About this guide
1 Before you start In • • • • • • this chapter: “Overview” on page 15 “Optional tape attach one” on page 15 “Software and hardware requirements” on page 16 “Terminology” on page 16 “Storage capacity” on page 19 “Compression” on page 21 Overview The HP StorageWorks D2D Backup System is an iSCSI disk-based storage appliance that emulates up to six tape devices; these tape devices can be used to back up a maximum of six host network servers or PCs.
To find out which Ultrium Tape Drive models and HBAs and are supported, refer to www.hp.com/go/connect . Software and hardware requirements Refer to www.hp.com/go/connect for the latest connectivity and compatibility information. • The HP D2D Backup System should be connected to a Gigabit Ethernet network. 100 Base-T Ethernet will limit performance; 10 Base-T Ethernet will severely limit performance. For example network topologies, see “Supported network configurations” on page 24.
• Multiple servers may not back up to a single tape device. Figure 2 on page 17 shows a configuration with a single host. Figure 3 on page 18 shows a configuration with six hosts. See “Connecting and installing the HP D2D Backup System” on page 23 for more example configurations. Host1 Host2 Host3 Host4/5/6 LAN 1 2 3 4 5 6 7 8 Autoloader 1 HP StorageWorks D2D Backup System 1.

The HP D2D Backup System can be used to back up a maximum of six hosts 2. The Installation wizard automatically generates an autoloader for each host. The user may specify the number of slots during installation.
Physical tape drives A physical tape drive is a tape drive that is attached to the HP D2D Backup System or the host computer, so that data can be moved from the HP D2D Backup System and stored offsite. (It should not be confused with the tape drive device that can be configured as one of the backup devices on the HP D2D Backup System.
that you actually require. If you configure six 24-slot autoloaders, you should be aware that you have committed 192 GB of disk space. Only do this, if you are sure all slots will be used. Once added, slots cannot be removed. 8 7 6 5 8 7 6 5 4 3 2 1 4 3 2 1 1. 8 x 2 GB of physical disk space has been committed. 2. The remainder of the configured maximum capacity is used only as needed, but the initial 2 GB is permanently committed.
Compression The HP D2D Backup System does not apply hardware compression to backed-up data, but if you are moving data from the HP D2D to physical tape, bear in mind that HP StorageWorks tape drives do apply compression. Therefore, 200 GB of data on the HP D2D Backup System will require less space on a physical tape cartridge. If moving data to a physical cartridge for offsite storage, there is no need for concern if the data seems to utilize less space.

2 Connecting and installing the HP D2D Backup System In • • • • this chapter: “Connect the hardware” on page 23 “Supported network configurations” on page 24 “Software installation, discovery and configuration” on page 26 “Web browser settings” on page 26 Connect the hardware 1. Network connector 2. Power connector Figure 5 Network and power connectors 1. Always use the supplied power cord to connect the HP D2D Backup System to the main power supply.
DHCP and static IP addressing DHCP network addressing is enabled by default, which means that an IP address and other network settings are assigned automatically when you connect the HP D2D Backup System to a network that has a DHCP server. If preferred, you can use static IP addressing and assign settings manually during the installation process. In both instances, the HP D2D Backup System should be on the same logical and physical network as the host machine connecting to it.
PC Server Server Switch Supplied cable LAN HP StorageWorks D2D Backup System Figure 7 Connecting to a business server on the main network In some environments, backup data is kept separate from day-to-day office network traffic, as illustrated in Figure 8 on page 25. There is a separate, dedicated IP network for all hosts that need data to be backed up.
This ensures good backup performance. However, only the backup server can be backed up; other devices on the network must be configured as clients that back up to the designated backup server over the business network, which may impact performance.

1. 2. 3. 4. 5. 6. If you have already powered up the HP D2D Backup System, power it down and disconnect the cables before you start. Remove the access panel from the HP D2D Backup System. Install the HBA. Install an internal tape drive and connect it to the HBA (if required). Replace the access panel on the HP D2D Backup System. Connect an external tape drive (if required).
Figure 12 Removing the front bezel Installing the HBA 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. The supported PCI-Express HBA should be installed in the top PCI slot. Please refer to www.hp.
Figure 14 Removing the top expansion slot cover IMPORTANT: It may be necessary to temporarily remove the slot cover next to the slot in which you are installing the HBA. 3. Install the new HBA in the top slot. Figure 15 Installing the HBA 4. Reinstall the slot cover retainer (1) and secure it with the screw that you removed earlier (2).
Figure 16 Replacing the PCI slot cover Installing an internal tape drive Read this section if your are installing an internal tape drive. If you are connecting an external tape drive, go to “Replacing the access panel and bezel” on page 35. 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.
CAUTION: The Ultrium half-height tape drive allows only 3 mm engagement of the screw into the tape drive. To avoid damage to the tape drive, it is important to use the correct screws, which have a slightly thicker head than general mounting screws, and the metal shims. The shims prevent overtightening of the screws which may cause the drive mounts to sheer. Figure 18 Selecting the correct screws 3. Attach the screws and shims to the tape drive as illustrated (1).

4 The Installation wizard This chapter is relevant for users installing on a Windows host. If you are installing on a Linux system, please refer to the “Linux Configuration Guide” on the HP StorageWorks Tape CD-ROM.
1. LEDs 2. Power On button Figure 25 Powering on the HP D2D Backup System Run the Installation wizard The HP D2D Backup System can be used to back up a maximum of six hosts. You should run the Installation wizard on each host that will provide a source of data for backup. The host may be a server, workstation or PC. 1. Insert the CD-ROM supplied with your HP D2D Backup System into the host machine. It should launch automatically. If it does not, locate the D2DInstallationWizard.
• Discovery: This will allow you to locate your HP D2D Backup System on the network and configure network settings. If you have multiple devices on your network, a list is displayed so that you can select the required HP D2D Backup System. The configuration page for the device is displayed. DHCP is enabled by default. If you wish to use static IP addressing, disable DHCP and enter the IP address details.
TIP: If more than one HP D2D Backup System is being configured at the same time, it may be useful to physically identify a D2D device. Use Beacon mode to flash the LEDs on the selected device. • iSCSI installation and configuration: If required, this step retrieves and installs the Microsoft iSCSI initiator, connects this host to the HP D2D Backup System and configures an autoloader, as defined by the user.
Figure 26 Creating the backup device 3. The Installation wizard sets up a link to the Web Management Interface on the host’s desktop and gives you the option of launching it. Once it has been assigned network settings, the HP D2D Backup System is ready to use. See “The Web Management Interface ” on page 63. The HP D2D Backup System does not appear as a device under My Computer and it is not mapped to a drive letter (although it can be seen as a tape drive (1) and medium changer (2) from Device Manager).
The Installation wizard
5 Advanced installation Although the Installation wizard is the recommended way to install the HP D2D Backup System, it is possible to install it manually. You may also need to run phases independently when troubleshooting.
Beacon mode The HP D2D Backup System supports a Beacon LED sequence, which helps a user identify which unit is being configured, if several are connected to the network. See also “LEDs ” on page 53. If the HP D2D Backup System is new and not yet configured When installing the HP D2D Backup System for the first time, this step must be completed successfully before you can connect from your host.
on each host. If the host does not have the Microsoft iSCSI initiator, it will not be able to connect to the autoloader (or tape drive) configured on HP D2D Backup System and will not be able to perform backups. The Microsoft iSCSI initiator must be retrieved from the Microsoft website. Figure 27 iSCSI Initiator download page 1, amd 64 Use with amd ® 64-bit processors and with Intel ® em64t processors, when running a 64-bit version of the Windows operating system.
General tab You do not normally need to make any changes on the General tab. The Initiator Node Name is generated automatically, which guarantees that it will be unique on your network. The other fields relate to authentication and are not needed for the HP D2D Backup System. Only use them if required to by your IT policy. (If you use Secret to enter an encryption string in this dialog to authenticate targets, you must also enter the same string on the Web Management interface in the iSCSI page.
• If this is the first time that the iSCSI Initiator has been configured and the Installation wizard has not been run, it will automatically create an 8-slot autoloader with two target devices (loader and tape drive). • If target devices have already been configured for the host in the past, they appear in the list; no more are created. Targets tab This tab contains a list of all available devices. When you run the iSCSI Initiator manually, new devices have a status of Inactive.
We recommend that you also select the Automatically restore this connection when the system boots option in the Log On dialog. Persistent Targets tab The Persistent Targets tab shows the targets that have been configured to restore automatically on reboot. During initial configuration, it is for information only. However, if you want to stop the host automatically connecting to a device, you must select the device on this tab and Remove it.
Bound Volumes/Devices tab No configuration is required on the Bound Volumes/Devices tab. Linux iSCSI initiator An iSCSI initiator is embedded in the operating system. Please refer to the “Linux Configuration Guide” on the HP StorageWorks Tape CD-ROM for instructions on using it. Make sure that you have downloaded the latest operating system patches before you configure your system. Manual driver installation Two drivers are required; an HP LTO Tape driver and a medium changer driver.
HP LTO Tape driver The HP LTO Tape driver must be installed to allow your system to recognize the Ultrium devices created by the HP D2D Backup System. Tape drivers can be installed from the drivers directory on the HP StorageWorks CD-ROM, where they are supplied as an installer application and as driver files for manual installation. Also check the HP website for driver updates at www.hp.com/support. The tape drive is reported to your backup application (and Windows Device Manager) as an LTO-3 device.
6 LEDs In this chapter: • “Understanding the LEDs” on page 53 • “Beacon mode” on page 53 Understanding the LEDs Figure 28 LEDs 1 Disk Activity Flashing Green = Disk activity in progress. 2 Disk Status Solid Green = All disks are working correctly. Flashing Orange = A disk has failed. 3 Disk Capacity Solid Green = Normal operation and disk space is available. Solid Orange = Disk threshold capacity exceeded, device is nearly full. Status Solid Green = System is booted and operating normally.
Use the Network page of the Web Management Interface to turn Beacon Mode on and off. This flashes the LEDs on the selected device. If you do not switch off Beacon Mode from the Network page, it will continue for 5 minutes.
7 Backup scenarios using the HP D2D Backup System The HP D2D Backup System combines all the traditional benefits of tape technology, such as support for complex media rotation schemes, with the rapid backup and restore time that is only possible from disk. Backup applications allow users to configure rotation schemes that use tapes for specific days, weeks and months of a year, often applying different retention policies to each backup job. Such rotation schemes require an autoloader as the backup device.

NOTE: The web browser used to communicate with the D2D Backup System must have Active Scripting or JAVA scripting enabled. If it does not, some of the browser buttons may not be displayed. See “Web browser settings” on page 26. Summary (Home) Whenever you log in, the Summary page is displayed. Use this page: • To display information about your HP D2D Backup System and the backup devices that have been configured for it. • To monitor system health and status.
Table 2 Summary page layout 1 Navigation bar Select the appropriate option from the side bar. 2 Help and logout The Help option opens the help pages. Logout closes your session on the HP D2D Backup System. If somebody else logs in, you will be automatically logged out. 3 Device information This section provides the information that identifies your HP D2D Backup System. It shows the IP Address and Network Name of the HP D2D Backup System.
To edit device details 1. Click on Select to view the details for the required device and then click on Edit. 2. Amend details as appropriate and click Update to apply them. See “Device parameters” on page 67 To create a new device 1. To create a new device, select the appropriate device type (Autoloader or Tape Drive) from the drop-down menu and click on Create to create a new device for the host. 2. Enter the appropriate details and click Create.
Table 3 Device parameters Autoloader Name or Tape Drive Name: This is the name that is used to identify that device (autoloader or tape drive). You may like to enter a name that identifies the host or backup job with which it is associated. Total No of Cartridge Slots: This is where you define the number of slots that you require for your tape rotation strategy. For autoloaders you can select a number between 8 and 24 from the pull-down menu; each slot will initially be assigned a 200 GB cartridge.
The Web Management Interface
Table 4 Cartridge parameters Location The Location column identifies each element of the autoloader that is available to hold a cartridge. There are three elements: • Slot n: which is one of the standard autoloader slots • Mail slot: which is a dedicated slot that is used to hold a cartridge that is ready for exporting to or importing from physical tape. Cartridges can only be moved into the mail slot by the backup application on the host machine.
To write protect a cartridge Click Edit for the appropriate cartridge. Check the Write Protected check box for the cartridge. Your backup application will not be able to write any more data to it. To edit maximum size The only time you can resize cartridges is when you first create an autoloader or add slots and they are blank. Once the cartridges are made available to the backup application, it formats them ready for use and they are no longer blank, even if you have not yet written data to them.
• If you use the Create button on an empty slot, the backup application needs to inventory it (add it to its database or catalog) before it can access it. • If you use the Create button on an empty mail slot, you can use the backup application to move the blank, new cartridge to an empty cartridge slot, without having to run an inventory. This saves some processing time.
Network configuration The details in this section reflect the IP settings that were specified during installation. The HP D2D Backup System supports DHCP and this is turned on by default. You may need to edit the details if there is a conflict in the IP address, or you move the host to a different network node. Be aware that any changes you make to the network settings could affect how you connect again to the HP D2D Backup System.
Table 5 Network parameters Network Name: This is the name of the HP D2D Backup System. You can use the network name, instead of the IP address, to log on to the Web Management Interface. DHCP: Check or uncheck the box to enable or disable this feature. If DHCP is turned off, you must manually specify all the network settings for the HP D2D Backup System. If DHCP is turned on, the majority of the network settings are obtained automatically. However, even when DHCP is on the Network Name must be specified.
Email Alerts (Configuration) This page is used to set up details of the email servers that will be used to route messages about the HP D2D Backup System and to specify up to four email recipients. Messages are generated if a disk fails or reaches its threshold capacity, if the system reboots, if there are network problems or if there is a critical hardware failure.
Table 6 Email parameters SMTP Server: This is the IP address of the email server. Username and Password: Some email servers require authentication to send email alerts. If required, enter a Username and a Password here that are valid on the SMTP server entered in the previous box. Sender’s Email Account: This is the email account to which the email will be attributed in the recipient’s inbox. The account must exist on the email server.
• Anonymous Authentication (anyone can log on, you do not need to provide a Username and Password when you configure email alerts) • Basic Authentication, where a user name and password are required and should be provided when you configure email alerts NOTE: Integrated Windows Authentication is not supported with the HP D2D Backup System.
The red area indicates the threshold capacity. The system will send warning messages to email recipients that the disks are reaching capacity. The Disk Usage icon on the Summary page will also indicate that disk space is running out and the Disk Capacity LED will flash. You cannot add physical disk space, but you may be able to create some space. Options for creating space, if the disks start to get full, include: • Review your backup jobs to see if you can reduce the size of backup or retention time.
Log (Status) This page presents a time and date stamped list of significant system events. The most recent information is shown at the top of the list. The icons identify whether the messages are information, error or warning messages. The Log is maintained even if the HP D2D Backup System is power cycled. Use the Clear Log button to clear the log.
Tape Attach pages These pages allow you to manage copy, export and import activities between the HP D2D Backup System and an attached tape drive. They are described in detail in “Export, import and copy to an attached tape drive” on page 83. Shutdown (Admin) This option allows you to shut down the HP D2D Backup System cleanly. It is the only recommended way of powering off the device. If you remove the power in any other way and a host is carrying out a backup or restore, you may lose or corrupt data.
WARNING! Before shutting down always ensure that there are no backup or restore jobs in progress and that no future jobs are scheduled to start whilst the system is shut down. If hosts do not automatically reconnect to the HP D2D Backup System when it restarts, you must reconnect manually from the iSCSI Initiator on each host, see “Targets tab” on page 49.

Check www.hp.com/support for the latest firmware and download it to your hard disk. 2. Select Firmware from the Web Management Interface and click Upgrade. 3. Make sure that there are no backup or restore jobs in progress and that no future jobs are scheduled to start whilst the firmware is upgrading. Click Yes. 4. Click Browse...
WARNING! Once you have started to upgrade the firmware, it is important that you allow it to complete. Do not attempt to cancel the upgrade process, or power off the machine. NOTE: The tape drive is reported to your backup application (and Windows Device Manager) as an LTO-3 device. This is the default behavior of the tape drive and there is no need and no way to change it on the HP D2D Backup System. In earlier versions of the HP D2D Backup System firmware, the tape drive was reported as an LTO-2 device.
9 Export, import and copy using an attached tape drive If your organization’s backup strategy also requires the ability to archive backed-up data for offsite storage, there are two ways of achieving this: • Attach an HP Ultrium tape drive directly to the HP D2D Backup System and use the copy, export and import facilities in the Web Management Interface to transfer data manually or to schedule jobs. • Attach a supported tape drive to a host machine on the storage network.
• Import refers to the process that returns the cartridge from the attached tape drive to the HP D2D Backup System. • Copy refers to the process that creates an additional copy of the cartridge on the physical tape drive. Backup applications may use similar terminology to describe the processes for transferring data to a slot where it can be exported to a backup device and for restoring it to the application’s database or catalog after loss or failure. Please refer to the white papers on http://www.hp.
Step 1 Use backup application on host to write to cartridge. Step 2 Use HP D2D Web Management Interface to copy to tape drive.

Copy creates two instances of the same cartridge; one stored on the HP D2D, the other on physical tape.
device for use with restores at a later date. If a restore is urgently required, the administrator can put the copied cartridge into a physical tape drive attached to the host and restore directly from that. In either case, the backup application is aware of the cartridge’s existence. • Both the D2D system and the host are lost.
Step 1 Use backup application on host to move cartridge to mail slot. Step 2 Use HP D2D Web Management Interface to export to tape drive.

The main reason for using Export is to create more space on the HP D2D Backup System.
2. Backup applications may require the exported cartridge for the next job in their rotation scheme. Cartridge import The Web interface on the HP D2D is used to Import cartridge data from the attached tape drive to the mail slot on the HP D2D Backup System. The backup application on the host is used to move the data from the mail slot back into one of the autoloader slots. Step 1 Use HP D2D Web Management Interface to import from tape drive.
Configuration (Tape Attach) This page allows you to view physical tape drives that are attached to the HP D2D Backup System. It shows you the Vendor Name, Product ID, serial number and information about any cartridge loaded. Click Select next to a specific tape drive to display more information about its serial number and firmware revision. If there is a cartridge loaded in the tape drive, its bar code and cartridge size are also displayed (these fields have hyphens if no cartridge is loaded).
To copy to attached tape drive A copy operation may be performed upon any non blank cartridge in any numbered slot in an autoloader device or upon a non blank cartridge in a standalone tape drive device. The cartridge data is copied from the HP D2D Backup System to the physical tape drive. 1. In the Web interface select Copy/Export/Import and locate the cartridge that you wish to copy in the Cartridge list and click on the Copy button next to it. This displays the Setup page.
2. Select the attached tape drive from the pull-down list, the required verify/compare option and whether the physical cartridge should be unloaded after the operation completes. Click Start. NOTE: A Full Verify reads the data back after copy and compares it byte-by-byte with the original. A Quick Verify also reads back the data, but only ensures that it can be read. It may save some time if another tape device on the HP D2D Backup System is being accessed at the same time as the copy operation.
3. This displays the Setup page. (Or reports an error if no tape drives are currently attached to the HP D2D Backup System.) Select the attached tape drive from the pull-down list, the required verify/compare option and whether the physical cartridge should be unloaded after the operation completes. Click Start. NOTE: A Full Verify reads the data back after copy and compares it byte-by-byte with the original. A Quick Verify also reads back the data, but only ensures that it can be read.
NOTE: If you cancel the process, remember to use the backup application to move the cartridge back from the mail slot to the cartridge slot. 5. To view job progress information and any error messages, select the Status navigation topic. 6. Once the export completes successfully, the cartridge is removed from the mail slot. To import from attached tape drive An import operation may be performed on a physical cartridge in the attached tape drive.
pull-down list, the required verify/compare option and whether the physical cartridge should be unloaded after the operation completes. Click Start. NOTE: A Full Verify reads the data back after copy and compares it byte-by-byte with the original. A Quick Verify also reads back the data, but only ensures that it can be read. It may save some time if another tape device on the HP D2D Backup System is being accessed at the same time as the copy operation. No Verify is the fastest option. 3.
Once an export job has completed successfully, the cartridge is removed from the HP D2D Backup System and the mail slot will have hyphens on the Cartridges page to show that it is empty (with the option to Create a blank cartridge). NOTE: If no operations are currently in progress, a link will be provided to the Tape Attach Job History page. To cancel a job To cancel a job in progress, click Cancel . You are asked to confirm that you wish to cancel the job.
• Four types of schedule are allowed: daily, weekly monthly by day and monthly by week. • Up to 12 schedules may be created. When an export or copy scheduled job is run, it automatically overwrites the cartridge in the tape drive. If the cartridge is not blank, there is no warning and no record in the job log. NOTE: The backup application is not automatically updated with any schedules created on the HP D2D Backup System. The two are independent of each other.
5. Enter the appropriate scheduling information and click Create. Table 8 Job schedule parameters Day: This field is not relevant for daily jobs. For weekly jobs, select the day of the week. For monthly by day, select a day between 1 and 31. For months with less than 31 days, the job is always run on the last day of the month. For monthly by week, select First/Second/Third/Fourth/Last week and then the day of the week. Slot: This is the slot that holds the data that is to be copied or exported.
Compression The HP D2D Backup System does not apply hardware compression to backed-up data; HP StorageWorks tape drives do apply hardware compression. Therefore, 200 GB of data on the HP D2D Backup System will require less space on a physical 200 GB tape cartridge. If moving data to a physical cartridge for offsite storage, there is no need for concern if the data seems to utilize less space.
10 Copy using a tape drive attached to the host In this chapter: • “Requirements” on page 99 • “Using a tape drive connected to host” on page 99 • “Compression” on page 100 Requirements If you wish to copy data from the HP D2D Backup System to a tape drive connected to the host machine, you need: • A separate tape device, such as an HP StorageWorks Ultrium 460 or 448 tape drive, that can be connected directly to your host.
Server PC Server Backup Data Switch LAN SCSI Card Tape Drive Copy Data HP StorageWorks D2D Backup System Figure 39 Archiving to tape Further information It is not possible to describe how to carry out this operation because it is controlled solely from the backup application and different applications operate in different ways. HP provides a number of white papers that describe show to use this function with specific applications; see http://www.hp.com/support.
11 Restore processes In • • • this chapter: “Restore scenarios” on page 101 “Restoring single files” on page 102 “Reconnecting to HP D2D after host failure” on page 102 Restore scenarios The following table illustrates the three main restore scenarios.
Restoring from the HP D2D Backup System This is very easy and fast. Run your backup software and select the files to be restored. Although the software application is tape-based, the restore performance on your HP D2D Backup System is much faster than restoring from physical tape. Reconnecting to the HP D2D after host failure Each configured autoloader or tape drive on the HP D2D Backup System is uniquely mapped to a host. It cannot be seen by any other host on the network.
NOTE: If you have used the Secret option on the iSCSI Initiator to enter an authentication string, you must enter the same information on the Web Management Interface. See “iSCSI (Status)” on page 77. 6. On the Discovery tab, enter the IP address of the HP D2D Backup System to add it as a target portal for the host. Do not change the Port; it should be 3260. 7.
each autoloader has two devices and you must log onto each one separately. We recommend that you also select the automatic restore on boot option in the Log On... dialog. 8. Run your backup application. It should see the autoloader device on the HP D2D Backup System. Import the media into your backup application’s database and restore the latest full backup from the HP D2D Backup System.
12 Troubleshooting Use the information in this chapter to troubleshoot problems. More detailed troubleshooting information can be found at www.hp.com/support.
TIP: Some users find it helpful to enable DHCP to identify the HP D2D Backup System quickly and easily on the network and then make the IP address permanent for future use.
iSCSI Initiator fails to download The HP D2D Backup System supports the Microsoft software iSCSI initiator and requires it to be running on each host. If the host does not have the Microsoft iSCSI initiator, it will not be able to connect to the autoloader (or tape drive) configured on HP D2D Backup System and will not be able to perform backups. The Microsoft iSCSI initiator is normally downloaded from the Microsoft website during installation.

Disconnecting hosts All hosts on which the Installation wizard has been run are automatically reconnected to their device(s) when the HP D2D Backup System is restarted. If you want to disconnect a host permanently, you must: • Use the iSCSI Initiator to deselect Persistent Target, log off the target and remove the IP address, see “Advanced installation” on page 45. If you do not do this, the host will continuously try to reconnect, which may slow down the system.
• If it is accessible, there is a problem with the backup application. Certain backup applications require you to use their own drivers for both the tape device and medium changer. If this is the case, you must install the backup application drivers manually after the Installation wizard has completed. • Make sure that the iSCSI initiator is connected to the devices and log on to them, if they are not. See “Targets tab” on page 49 • If it is not accessible, rerun Discovery.
My tape drive device has run out of space It is not possible to create extra space for a tape drive device. You may be able to create an additional device for this host. Autoloaders are much more flexible because you can add slots.
Email alerts troubleshooting If you are not receiving email alerts, use the Test button on the Email Alerts page to send a test email. If this fails, make sure the email server is configured correctly. See “Email Alerts (Configuration)” on page 74 for more information. Disk troubleshooting • HP D2D Backup System runs out of space • Disk fails on the HP D2D Backup System If the HP D2D Backup System runs out of space A warning message is generated when the HP D2D Backup System reaches 90% capacity.
13 Hard disk replacement In • • • • this chapter: “Replaceable parts” on page 113 “How do I know a disk has failed?” on page 113 “Electrostatic discharge information ” on page 115 “Replacing the hard disk” on page 115 Replaceable parts The only functional parts that can be replaced in the HP D2D Backup System Backup System are the hard disks.
Look at the RAID & Disks page for more information. The disk status icon in the Physical Disks section indicates an error condition. Note also the message in the RAID Status section that warns that “RAID is still operational but failed disk should be replaced as soon as possible”. If more than one disk fails You will lose all data on the HP D2D Backup System and the message in the RAID Status section warns that there are “Too few disks to operate”.
Management Interface to help you identify the disks that have failed. You can replace the disks, rebuild the RAID array and use the HP D2D Backup System as a new appliance. Electrostatic discharge information ESD can damage static-sensitive devices or microcircuit. Proper packaging and grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage, observe the following precautions: • Transport products in static-safe containers such as conductive tubes, bags, or boxes.
2. The information in the Physical Disks section identifies which disk has failed. The serial number is the only unique identifier of the disk. It is very important to make a note of the physical disk number and the serial number as they appear on this screen BEFORE you remove the disk. The serial number is the only way that you can be sure you are replacing the correct disk. CAUTION: If you replace the wrong disk, you could lose all your data. 3.
Figure 41 Removing the access panel 6. Press in on the two bottom tabs (1) on the side of the bezel so that they release from the chassis. Press in on the upper tab on the side of the bezel so that it releases from the chassis. The bezel will rotate out slightly (2). Pull the bezel (3) away from the front panel. Figure 42 Removing the front bezel 7. Remove the screw (1) from cover that secures the drives so that you can remove the failed drive. Pull the cover (2) away from the drives.
Figure 43 Removing the disk cover 8. The diagram on the lid of the HP D2D Backup System shows how the disks are cabled. a. Check that the disk identified as failed in the Web Management interface is plugged into the corresponding SATA port. For example, if Disk 1 is shown as failed, trace the cable to the SATA port. It should be in SATA Port 1. (If it is not, you may need to remove several disks to locate the failed one, identified by the unique serial number.) b.
NOTE: If the replacement drive is not supplied with screws, remove the screws (two on each side) from the failed drive. Figure 45 Removing the hard drive 10. Replace the failed disk with the new disk. Insert the four drive screws (two on each side) into the hard drive (1). If these are not supplied with the new disk, use the screws from the failed disk. Slide the new hard drive (2) into the selected bay until it clicks into place.
Figure 47 Replacing the drive cover 12. Insert the two hooks on the right side of the bezel into the rectangular holes on the chassis (1). Rotate (2) the bezel into place so that the three tabs on the left side of the bezel snap into the slots on the chassis. Figure 48 Replacing the bezel 13. Use two hands to place the access panel flat against the chassis (1), the back of the access panel extending about 2.5 cm (1.0 in) behind the back of the server.
Figure 49 Replacing the access panel 14. Reconnect the network cable and the power cord. 15. Power up again by pressing the Power on switch on the front of the unit. 16. You now need to rebuild the RAID array. Select Disk & RAID on the Web Management interface. 17. The status of the failed disk should now be OK and there is a message to say that the disk is available but not yet part of the RAID system. Click Add Disk to add the disk to the RAID array.
NOTE: If several disks fail, the RAID state will still display a fault, but you are given the option of initializing the RAID array. This will make the HP D2D Backup System usable again, but you will have lost your data. Replacing a complete unit If you are sent an empty unit as a replacement, you must transfer the disks from the old unit into the new unit. Follow the steps outlined in the previous section to move each disk into the new unit. Further advice is available on the Support website, www.hp.
