is complete. • Use the DNS Connection Check tool to verify if: • The Cell Manager properly resolves every other client of the cell • Every client of the cell properly resolves the Cell Manager • Every system, on which the Media Agent was installed, resolves every other client • Each system resolves every other system accommodating a Media Agent • Be sure the latest Data Protector and operating system patches have been installed. • Make sure that each media server scanned with the Autoconfiguration Wizard sees and has configured all required tape devices. On UNIX systems, make sure that a device file has been created or assigned. On Windows systems that are running the Storport HBA driver, install the tape device drivers. On Windows systems that are not running the Storport HBA driver, it is recommended that tape device drivers are not installed. • Use the Device Autoconfiguration Wizard for all supported platforms. This wizard coordinates device configuration among all the hosts in a shared storage environment. It is essential that all hosts be configured properly with the appropriate device name, index, robot drive number, media, drive type, and device locking. Import the additional hostnames for multiple LAN interfaces In Data Protector, there exists the ability to import the additional hostnames for multiple LAN interfaces using the Virtual Host feature in the GUI. For most customers it is much easier to import the additional hostname from the GUI (and less error-prone), than to type in complicated omnirc file entries. To use this feature, first configure the client host that matches the hostname of the system. For the Cell Manager, it should be installed first using its primary hostname. Next, import the additional hosts as follows: 1. From the Data Protector GUI (Manager.exe): Select Clients context, then right-click Clients and select Import Client. Type in the hostname assigned to additional LAN interface. Select Virtual Host, then Finish. 18 Installation and configuration
2. Configure correct hostnames in logical device settings to use alternate LAN interfaces for Media Agents (see the HP OpenView Storage Data Protector Administrator's Guide for details). 3. Configure correct hostnames in backup specifications to use alternate LAN interface for Disk Agents (see the HP OpenView Storage Data Protector Administrator's Guide for details). Device serialization The Data Protector setup wizard uses device serialization, a firmware feature that allows device identification and configuration. Each robot and drive found in the configuration returns a unique serial number. For any robots in the configuration, an additional command is issued to the robot. The robot returns the number of drives and the serial number for each of the drives contained in the robot. This information is used by the wizard to determine the correct drive index for each drive in the robot. NOTE: Use of the Data Protector Device Autoconfiguration Wizard is recommended, but it is also possible to configure devices manually. Default device attributes may be changed after using either configuration method. Backup specifications Patching Data Protector has a wizard that allows the administrator to specify a backup source, destination, options, and schedule. Configuring a backup consists of the following steps: 1. Selecting what to back up—the data sources on the Disk Agent clients 2. Selecting where to back up to—the backup devices connected to the Media Agent clients 3. Selecting how to back up—backup options 4. Optionally, you can schedule an unattended backup Before setting the backup specifications, consider the following: • You need to have a Disk Agent installed on every system that is to be backed up, unless you use NFS (on UNIX) or Network Share Backup (on Windows) for backing up these systems. • You need to have at least one backup device configured in the Data Protector cell. • You need to have media prepared for your backup. NOTE: Before use, tape media must be formatted. If tapes are formatted, write attributes are changed (such as block size or segment size), and it is necessary to reformat the media to accept the new attribute settings. • You need to have appropriate user rights for performing a backup. See the HP OpenView Storage Data Protector Administrator’s Guide for complete instructions on configuring backup specifications. Data Protector provides a convenient patching mechanism that enables push upgrades from the Data Protector GUI. Unless a special circumstance exists, patches are typically installed on the Cell Server, and then pushed out to the clients. See the accompanying documentation for the individual patch that is being installed for specific instructions on its installation. Patches can be downloaded from the http://www.hp.com/go/dataprotector web site. Enterprise Backup Solution with HP Data Protector implementation guide 19
