DAT tape drive please refer to Installing an external DAT tape drive on page 29 Which rackmount systems can use HP StorageWorks DAT removable tape drives are used in conjunction with the HP Tape Array 5300 system which can be used with both full height and half height tape drives It will hold up to four HP StorageWorks DAT tape drives The tape array is designed to be installed into HP IBM and other compatible 19 rackmount systems It must be properly installed and configured Refer to your tape array documentation for further details Airflow requirements The HP Tape Array 5300 is designed to provide adequate airflow for up to four half height or up to two tull height tape drives As long as the tape array is fully populated it will provide adequate airtlow for your HP StorageWorks DAT tape drives If you have unused bays in the tape array you must install the blanking plates provided with the tape array This ensures that there is adequate airflow to the drives See the documentation with the tape array for details on installing blanking plates You should ensure that ventilation is adequate at the front and rear of the tape array How do connect the drive to my server The following guidelines apply e For optimum performance the drive should be the only device on the SCSI bus e If you daisy chain devices make sure that devices are of the same SCSI type and that each device on the same SCSI bus has a unique SCSI ID
9. Determine whether you need to change the SCSI ID from the default of 3 Why does the tape drive need a terminator Terminators are essential as they provide the correct voltages on the SCSI bus and prevent unwanted signal reflections from interfering with data transfers The rule is There must be termination at both physical ends of the bus and only at the ends Normally the HBA forms one end of the SCSI bus and provides termination You therefore need to ensure that the other end of the bus is terminated Attach the terminator to the appropriate SCSI OUT connector on the tape array Replacing the drive HP StorageWorks DAT removable drives can be removed and replaced without powering down the tape array However you should be aware of the following e Ifall drives in the tape array are powered up when the system is turned on the host will be aware of those drives You can remove any of those drives and replace it with another drive as long as there is no activity on the bus Do not remove or add drives to a bus that already has drives connected and running for example backing up or restoring data Wait until there is no activity on the bus before removing or adding drives e Ifa drive is not powered up or you place a drive in an empty slot after the system has been powered up the system will have to be reset before the host will recognize the drive e The SCSI IDs are controlled by the tape array not by the drives themselves so
10. HP One Button Disaster Recovery is a standard feature on all HP StorageWorks DAT tape drives However it can only be used with specific configurations and will only recover the server to which the tape drive is directly connected To check whether your system hardware operating system and backup software is OBDR compatible please refer to our World Wide Web site http www hp com go connect For more specific information concerning the benefits of OBDR and the latest new features please refer to our World Wide Web site http www hp com go obdr 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 e 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 e Hardware failures where the server is replaced by an identical component e File corruption because of an operating system error e File corruption because of an application software error e Viruses that prevent you from booting your system correctly e User err
