Introduction 1 Overview of Enterprise Backup Solutions Properly setting up a Fibre Channel storage area network (SAN) backup solution can be challenging. Typically components are purchased at different times and arrive separately or the components are purchased from different vendors. Each piece of hardware arrives with its own documentation for setup and deployment. These challenges may require additional time and money.
Introduction The configuration rules and recommendations are made based on the solution integration testing conducted by HP. Certain limitations apply and are noted where applicable. Solution Features The EBS with HP OpenView Storage Data Protector v5.1 integrates data protection and disaster recovery, ensuring recovery from any disruption.
Introduction Solution Components ■ Server(s) containing Fibre Channel Host Bus Adapter(s) ■ RAID Array Storage ■ Fibre Channel SAN Switch(es) ■ Router(s), such as the HP StorageWorks E2400-160 FC Interface Controller or the HP StorageWorks Network Storage Router E1200-160 ■ Tape Library, such as the MSL5000/6000 series or the ESL9000 series ■ Data protection software, such as HP OpenView Storage Data Protector v5.
Introduction Important Terms ■ Cell Manager—The Cell Manager is the main system in the cell. The Cell Manager: — Manages the cell from a central point — Contains the Internal Database (IDB) — Runs core Data Protector software — Runs Session Managers that start and stop backup and restore sessions and write session information to the IDB ■ Disk Agent—Install the Disk Agent on client systems you want to backup.
Introduction Manager-of-Managers Data Protector provides the Manager-of-Managers (MoM) for management of large environments with multiple cells. The MoM allows you to group multiple cells into a larger unit, which can be managed from a single point. New cells can be added, or existing cells can be split. MoM provides: ■ Centralized licensing repository—This optional feature enables simplified licensing management.
Introduction Note: The Device Auto Configuration Wizard is not available on all platforms, for example Sun Solaris. The wizard should be run from the Cell Manager. The wizard: ■ Performs device discovery on each client with the Media Agent installed ■ Adds robotic libraries and shared drives to the Data Protector Devices configuration ■ Configures Device Locking for shared drives Supported Configurations Figure 1 shows a diagram of a basic storage domain configuration.
Introduction Basic Storage Domain Configurations The basic EBS storage domain may consist of a heterogeneous connection of multiple servers sharing multiple libraries and RAID array storage systems.

Installation and Configuration 2 Before installing your backup software, refer to the HP StorageWorks EBS Design Guide for assistance in setting up your hardware.
Installation and Configuration Installing HP StorageWorks Storage Data Protector v5.1 After all components on the SAN are logged in and configured, the system is ready for the installation of Data Protector. Refer to the HP OpenView Storage Data Protector Installation and Licensing Guide or contact HP customer support for detailed installation procedures and requirements. Installing Data Protector Software HP recommends that you install in the following order: 1. Cell Manager 2. Installation Server 3.
Installation and Configuration 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.
Installation and Configuration ■ Use the Device Auto Configuration 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. ■ In Data Protector 5.
Installation and Configuration Note: If the setup wizard is unable to detect serial numbers of the robot or tape drives, which can happen when the drive or library firmware is upgraded, check via the library front panel to ensure the library reports a serial number for each device. Using the Data Protector Setup Wizard is recommended, however it is not available on all platforms, for example Sun Solaris.
Installation and Configuration Performance and Tuning To analyze speed and performance, it is necessary to examine the entire backup process as a system. Although many factors contribute to the overall performance of the system, there are four main factors that must be thoroughly understood to determine the maximum performance in any specific situation. These factors are: ■ Storage Connection—For the EBS, this is Fibre Channel connection.
Installation and Configuration Source Disk and File Systems In the past, tape performance was typically identified as a bottleneck. However, tape performance has now surpassed may of the source systems available today.
Installation and Configuration Tape Drive The tape drive is the fifth piece in determining backup and restore performance. HP tape drives have varying levels of performance. Factors such as file size (larger is better), directory depth, and data compressibility all affect system performance. Data interleaving during backup also affects restore performance. Use of the router and its connections to HP StorageWorks tape libraries is a simple way to scale backup performance.
Installation and Configuration PAT does not address tape solution issues such as whether HBA choices or system bus topology would adversely affect backup performance. PAT results will be a reflection of the system's performance as configured. This will be affected by various configuration details such as: ■ specific disk sub-systems attached ■ type of RAID configuration in use (i.e.

High Availability 3 For information on configuring HP-MC/ServiceGuard, Microsoft Cluster Server, and VERITAS Cluster Server for Solaris, refer to the Data Protector website at: http://h18006.www1.hp.com/products/storage/software/dataprotector/index.
High Availability Clustered EBS Configuration The EBS with Data Protector supports backup and restore of the primary and secondary nodes of a clustered pair of HP-UX MC/Service Guard and Microsoft Windows servers with failover. In the EBS environment, Tru64 and Sun Solaris are supported without failover.
Troubleshooting 4 This chapter lists issues and solutions for situations that can occur during installation, implementation, and administration of the HP StorageWorks Enterprise Backup Solution (EBS) with HP OpenView Storage Data Protector v5.1. Additionally, you can refer to the HP OpenView support website available at http://support.openview.hp.com Unable to execute wide SCSI commands Tape Library: Unable to execute wide SCSI commands.
Troubleshooting 2. Appendable Media—Media in “Good” condition, with some currently protected data objects, but the media is not full. The pool must be “appendable.” This media set is sorted according to the time of the last write. The most recently written medium is listed first. Order of use: when one or more media have protected objects, the most recently written media is reused first. 3.
Troubleshooting Error when configuring EADR or OBDR When attempting to configure Enhanced Automatic Disaster Recovery (EADR) or One Button Disaster Recovery (OBDR) on a Windows platform, the following message is displayed: Automatic DR information could not be collected. Aborting the collecting of system recovery data. The above issue has been seen if: 1. Device manager shows an incorrectly configured device: Check if all storage devices are configured correctly.
