It goes into a special disaster recovery mode that enables it to restore your operating system and reboot. It acts like a bootable CD-ROM. (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.) 2. It returns to normal tape drive mode and restores the data. DAT SAS Tape Drives 71

If your system does not support HP One-Button Disaster Recovery, you can still use your tape drive
normally 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.
What does HP OBDR do?
Using just the tape drive and the most recent backup cartridge HP OBDR allows you to recover from
the following types of system disaster:
•
Hard disk failures, as long as the replacement hard disk is the same size or larger than the original
and uses the same interface (for example, replace a SCSI hard disk with another SCSI disk or re-
place a SAS hard disk with another SAS disk)
•
Hardware failures where the server is replaced by an identical component
•
File corruption because of an operating system error
•
File corruption because of an application software error
•
Viruses that prevent you from booting your system correctly
•
User errors that stop you from booting your system correctly
When you run HP One-Button Disaster Recovery, your tape drive goes through the following sequence:
1.
It goes into a special disaster recovery mode that enables it to restore your operating system and
reboot. It acts like a bootable CD-ROM. (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.)
2.
It returns to normal tape drive mode and restores the data.
