One button disaster recovery (OBDR) The principle behind OBDR is simple. The tape drive is used to perform full system backups in the normal way. However, additional Disaster Recovery information is automatically written to the tape at the same time. Using a patented process, the tape drive is able to emulate a CD- ROM drive so that during a Disaster Recovery the computer can boot from this drive. Once the boot process has completed, the tape drive switches back into normal mode and proceeds with restoring data. IMPORTANT: Your system s ability to boot from CD-ROM is normally enabled by default. If you have changed this setting, you will need to enable it again. Refer to your system BIOS manual for further details. The reliability of a Disaster Recovery strategy depends on the frequency and skill with which it is done. Because OBDR backups are quick and simple to perform, they are more likely to be done on a regular basis. In addition, the simplicity of the backup process leaves very little scope for user error and allows even the non-technical to backup and restore a complex system. Requirements HP tape drive and server support HP StorageWorks One-Button Disaster Recovery (OBDR) for ProLiant servers is a feature on HP DAT and Ultrium tape drives and HP DAT autoloaders. To check whether your ProLiant system (hardware, operating system and backup software) is OBDR compatible, please refer to our World Wide Web site www.hp.com/go/connect. If your server does not support OBDR, you can still use your HP tape device to back up and restore data. However, you must remember to create a separate set of emergency recovery disks for your operating system whenever you change your system configuration. For more specific information concerning the benefits of OBDR and the latest new features please refer to our World Wide Web site www.hp.com/go/obdr. Data Protector Express (DPX) DPX Standard Edition is available at www.hp.com/go/dataprotectorexpress DPX Single Server Edition ships free with all HP DAT and Ultrium tape drives and DAT autoloaders Both editions have a free evaluation period of 60 days A permanent license key can be obtained after registering DPX at no cost Creating the OBDR tape using Data Protector Express Before an OBDR recovery can be made an OBDR tape must be created. The procedure for creating an OBDR tape using Data Protector Express is simple. Once DPX is installed, every full backup with overwrite that is performed will create an OBDR disaster recovery tape. No additional work is required. 1. Log into the DPX Domain
2. Select the server you want to create the OBDR tape from 3. Select Devices 4. Select the tape drive you want to create the OBDR tape with
5. Select the Backup wizard 6. Select Backup Local Machine Backup Local Machine Wizard appears
7. Enter a backup description, Click Next Device Options appears 8. Verify that the Backup mode is Full and the Write mode is Overwrite all media 9. Click Next
10. Schedule the backup job 11. To verify that the OBDR tape is being created, click on Status IMPORTANT: Once the OBDR tape has been created, it should be stored in a safe and secure location in case it is needed to restore your ProLiant server.
Performing an OBDR restore Local mode 1. Insert the OBDR tape media into the HP tape drive or DAT autoloader 2. Place the HP tape drive or DAT autoloader into OBDR mode using one of the following methods: Hold the eject button and power cycle the ProLiant server if the tape device is internally connected Hold the eject button and power cycle the tape device if it is externally connected to your ProLiant server The DAT 72x10 autoloader does not have an eject button. You must either use F8 at POST or use the OCP (Operational Control Panel) on the front of the autoloader to invoke OBDR on the tape drive. See the F8 descriptions below for more details. The tape device will then bootup in OBDR mode and the restore process will start, see step 3 below. 3. From the Available Options menu, select Recover Entire System, then press F10 to continue
4.. Verify choice to recover the entire system, then press F10 to continue You will receive one final warning before the restore process begins. Press F10 to start the recovery process
The DPX Wizard will automatically begin to restore your operating system, application files and data files. If you have more than one tape media, you will be prompted when to insert the additional media. After DPX finishes restoring the data, a reboot is required and the ProLiant server has now been restored. Remote mode IMPORTANT: To perform this function remotely requires the HP Integrated Lights-Out (ilo) or Remote Insight Lights Out Edition (RILOE) board 1. Insert the OBDR tape media into the HP tape drive or DAT autoloader at remote location 2. Power cycle the server and press the <F8> function key at POST (See the F8 descriptions below for more details) F8 descriptions There are several F8 prompts during POST of a ProLiant Server. In order to know which F8 prompt to select, see the following descriptions. DAT USB Tape Drives DAT USB tape drive connected to a ProLiant server will have the following F8 prompt at POST:
1. After pressing F8 the following menu will appear, press 1 to enable OBDR mode. SCSI or SAS Tape Drives PCI-based HBA SCSI or SAS tape drives connected to a ProLiant server via a PCI-based HBA will have the following F8 prompt at POST: 1. After pressing F8 the following menu will appear, press 1 to enable OBDR mode.
SCSI or SAS Tape Drives Smart Array Controller SCSI or SAS tape drives connected to a ProLiant server via a Smart Array Controller (embedded or PCI-based controller) will require pressing F8 at the following prompt to run the Option ROM Configuration for Arrays Utility (ORCA) at POST: 1. Select Configure OBDR from the ORCA Main Menu:
2. Select the tape drive to put into OBDR mode. 3. Press F8 again to put the drive into OBDR mode.
