If the HP D2D Backup System has been conﬁgured incorrectly

If you cannot connect to the HP D2D Backup System using the Web Management interface, it may have been conﬁgured incorrectly. Run the Discovery Engine to check the IP add ress of the HP D2D Backup System and, if necessary, select it again from the list of available HP D2D Backup Systems. If you still cannot connect to it, check that you have conﬁgured the iSCSI Initiator correctly, see also “Discovery tab” on page 53.

If the network setup has been changed

If the network infrastructure changes, you may need to update the HP D2D Backup System network settings to allow hosts to continue to connect. Run the Discovery Engine and change the network settings in accordance with your new infrastructure.

You c an also use the Web Management Interface to modify these settings directly on the HP D2D Backup System, aslongasthisisdonebeforethe infrastructure changes are made.

Once the network settings of the HP D2D Backup System have been changed, you must also change the iSCSI Initiator for each host.

4. Locate the IP address for the port(s) and make a note of it.

5. Use an iSCSI Initiator to enable the host to connect to devices on the HP D2D, see also

“iSCSI Initiator” on page 49. In the web browser on the host machine, type in the I P address of the

HP D2D to connect to it.

iSCSI Initiator

NOTE:

If you have a FC product, you may conﬁ gure it to have amixture of FC andiSCSI attached devices. If

you are conﬁguring y our HP D2D to have iSCSI devices (for hosts attached via the LAN ports), this section is relevant. However, if you are conﬁ guring it to have only FC network devices (attached via the

FC ports), it is not necessary; you use the Web Management interface to c reate FC devices, see

“To create a new device” on page 72.

iSCSI is a protocol for sending SCSI commands via Ethernet. It deﬁnes how SCSI packets are translated to Ethernet packets and connects to the required devices. An iSCSI initiator may be hardware or software andshouldberunning on each host. Ifthe host does not haveaniSCSI initiator, it will notbeableto connect to the library conﬁgured on the HP D2D Backup System and will not be able to perform backups.

The HP D 2D Backup System supports the Microsoft software iSCSI initiator which ca n be retrieved from the Microsoft website.

Figure 26 iSCSI Initiator download page

3,x86

Use with amd ® 64-bit processors and with Intel ® em64t processors, when running a 64-bit version of the Windows operating system.

Use with ia-64 processors, such as Itanium and HP Integrity. Use with 32-bit processors or 64-bit processors running 32-bit Windows, such as

Windows XP and Server 2003.

If you download the wrong version, it will not install. The simplest way of ensuring you download the

correct version is to run the Installation wizard from the HP StorageWorks CD-ROM because it

automatically checks which is the appropriate version for your host.

NOTE:

The Microsoft Vista operating system includes the Microsoft iSCSI Initiator. It can be run from the Control Panel in Classic Mode.

Manual iSCSI initiator installation

The Installation wizard could fail for the following reasons:

• The host machine does not have an internet connection

• Firewall restrictions prevent this process

• Microsoft has relocated the iSCSI initiator ﬁles to a different address on its website.

• The process times out due to a slow connection

• The maximum number of drives/libraries have been conﬁgured on the HP D2D

If the process fails:

1. On a machine that supports an external internet connection, go to the Microsoft website and

search on "iSCSI initiator"

2. Select the result that takes you to the Download page and choose the download tha t is appropriate

foryourhost.

3. Download the iSCSI initiator and install it on the host, accepting all the default settings.

The iSCSI Initiator and Authentication

Authentication is not required for the HP D2D, but it is suppor ted for those companies that have an IT policy that requires them to use authentication ﬁelds on the iSCSI Initiator and also ensure that Management Interface. This enables the Initia target device to log into the Initiator.

The authentication method supported on D2D products is C H AP. It relies on a "secret" known only to the

target and initiator. The size of the CHAP s

entered in exactly the same format in both the Web Management Interface and the iSCSI initiator. An ’Authentication Failure’ message will occur if the same ’secret’ and ’user name’ information are not

entered into the iSCSI Initiator screen and the Web Management Interface. Further details on

authentication and CHAP can be found within standard iSCSI protocol documentation. The recommended process if you wish to enable authentication is:

1. Create the devices on the Web Ma nagem ent Interface.

2. Set up the Targets in the iSCSI Initiator.

3. Connect to the devices using the CHAP user name and secret that you conﬁgured on the Targets tab.

Fibre Channel topologies

The HP D2D Backup System supports a s w itched fabric ﬁbre channel topology. A switched fabric topology allows nodes to talk directly to each other through temporarily established

direct conn for each communication between nodes. Because of this, switched fabric topologies provide signiﬁcantly more performance and scalability than arbitrated loop topologies.

Switched fabric conﬁgurations are implemented with Fibre Channel switches. Switches may be cascaded or

meshed together to form larger fabrics.

Other topologies will be supported at a later date. Please refer to h

Zoning

Due to complexities in multi-hosting tape devices on SANs, it is best to make use of zoning tools to help keep the backup/restore environment simple and less susceptible to the effects of changing or problematic SANs.

Zoning provides a way for servers, disk arrays, and tape libraries to only see what hosts and targets they need to

• Limiting unnecessary discoveries on the HP D2D Backup System

• Reducing stress on the HP D2D Backup System and its library devices by polling agents

• Reducing the time it takes to debug and resolve anomalies in the backup/restore environment

• Reducing the potential for conﬂict with untested third-party products

Zoning may not always be required for conﬁgurations that are already small or simple. Typically the bigger the SAN is, the more zoning is needed. HP recommends the following for determining how and

• Small fabric (16 ports or less)—may not need zoning.

• Small to medium fabric (16 - 128 ports)—use host-centric zoning. Host-centric zoning is

implemented by creating a speciﬁc zone for each server or host, and adding only those storage elements to be utilized by that host. Host-centric zoning prevents a server from detecting any other devices on the SAN or including other servers, and it simpliﬁes the device discovery process.

• Disk and tape o n the same pair of HBAs is s upported along with the coexistence of array

multipath software (no multipath to tape or library devices on the HP D2D Backup System, b ut coexistence of the multipath software and tape devices).

• Large fabric (128 p orts or more)—use host-centric zoning and split disk and tape targets.

Splitting d isk and tape targets from being in the same zone together will help to keep the HP D2D Backup System free from discovering disk controllers which it doesn’t need to see. For optimal performance, where p ractical, dedicate HBAs for disk and tape.

NOTE:

Overlapping zones are supported.

Fibre Channel connection

Backup and restore is supported over both Ethernet networks and Fibre Channel SAN. However, the Web Management Interface always requires an Ethernet connection. If you have the FC product, you must also connect to LAN port 1 and should run the Installation wizard to connect to and discover your HP D 2D Backup System and to create a library device on the HP D2D before you can start to back up from the FC host. The FC product is supplied with the correct FC card pre-installed. It does not include FC cables.

Connect to LAN Port 1, as described in “Ethernet connection” on page 30.

Emulation types for tape devices

HP D2D products emulate a range of physical tape devices, these are either Tape Autoloaders or Tape Libraries. Supported emulation types are listed below:

The Web Management Interface

Page 71

• HP 1x8 G2 Autoloader: This is a single Ultrium tape drive autoloader with a maximum of 24 cartridge

slots. It should be used for simple rotation schemes where a single backup job is to run at a time. This emulation type is widely supported by backup applications.

• HP MSL2024 Library: This is a tape library d evice with a maximum of two embedded Ultrium tape

drives and 24 cartridge slots. It should be used when implementing rotation schemes which involve simultaneous backup jobs to t wo devices. This emulation type is widely supported by backup applications.

• HP MSL4048 Library: This is a tape library device with a maximum of four embedded Ultrium tape

drives and 48 cartridge slots. It should be used when implementing rotation schemes which involve simultaneous backup jobs to more than two devices or those that use a large number of cartridges devices. This emulation type is widely supported by backup applications.

• HP D2DBS Library: This is a tape library device with a maximum of four embedded Ultrium tape drives

and

96 cartridge slots. If it is supported by your backup application, this is the preferred emulation type to be used because it does not emulate any physical library types in existence and is, therefore, clearly identiﬁable as a D2D device. It is the most ﬂexible emulation type available; however, backup application support varies by software vendor.

NOTE:

Symantec prefer their customers to use this emulation type with BackupExec and Netbackup.

Libraries, slots and storage capacity

Each slot conﬁgured commits 3 GB of physical disk space, regardless of what value has been conﬁgured for the ma ximum cartridge size. This ensures that there is always sufﬁcient space to ﬂush buffers and there is

never data in memory that cannot be written to cartridge. The remainder of the conﬁgured maximum capacity is used only as needed, but the initial 3 GB is permanently committed. Therefore, only conﬁgure the

number of slots that you actually require. If you conﬁgure a MSL G3 Series (2x24) with 24 cartridges, you should be aware that you have committed 72 GB of disk space — even when no data is written. Only do this,ifyou aresureall slotswillbeused.

User recommendations

To avoid over-allocation of disk space and the possibility of running out of disk space for non-user data:

• Only conﬁgure the libraries that you need

• Only conﬁgure the number of cartridges that you are likely to need

You can add cartridges at a later date to expand the system and remove individual blank cartridges from a library without deleting the whole library, but cannot remove cartridges that have been written to. See “Cartridges (Conﬁguration)” on page 74.

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 times you can resize cartridges are when you ﬁrst create a library or when you 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. Similarly, the erase function on most backup applications does not return the cartridge to a completely b lank state.

The Max Size defaults to the appropriate capacity for the drive emulation type selected on the Devices tab, but if the Used Size is Blank, you can edit this value. The maximum value allowed is 800 GB.

Click Edit for the appropriate slot. Select a value from the drop-down menu and click Update.

NOTE:

The maximum size indicates the physical disk space available for that slot; it will only be committed when data is written to it. Changing the maximum space does not affect actual disk usage or save disk space, but may be useful if you know you will be moving data to a physical tape with a smaller cartridge capacity.

• If you use the Create icon 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 icon on an empty mail slot, you can use the backup application to move

theblank,new cartridgetoanempty cartridgeslot, without having to run an inventory. This saves some processing time.

You may need to restart your services to see the new cartridges.

The Web Management Interface

NOTE:

When you import a cartridge, you need an empty mail slot and an empty cartridge to which the backup application can move the imported data. Therefore, you may wish to leave a slot whose cartridge has been exported empty, rather than creating a new cartridge. Or to create a slot, edit the Total No Of Cartridge Slots on the Devices page, see “To edit device details”onpage 71.

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 eight 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. Email alerts are also generated for tape attach activities, when there is a separate tape drive connected to the HP D2D Backup System and the user is importing data from it, copying or exporting data to it, or scheduling tasks to carry out these activities.

The HP StorageWorks D2D Backup System uses Simple Mail Transfer Protocol (SMTP), which is the established standard for transferring mail over the internet. Microsoft Exchange has a virtual SMTP server available which can be used to receive these emails and forward onward if necessary. UNIX and

Linux operating systems have a Sendmail program included. Sendmail uses the SMTP protocol to

receiveand,if necessary,forward e-mail messages. To conﬁgure email settings, the HP D2D Backup System must be on the same network as an SMTP

server that it can use.

8 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 net work. If your backup

application supports the copying of data between devices, you can then use the backup application to move data from the HP D2D Backup System to physical tape. This option is described in “Copy using a tape drive a ttached to the host” on page 109.

Requirements for connecting a tape drive to the HP D2D

To use this facility you need:

• A tape drive, such as an HP StorageWorks Ultrium device. This should be an external or rack-mount

tape drive. Both SAS and SCSI tape drives are supported.

• A host bus adapter, HBA, for the tape drive connection (because there are no embedded SAS or SCSI

ports). You must purchase and install the HBA before connecting the tape drive.

Please refer to h supported host bus adapters and tape drives. For instructions on attaching the tape drive, please refer to “Attaching a physical tape drive” on page 37.

NOTE:

Physical tape drives attached to the HP D 2D Backup System can only be accessed by the HP D2D Backup System, using the Tape Attach pages. They do not appear as attached network devices to the host system.

Cartridge copy

The backup application on the host is used to back up data to a cartridge on the library device (or to a standalone tape drive device) in the HP D2D Backup System. The Web Management Interface on the HP D2D

Backup System is used to Copy the cartridge from the HP D2D Backup System to the at tached tape

Whyuse theCopyfunctionality?

Copy creates two instances of the same cartridge; one stored on the HP D2D, the other o n physical tape. Logically these are the same cartridge and the backup application has no awareness that there are two copies. If data from this cartridge is required for restore, the backup application will always restore the data from the HP D2D if it is available. The physical cartridge is, therefore, an additional copy that will be

required only if the HP D2D is not available.

When would Copy be used?

Cartridge copies are likely to be appropriate when the user wishes to use the HP D2D Backup System for all

foreseeable restore processes but requires an additional offsite copy for insurance or data security purposes. This may mean that weekly, monthly and yearly cartridges are copied. Weekly and monthly physical cartridges may be rotated; the cartridges on the HP D2D Ba ckup System are overwritten after a period of time. Yearly cartridges may be kept indeﬁnitely. Clear labeling of the cartridges in this case is essential because the backup application may overwrite the cartridge on the HP D2D Backup System and, therefore, lose any knowledge of the existence of the physical tape cartridge.

Why use the Export functionality?

The main reason for using Export is to create more space on the HP D2D Backup System. If deduplication is enabled creating offsite backups, because it is controlled solely from the Web Management Interface and will not impact any tape rotation strategy. Export involves use of the b ackup application. It is directly analogous to moving a cartridge in a physical library to a mail slot (impor t/export element) so that the backup administrator can take it offsite or put it into a ﬁresafe. Only a single copy of the cartridge exists. It is on physic fully a the

The main advantage of Export is that it frees up disk space on the HP D2D Backup System if deduplication is disabled on the library device. However, care must be taken to ensure that future backups do not fail. For example, if a weekly backup tape is "exported", it will not be available for append or overwrite

When would Export be used?

Cartridge exports are likely to be used when the user wishes to free up space on a library device where deduplication is disabled on the HP D2D Backup System by exporting to physical tape a cartridge that is

used infrequently. For example, if a rotation scheme uses twelve monthly tapes, it is safe to export a monthly tape from two months ago because it will not now be required (except for infrequent restores) for another ten months. The same applies to yearly tapes which may never be required again as they are kept forever.

When would I restore from an exported cartridge?

Restoring from an "exported" cartridge has a higher likelihood than from a copied cartridge, because the data required, the backup application will ask for the cartridge to be re-imported into the HP D2D before it can be

1. Restores may take longer if a physical cartridge is required for the restore.

2. Backup applications may require the exported cartridge for the next job in their rotation scheme.

Compression

When you are moving data from the HP D2D to physical tape, it is important to be aware that the cartridge maximum size is the native size (without compression). HP StorageWorks tape drives apply hardware compression, therefore, the data from the HP D2D Backup System is likely to require less space on a

physical tape cartridge. When moving data to a p hysical cartridge for off-site storage, there is no

need for concern if the data seems to utilize less space. The capacity quoted for physical media assumes that the tape drive will be able to compress your data

and reduce the ﬁle sizes by 50%, but this can be achieved only if your d ata is not already compressed. Forexample,JPEGpictures, movies,music or ZIP ﬁles, are already in compressed formats: spreadsheets, text ﬁles, high-resolution graphics are not. Most users have a mixture of compressed and uncompressed data and seldom achieve 50% compression.

Some users may choose to enable software compression from their backup application to increase the

storage space available to the backup application, but this can make backup jobs slower to run. However, once software compression has been applied, the data is not further compressed when it is exported to a physical tape directly attached to the HP D 2 D Backup System. This ensures that the user knows exactly how much physical cartridge space is required for export or copy.
