Backup solutions
The Direct Backup Engine feature of the HP Surestore Disk Array XP with
use of a backup application provides “server-free” backup solutions
between the disk array and backup devices such as tape devices and disk
devices. Direct Backup Engine enables nondisruptive backup directly from
disk to tape (or disk) in a storage area network (SAN) environment,
eliminating server CPU and I/O overhead during actual movement of data
and shortening the time required for backups. Users can perform copy
(backup) operations on the data (in unit of blocks) stored on the
multiplatform XP disk array via fibre-channel interfaces by copying the
data directly onto the users' backup devices (such as tape devices and
disk).

Figure 1. Direct Backup Engine
Direct Backup Engine supports the Extended Copy commands issued from
the host server (with a backup application installe d) to the XP Disk Array.
To use Direct Backup Engine, you must enable (install) the Direct Backup
Engine feature option on the XP Remote Console PC. You will also use
the LUN Manager feature option on the XP Remote Console PC to set the
fibre-channel ports required for the Direct Backup Engine operations. For
instructions on installing the Remote Console PC and LUN Manager
remote console software, please refer to the product documentation
Direct Backup Engine only assists backup operations for the data stored on
the XP Disk Array by enabling the XP Disk Array to receive the Extended
Copy commands issued by the open-system host server, and copy the
specified data directly to a specified backup device. Direct Backup Engine
is provided as a XP remote console option (license key), but to perform
Direct Backup Engine) operations, a backup application, which actually
issues the Extended Copy commands to the disk array, is also required in
the host server.
Generally, the term “Extended Copy command” refers to a block-oriented
command that can cause device-to-device data movement. In this
document, the term “Direct Backup Engine operations” sometimes refers
not only to the XP Direct Backup Engine feature alone, but also the entire
backup procedures including LUN Manager operations for setting the
ports and the Extended Copy commands issued from the host server. For
information and instructions on performing LUN Manager operations,
please refer to the product documentation. Fo r info rm ati on and inst ruc tion s
on performing the Extended Copy command operations on the host server,
please refer to the manual of the backup application, or contact your HP
account team.

Open-System Host Server
The Direct Backup Engine operations involve the open-system host server
with a backup application installed. The host server executes the Extended
Copy commands to copy the specified data in the XP Disk Array to the
specified backup devices (such as tape devices and Disks). The host server
can remain online during the actual movement of data from disk to tape or
disk; therefore the server CPU and I/O resources are always available to
other operations and applications. The host server must be connected to a
target port in the XP Disk Array via the fibre-channel interface.
Note: For the host server requirements, see the systems requirements.
14 HP Surestore Direct Backup Engine XP: User’s Guide
XP Disk Array and Volumes (LUs)
The Direct Backup Engine operations involve the XP Disk Array. Direct
Backup Engine supports all physical disk drive options and RAID-level
configurations for the XP Disk Array. The XP Disk Array contains the
original volumes (LUs) for backup, and remains online to the host server
all the time. Also, the XP Disk Array must contain at least one port group,
which consists of a target port for receiving the Extended Copy commands
from the host server and an initiator port for copying the specified data to
the backup device. Also, the LUN Manager option on the Remote Console
PC is required to set the port groups.
Direct Backup Engine supports all LUs that can be identified by the
backup application on the host server. When the Extended Copy command
is issued to the XP Disk Array from the backup application on the host
server, information about the data (files) that you want to copy is reported
to the XP Disk Array by the Extended Copy command. For example, the
Extended Copy command instructs the XP Disk Array about the LUN in
which the data is stored, the starting Logical Block Address (LBA), and
the data size to be transferred.
to copy depends on the backup application on the host server.
Note: How you specify files that you want
Figure 3 shows an example of how the Extended Copy command specifies
the data to be copied.

Backup Devices
Direct Backup Engine supports tape devices and disk devices as backup
devices for the XP Disk Array.
For the backup device requirements, see the section on system
requirements.
Backup solutions 17
Port Groups (Initiator Ports and Target Ports)
You must set a minimum of one port group in the XP Disk Array before
you can perform the Direct Backup Engine operations. Setting a port group
reduces the time for specifying the copy destination, thus improving
performance of direct copy from the disk to the backup device. In each
port group target port(s) and initiator port(s) are registered.
• Target ports are the dedicated fibre-channel interface ports on the XP
Disk Array, to which the host servers are connected. A target port
receives the Extended Copy commands issued by the connected host
servers and transmits the com mands directly to the XP Disk Array.
Any installed fibre-channel interface ports (packages) of the XP Disk
Array can be set as target ports.
• Initiator ports are the dedicated fibre-channel interface ports on the
XP Disk Array, to which the backup devices are connected. Fibrechannel interface ports (packages) which support Fibre Channel
Continuous Access XP (FC/CA XP) of the XP Disk Array can be set
as initiator ports.
FC/CA XP is the Continuous Access XP feature option which supports
remote copy operations via fibre-channel interfaces.
If you use both Direct Backup Engine and FC/CA in the same XP Disk
Array, you cannot set a Continuous Access RCU target port as a Direct
Backup Engine copy destination. You must use an ordinary target port as
the copy destination.
18 HP Surestore Direct Backup Engine XP: User’s Guide
Fibre-Channel Cable Connections
The Direct Backup Engine connections are the physical paths used by the
XP Disk Array to communicate with the backup devices. The XP Disk
Array and backup devices are connected via fibre-channel interface cables.
When fibre-channel interface (multimode shortwave) connections are
used, two switches are required for distances greater than 0.5 km (1,640
feet), and distances up to 1.5 km (4,920 feet, 0.93 miles) are supported.
When fibre-channel interface (single-mode longwave) connections are
used, two switches are required for distances greater than 10 km (6.2
miles), and distances up to 30 km (18.6 miles) are supported.
Backup solutions 19
XP Remote Console PC and Software Options
Before you can issue the Extended Copy commands from the host server
using the back up application, you must install the Direct Backup Engine
and LUN Manager remote console software options (license keys) from
the Remote Console PC, and set the Direct Backup Engine ports. Please
refer to the remote console documentation for ins truct i ons on install ing an
option.

Preparing for Direct Backup Engine Ope r ations 25
Port Types of Direct Backup Engine and Fibre Channel Continuous Access
XP
For the FC CA operations, three port types are required: ordinary target
port, MCU initiator port, and RCU target port. The initiator port and target
port of Direct Backup Engine are equivalent to the MCU initiator port and
ordinary target port of FC CA in the primary MCU respectively. When the
same FC CA secondary (RCU) is used as the Direct Backup Engine
backup device, the RCU target port of FC CA cannot be specified as the
backup destination of Direct Backup Engine. However, when the array,
which performs the Direct Backup Engine operations, is the same as the
FC CA secondary RCU, the RCU target port of FC CA can be used as the
target port of Direct Backup Engine. Please refer also to chapter 2 for the
ports of Direct Backup Engine and FC CA.
Note: FC CA is the XP Continuous Access XP feature option that supports
remote copy operations via fibre-channel interfaces. Please refer also to
the product documentation for Continuous Access operations.
Table 1 shows the relationship between port types (attributes) and the
number of connections.
Table 1. Port Types and the Maximum Number of Connections
No. Port Type Connectable Hosts Connectable MCUs Connectable Targets
1 Ordinary Target 255 0 2 RCU Target 128 16 3 MCU Initiator - - 64
The restrictions and conditions on changing the port types are as follows:
The type of port, which belongs to any port group, cannot be changed.
Initiator ports cannot be changed to RCU target ports of FC CA.
If you want to change an ordinary target port or RCU target port to an
initiator port, the port package (CHF PK) for FC CA is required.
If you want to change an ordinary target port to an initiator port, make
sure that no SCSI path is assigned for that ordinary target port.
If you want to change an RCU target port to an initiator port or an
ordinary target port, make sure that no CA path is assigned between
the MCU initiator port and that RCU target port.
If you want to change an initiator port to an ordinary target port, make
sure that no CA logical path is assigned for that initiator port.
Note: If the conditions above are not met, an error will occur.

one initiator port and one target port (or RCU target port) must belong to a
port group.
The selected ports are added to the selected port group, and displayed in
the port list box on the Port Group tab.
Deleting Ports from a Port Group
Caution: Make sure that no I/Os such as the Extended Copy commands
are being executed from the host server to the port(s) before deleting the
port(s).
You can delete unneeded port(s) from a port group. The XP Disk Array
automatically checks I/Os from the host server to the port(s) to be deleted
before deleting the port(s). If you want to delete the port(s) forcibly
without I/O check by the array, select the Not execute the I/O check
checkbox on the Delete Port panel.
To delete one or more ports from a port group:
1. On the Port Group tab of the LUN Manager panel, select a port group
in the Port Group tree view.
2. In the port list box, select one or more ports that you want to delete.
3. Select the Delete button. A message appears, asking you whether you
want to delete the selected ports.
4. Take either of the following steps:

Troubleshooting
The user is responsible for the operation and normal maintenance of the
Remote Console PC. Here are some guidelines for troubleshooting the
Remote Console PC:
4
• Check the cabling and the LAN. Verify that both the computer and
LAN cabling are firmly attached, and that the LAN is operating
properly.
Reboot the PC. Close any programs that are not responding. If necessary,
reboot the PC and restart the Remote Console program. (If possible, first
close all open programs before rebooting.)
by the XP Disk Arrays cannot be logged onto the Remote Console PC
when the PC is powered off. Reconnect to the same array(s) and verify the
status of the data.
• Check for any General Error Conditions. Table 5 describes some
general error conditions, along with the recommended resolution for
each item. If you are still unable to resolve an error condition, call the
HP Technical Support Center for assistance (see the section on
“Calling the Support Center” for contact information).
Note: If you are unable to resolve an error condition, first copy the XP
Remote Console configuration information onto floppy diskette(s) using
the FDCOPY function. Contact the HP Technical Support Center, and give
the information on the floppy diskette(s) to the HP service personnel. See
Remote Console User’s Guide for instructions on how to use the FDCOPY
function.
Caution: The R-SIMs reported

Verify that the SN (serial number) is correct. If not, delete the subsystem, and then add the subsystem
using the correct SN. If RMCMAIN still cannot connect, check the settings on the Windows network
control panel, and use PING to test the LAN connection. If RMCMAIN still cannot connect, exit
RMCMAIN, restart the PC, start RMCMAIN, and try again. If RMCMAIN still cannot connect, reinstall
the RMCMAIN software. If the problem persists, please call the HP Technical Support Center.
Exit RMCMAIN, close all other applications, and then restart the PC. If the problem persists, verify that
the PC’s operating system and LAN hardware and software are properly configured, and reinstall the
RMCMAIN software. The user is responsible for maintaining the Remote Console PC.
Open the R-SIM View panel, and sort the R-SIMs by name to view the R-SIMs by subsystem. If there
are any serious- or acute-level R-SIMs, call the HP Technical Support Center.
