Figure 2 Split cable supplied with internal tape drives

Figure 3 Split cable supplied with external tape drives

CAUTION:

Use of the split cable may require some recabling of hard disk drive bays. Be aware that installation decisions require a clear understanding of your server’s current SAS conﬁguration, as s ummarized in

HowdoIconnectthedrivetomyserver?.

ffective way of connecting the tape drive to an HP ProLiant ser ver is to use the split cable

The simplest way of connecting a tape drive to your HP or non-HP SAS server is to purchase and install one of the supported HBAs. With external drives this allows you to connect to an external port on the HBA and greatly simpliﬁes the installation process, but you must also purchase an additional cable. See

ttp://www.hp.com/go/connect for supported HBAs and cabling options.

Figure 4 Cable for connection to an external SAS port (must be p urc ha s ed separately)

How do I connect the drive to my server?

If you are using the split cable supplied with the tape drive to connect to an HP ProLiant server, you must determine your server’s current SAS conﬁguration to decide which cabling option is appropriate.

• With some servers you can connect to a spare SAS connector on the SAS controller. This is a

straightforward installation and recommended. It is described as Option 1 in this guide.

• With servers that do not have a spare connector, you will need to recable hard disk drive bays,

using the supplied cable to replace an existing SAS cable. In a few instances, you may also lose

The cabling option for connecting to a newly-installed, dedicated HBA is described as Option 3 in this guide. See h

NOTE:

If you have a server with conventional parallel SCSI disk drives and controllers, you will need to purchase and install one of the supported HBAs; alternatively you may wish not to connect this unit and instead purchase an HP StorageWorks DAT SCSI or USB Tape Drive.

Option 2:

Connect to spare port, conn ection to host HBA supported and HBA has a spare SAS port

Do not modify the existing SAS conﬁguration. Use the split cable supplied with the tape drive to connect to the spare SAS port. See “Option 1: Connect cable to spare port on host SAS

controller”onpage25.

Replace existing SAS cable, connection to host HBA supported and HBA does not have a spare SAS port

Use the split cable supplied with the tape drive to replace the existing SAS cable and connect to the host SAS controller. See “Option 2: Connect cable to port on host SAS controller and

replace existing SAS cable” on page 27. Caution is advised for t his cabling option because

you may lose the use of one of your hard disk drive bays. If this is the case and the hard disk drive bay is required for use now or in the future, you must install a new HBA, option 3.

Option 3:

Non-HP servers

Option 3:

External drives

IMPORTANT:

Deciding which HBA and cabling conﬁguration to use with external drives is a complex choice and supported conﬁgurations are constantly being updated. Always refer to h for the latest information about cables and supported HBAs.

The supplied, split cable connects your tape drive to an internal port on your SAS controller. It is threaded through the rear panel of the server and requires a spare PCI slot to accommodate the SAS connector to the tape drive. The cable is attached to the host server’s i nternal SAS controller or an internal port on the SAS host bus adapter.

You cannot use the supplied cable to connect to an external SAS port. If you wish to connect to an external SAS port, you must purchase and install an additional HBA and an additional SAS c able and should ensure you have sufﬁcient, spare PCI slots to accommodate the HBA. If your server already has an active external port and you wish to connect to it, you must purchase a different cable.

Install new HBA, connec tion to host HBA not supported or hard disk drive bay occupied

Do not modify the existing SAS conﬁguration. Purchase an ad di tional HBA and use the split cable supplied with the tape drive to connect to an internal port on the new host HBA. See “Option 3: Connect to a new HBA (some HP ProLiant servers and all non-HP

servers)”onpage30.

2Driversandbackupsoftware

In this chapter:

•

“Install drivers ” on page 19

•

“Upgrade backup software” on page 20

Install drivers

Installing on Windows

One driver is required in order to use HP StorageWorks DAT SAS tape drives.

• hpdat: This is the tape driver that works with all HP DAT products. It is regularly updated and is

available on the HP StorageWorks CD-ROM or on the HP Support web site.

The CD contains a driver install package for the supported Microsoft Windows operating systems, see

ttp://www.hp.com/go/connect. If you prefer to use Windows Device Manager to install the tape

drivers manua lly, you will ﬁnd them in the drivers directory on the CD-ROM.

IMPORTANT:

We strongly recommend that you use the installer package on the HP StorageWorks CD-ROM to install the drivers BEFORE you connect the tape drive.

Updates to the drivers may be provided from time to time on the H P support web site

ttp://www.hp.com/support). We recommend that these are installed after using the installer on the

(h CD-ROM.

Recommended install process, before connecting the tape drive

1. Insert the HP StorageWorks Tape CD-ROM.

2. Select the install drivers link.

3. Run the automated installer and follow the process to load the onto the system.

4. Once you have installed the tape drive and rebooted, as described in this guide, the tape drive will

be detected automatically and the correct driver will be used.

Alternative install process, after connecting the tape drive

If you have not already installed drivers, the Windows Found New Hardware wizard may run when you power on the server and tape drive.

Either:

Follow the on-screen instructions to search for the required on the CD-ROM.

Or:

1. Cancel the wizard and insert the HP StorageWorks Tape CD-ROM.

2. Select the install drivers link on the CD-ROM.

3. Run the automated installer and follow the process to load the onto the system.

4. On completion of the installation the tape drive will be ready to use.

Upgrade backup software

It is important to check http:/ /www.hp.com/go/conn ect for software comp atibility and install a ny recommended up

NOTE:

Certain backup applications require you to use their own Tape driver instead of the HP Tape driver.

For o ptimum performance it is important to use a backup application that is appropriate for your system’s conﬁguration. In a direct attach conﬁguration, where the tape drive is attached to a standalone server, you can use backup software that is designed for a single server environment. In network conﬁgu rations you will need backup software that supports enterprise environments. HP, Symantec, Yosemite and Computer Associates all provide suitable products. Further details about these and other products that may be appropriate can be found on our connectivity web site.

1. Go to our connectivity web site: h

2. Select software compatibilit y .

3. Select your combination of operating system and tape drive m odel in the table. A list of supported

backup applications is displayed. This will also tell you whether your conﬁguration is compatible with HP One-Button Disaster Recovery, HP OBDR. (All HP StorageWorks DAT tape drives support HP OBDR. However, you can o nly use this feature if your system conﬁguration and backup application also support it. See “Using HP OBDR” on page 59.)

WARNING!

To avoid personal injury or damage to the server or tape drive, ensure that the server is disconnected from the mains power supply while you install the drive.

CAUTION:

Static electricity can damage electronic components. Always wear an antistatic wriststrap if one is available. If not, after you have disconnected power from the server and removed the cover, touch a bare metal part of the chassis. Similarly, touch a bare metal part of the drive before installing it.

1. Refer to your ser ver documentation for detailed instructions and assemble the necessar y tools and

materials.

2. Perform a normal system shutdown and turn off the server and any connected peripherals.

3. Remove the cover and access panel from the server, as detailed in your ser ver’s documentation.

As you work inside the server, you may have to disconnect other signal cables or power cables from other devices to maneuver the new drive into place. If you have to do this, make a note of their position and connections so you can put them back correctly later.

The internal tape drive may be installed in one of three conﬁgurations:

• Use the existing SAS c ontroller and connect the tape drive to a spare SAS port on the host

SAS c ontroller. This cabling option is suitable for some HP ProLiant servers only. It is described as Option 1 in this section.

• Use the existing SAS controller, but replace one of the existing SAS cables to the hard disk drive

bays. This requires some recabling inside the server, and may also disconnect one of the hard disk drive bays. This conﬁguration is suitable for some HP ProLiant servers only and, if it does disconnect a hard disk drive bay, you must be sure that the bay is not required for use. Do not move a hard disk to create an empty bay because you may damage your server conﬁguration. This cabling option is described as Option 2 in this section.

• Purchase and install an additional SAS HBA and connect the tape drive to the new HBA. This

NOTE:

You cannot use the supplied SAS cable to connect to an external SAS port. If you wish to con nect to an external SAS port, you must purchase and install an additional HBA that supports external connection and an additional cable. If your server already has an active external port and you wish to connect to it, you must purchase an additional cable.

Once you have installed the drive hardware, check that drivers have been installed correctly and you have the correct version of backup software, and verify that the tape drive is functioning properly before you store your valuable data.

1. Switch on the drive and the server.

2. Thetapedrivewillrunitshardwareself-test,whichtakesabout5seconds. Attheendofthe

hardware self-test:

• HP StorageWorks DAT 160 drives: If self-test passes, the green Ready L ED ﬂashes and then

shows steady green. If the test fails, the Drive Error and Tape Error LEDs ﬂash, while the Ready and Clean (or Use Cleaning Cartridge) LEDs are off. This continues until the drive is reset.

• All other drives: If self-test passes, both front panel lights should be off. If a hard error causes

the self-test to fail, the clean light changes to steady amber. See “Front panel” on page 51 for more information about front panel lights.

NOTE:

Certain backup applications require you to use their own Tape driver instead of the HP Tape driver.

3. Verify that the tape drive installation was successful.

For many operating systems you can run HP Library & Tape Tools from the HP StorageWorks CD-ROM. See also “Diagnostic Tools and Performance” on page 63 for more information about HP Library & Tape Tools, HP’s free diagnostics and troubleshooting software.

If you encounter a problem during this veriﬁcation procedure, turn to “Troubleshooting” on page 65 for help in diagnosing and ﬁxing the problem.

4. You are now ready to carry out a backup and restore test to check that the drive can write data

to tape. Use a blank cartridge. Windows Backup or native backup applications can be used to check basic tape drive operation, but they will not support all the advanced features of your tape drive. We recommend that you upgrade your software application before running this test. Check

If you want to protect the data on a cartridge from being altered or overwritten, you can write-protect the cartridge.

DAT SAS Tape Drives

Always remove the cartridge from the tape drive before you change the write protection.

• To write-protect a cartridge, slide the tab on the rear of the cartridge so that the recognition

hole is open.

• To write-enable a cartridge, slide the tab back so that the hole is closed.

Write-protection will not protect your cartridges against magnets (or bulk erasers).

Cleaning cartridges

HP recommends weekly cleaning of the tape drive using an HP cleaning car tridge. There are two types of cleaning cartridges; you must use a DAT 160 cleaning cartridge with DAT 160 tape drives, see

Table 6 on page 56.

If the cleaning cartridge is not ejected, it has probably expired. In this case, press the Eject button, discard the cleaning cartridge and repeat the operation with a new one.

2. Remove the cleaning cartridge from the drive.

The drive’s TapeAlert feature will send a message to your backup application when the tape heads need cleaning or a cleaning cartridge has expired.

Handling cartridges

• Do not attempt to clean the tape path or tape guides inside the cartridge.

• Do not leave cartridges in excessively dry or humid conditions.

• Do not leav

es to jam in the drive. Stick labels onto the label area o nly.

Getting the most out of cartridges and drives

• Use mostly the matching media type (DAT 160 media for HP StorageWorks DAT 160).

• Use media for the recommended number of times (DAT 160=100 full backups). Overuse of the

tape will cause it to degrade and possibly shed tape debris in the drive. Too many new tapes can also cause wear of the drive as they are rougher tha n used ones.

• Do not verify (DDS does read-after-write checking automatically).

• Do not overload the server during backups. Maximize the transfer rate (run overnight with no

other processes) and use incremental backups if convenient.

• Do not overuse your tape drive—it is designed for approximately three hours of tape pulling per

day, not constant usage—and clean the drive regularly. See “Cleaning cartridges”onpage56.

• If you want to bulk erase cartridges, this should be done in a controlled environment. You need to

make sure there are no other cartridges with sensitive information on them anywhere near the bulk eraser when in use. All data will be lost on cartridges that are b ulk erased.

y 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 replace 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.

Remote disaster recovery (ProLiant servers only)

The HP Remote I nsight Lights-Out Edition (RILOE) on ProLiant servers gives the IT Administrator the ability to completely recover a failed server at a remote location without physically traveling to where the

server resides. The on-site non-technical person need only insert the bootable cartridge into the tape drive when asked to do so by the administrator.

operating system to a state where it can run a normal data restore.

5. Once the operating system has been set up and rebooted, the Tape LED display on the tape drive

changes to constant green and you can remove the backup cartridge, if you wish. You are now ready to run a normal data restore. Follow the normal process for your restore application.

Optimizing performance

Various factors can affect tape drive performance, particularly in a network environment or if the drive is not on a dedicated bus.

If your tape drive is not performing as well as expected, consider the following points before contacting HP Support at h

• Have you installed the correct device drivers for your operating system and backup application?

See “Install drivers ” on page 19.

• Are you backing up across a network? The network load may be affecting the speed of transfer

or your backup application may only be appropriate for a single-server environment.

• Are you using the correct media for your model of tape drive? See

“Use the correct media”onpage55.

• Is the backup application writing buffers at the correct speed? You may need to tune the transfer,

buffer and block size settings to optimize the speed that the application writes data to the tape drive. HP StorageWorks DAT tape drives have an internal buffer of 8 MB.

3. Does an error appear during the boot sequence about a change to the RAID conﬁguration?

This error only appears if you have used the supplied cable to replace an existing SAS cable. Check the cabling between the disks and the SAS controller. If the problem persists, you have probably disconnected a hard disk drive bay that was in use. See “Option 2 for more

4. Has the system booted but the operating system has not seen the tape drive? Check that the

drive has power, the READY light should be illuminated. If it is not, check that the power cable is connected correctly to the tape drive. If READY is illuminated, check the cabling between the tape driveandtheSAScontroller.

DAT SAS Tape Drives

Clean the tape heads with the cleaning cartridge, see “Cleaning cartridges” on page 56. Be sure to use the correct cleaning cartridge.

• DAT 160 cleaning cartridges (C8015A) with DAT 160 tape drives.

• Standard cleaning car tridges (C5709A) with all other HP StorageWorks DAT tape drives

6. Try the operation again.

7. If the problem still occurs, try using a different cartridge.

8. If the problem is still there, the problem probably lies with the drive or the host computer.

Has the drive been moved recently? Have any cables been disconnected and reconnected? Has the environment changed—unusually hot, cold, damp or dr y? Has there been dust or dir t near the drive. Have reasonable precautions against static been taken?

The problem could lie with the drive:

1. Check the cables and connectors.

2. Clean the tape heads with the cleaning cartridge.

3. If the problem persists, check the environmental conditions against the speciﬁed limits (refer to

ttp://www.hp.com). Perhaps move the drive to a more suitable site.

Has a new operating system been installed in the host computer? Has new backup software been installed?

The problem could lie with the host or the software. Consult the computer’s operating manuals, the software manual, or seek help from a service engineer.

Problems with cartridges

If you experience any problems using HP branded cartridges, check:

If the cartridge is jammed or the backup application is unable to eject it, you can force eject the cartridge. Once the cartridge is successfully ejected, it is good practice to upgrade the ﬁrmware. If the failure occurs regularly, contact customer service at h

1. Either press and hold the Eject button on the front of the tape drive for a t least 15 seconds. Or press

the Eject button three times within 5 minutes.

2. Wait for the cartridge to be ejected. The drive waits until 35 seconds have passed from the tim e

of the ﬁrst press, to give the normal eject procedure a chance to proceed. After this period, it immediately releases the tape and ejects the cartridge, regardless of what operation it was performing. It is important that you allow sufﬁcienttimeforthedrivetocompletethisprocess.Ifyou interrupt it, you may damage the media or the tape drive. The drive is then reset as though you had turned the power off and then on again.

You may lose data if you force eject a cartridge. The tape may also become unreadable because an EOD (End of Data) mark may not be properly written.
