Introduction 11

How the Interface Manager (IM) Works

The IM provides connectivity between a Fibre Channel (FC) switched fabric
(FC-SW) or Fibre Channel arbitrated loop (FC-AL) and up to 20 Ultra-2 SCSI
buses.

The IM contains slots for up to eleven (one slot is reserved for future expansion)
Fibre Channel cards. Each card connects a FC port to two Ultra-2 SCSI ports.
The IM also contains a Remote Management Card (RMC) in slot 1, and a
controller card in slot 2. The RMC provides the user with a serial port for initial
setup, as well as Telnet and Web Administrator - HTTP access to any of the
cards in the IM.

Each FC card translates the FC protocol (FCP) to and from the SCSI protocol so
that FC and SCSI devices can communicate. The FC card attaches to a FC host,
hub, or switch and transfers the command, data, and status information to
SCSI targets. Packets are transferred transparently by the IM between a host
and targets and vice versa.

SCSI and Fibre Channel connectors are accessed from the front of the IM.
Ethernet and serial ports provide the means for configuring and managing the
IM. A power connector is located on the front of the Interface Manager.

Processing SCSI Information

The following section describes how the Interface Manager (IM) processes SCSI
information when attached to Fibre Channel (FC) hosts.

1. A FC host issues a command. The FC host encapsulates the SCSI
command in the FC protocol and sends the packet to the IM.

2. The FC card in the IM receives the packet, interprets the FC information,
and places the packet in buffer memory.

3. The IM’s processor interprets the information and programs a SCSI
controller to process the transaction.

4. The SCSI controller sends the command to the SCSI device (target).

5. The SCSI target interprets the command and executes it.

6. Data flows between the FC host and SCSI target through payload buffers.

7. Response information flows from the SCSI target back to the FC host.

24 Overview of the Interface Manager (IM) Configuration Chapter 2

Choosing the Right Configuration

The factory default settings of the Interface Manager (IM) permit the type of
configuration shown in Figure 3 on page 26 (standard configuration) to work
without any initial changes to these settings. The IM settings may need to be
changed for expanded configurations (see Figure 4 on page 27) or certain
application requirements.

Figure 3 Example of a Standard Configuration in a 20/700 Tape Library

26 Choosing the Right Configuration Chapter 2

Figure 4 Expanded Configuration

Chapter 2

Chapter 2 Choosing the Right Configuration 27

A standard configuration may involve several Fibre Channel (FC) hosts
connected to multiple FC cards. These FC host systems may be connected to
the cards either in a point-to-point (PPP) fashion or through a FC switch. Each
card is then connected to two SCSI tape drives.

The library’s robotics controller may be daisy-chained with one of the SCSI
tape drives or connected directly to an available FC interface card SCSI port,
or direct connect SCSI to host.

Note When daisy-chaining the library’s robotics controller to any LVD

Fibre Channel Port Mode

The IM’s Fibre Channel ports can operate in either NL_Port or N_Port mode.
The IM has the ability to autosense and choose between these modes of
operation.

■ NL_Port - The IM can share a FC Arbitrated Loop with other NL_Port

devices (or HBAs). A single FC switch port acting in FL_Port mode can
also be connected to the loop.

■ N_Port - The IM does not employ the arbitrated loop protocol. This allows

for a more efficient connection to a single FC switch port acting in F_Port
mode.

Some FC switches (such as the HP/Brocade SilkWorm) support either FL_Port
and F_Port modes with autosensing capabilities. Other switches (such as the
HP Surestore Director) only support the F_Port mode. When connecting directly
to a FC switch port, configure the IM in N_Port mode for a more stable and
efficient connection.

Port mode can only be set in the FC Configuration menu via the Telnet
interface. See Configuration Using the Telnet Interface on page 38.

tape drive, the library must have the LVD to HVD converter
(A6324A) installed.

28 Choosing the Right Configuration Chapter 2

Fibre Channel Arbitrated Loop Addressing

On a FC arbitrated loop, each device appears as an Arbitrated Loop Physical
Address (AL_PA). To obtain an AL_PA, two methods called soft and hard
addressing can be used by the IM. The IM can be configured to use either
method.

Hard Addressing

Hard addressing is recommended for FC arbitrated loop environments where it
is important that the FC device addresses do not change. Device address
changes can affect the mapping represented by the host operating system to
the application. An example of such an environment would be a tape library
installation, where the application configuration requires fixed device
identification for proper operation. Hard addressing ensures that the device
identification to the application remains constant.

When acquiring a hard address, the IM attempts to acquire the AL_PA value
that was specified by user configuration. If the desired address is not available
at loop initialization time, the IM will come up on the FC loop using an
available soft address. This allows the loop to continue to operate. This
situation would occur when another device on the arbitrated loop has
acquired the same address as that configured on the IM.

When connected to a FC switch, the IM is identified to the switch as a unique
device by the factory programmed World Wide Name (WWN).

Soft Addressing

Soft addressing is recommended for FC fabric environments where the FC
interface card does not employ the Arbitrated Loop protocol. In these
environments, an AL_PA is not used as part of the device address, so soft
addressing allows the FC interface card to operate as an N_Port. Soft
addressing is recommended primarily for switched fabric configurations.

When acquiring a soft address, the FC interface card acquires the first
available loop address starting from address 01 and moving up the list of
available AL_PAs to EF. In this mode, the FC interface card automatically
obtains an available address and participates on the FC loop, as long as there
is at least one address available on the loop that is connected to the IM. FC
supports up to 126 devices on an arbitrated loop.

Chapter 2

Chapter 2 Choosing the Right Configuration 29

Host Device Configuration

The host system using a FC host bus adapter (HBA) will typically map FC
devices into the existing device mapping scheme used by that operating
system. (Refer to your HBA manual for the mapping table.) The FC usually
maps FC addresses to SCSI target addresses. In such a configuration, the IM
corresponds to a bus:target identifier, with the SCSI devices attached to the IM
appearing as logical units (LUNs). In addition, operating systems can extend
the available SCSI limit of 15 Target IDs per bus.

Although this is not an issue for the operating system or most applications,
there are cases where older applications or Windows NT can have
expectations about what are valid SCSI IDs, and not deal correctly with certain
mappings. In particular, applications have been seen to exhibit difficulties
addressing Target IDs greater than 15 (e.g. 16 and up). This problem can be
resolved by configuring the IM to use hard addressing, and setting the AL_PA
used by the IM to a value that the HBA will map to, with an ID having a value
less than 16.

SCSI Addressing

A FC interface card appears on each SCSI bus as a single initiator. The default
initiator ID is 7. No other device on the SCSI bus may use this address. Note
that the FC host itself is not connected to the bus. Their SCSI operations are
passed down to the individual SCSI target devices through the use of the IM’s
SCSI Initiator ID.

The IM negotiates for the maximum values for transfer rates and bandwidth on
a SCSI bus. If an attached SCSI device does not allow the full rates, the IM will
use the best rates it can negotiate for that device. Negotiation is on a device
specific basis, so the IM can support a mix of SCSI device types on the same
SCSI bus.

Buffered Tape Writes

Buffered Tape Writes is an option designed to enhance system performance.
By returning status on consecutive write commands prior to the tape device
receiving data, Buffered Tape Writes remove the latency of waiting for
responses from the tape device. In the event that data does not transfer
correctly for any reason, the interface card will return a check condition on a
subsequent command.

30 Choosing the Right Configuration Chapter 2

Address Mapping

Commands other than Write are not issued until status is received for any
pending Write. Also, status is not returned until the device completes the
command. For instance, when a synchronizing command is sent to the drive,
such as sending a Write File mark, a good status means all prior commands
have been successfully completed and data has been successfully written to the
medium. This is appropriate for such tasks as file backup/restore.

Chapter 2

Note If the application requires confirmation of individual blocks

being written to the medium, such as audit trail tapes or log
tapes, this option should be disabled via the Telnet interface.

SCSI targets are selected by mapping the appropriate values into the FCP LUN
field, and correlating a FC LUN value to a SCSI bus:target:LUN value. The FC
interface card acts as a single initiator on each SCSI bus, fixed at ID 7. All
commands passed through to a SCSI bus originate from this SCSI ID.

FC to SCSI Address Mapping can be independently set for each fibre interface
card in the IM.

Two variations of Indexed Addressing are possible when mapping SCSI targets
to FC initiators (hosts).

By default, the mapping table on each interface is created every time the IM is
power cycled or the individual interface is rebooted. This method is auto­indexed.

If auto-indexed mode is disabled, then the mapping table already stored in the
IM’s memory will be used. This method is fixed-indexed.

Chapter 2 Choosing the Right Configuration 31

Auto-Indexed Mapping

This is the default method of operation. Discovery of SCSI devices is performed
at every startup (power up, or reboot). As devices are discovered, they are
added to the FC-to-SCSI mapping table. The FC LUN numbers are assigned
sequentially. The mapping table is stored in FLASH memory. An example of a
FC-to-SCSI map for three SCSI devices is shown in Table 1.

Table 1

Fibre Channel SCSI

FCP LUN Bus Target LUN

0 000

1 010

2 120

In this method, the host system detects every attached device without voids in
the FCP LUN list, allowing full device discovery to the host. This allows easy
configuration in environments where device ordering is not important, and hot
plugging of SCSI devices will not occur.

Example of a Fibre Channel-to-SCSI Mapping

Fixed-Indexed Mapping

This is an optional method of operation. Although the interface performs
discovery of SCSI devices at startup, the results of this discovery are not utilized
to create the FC-to-SCSI mapping table. Instead, the copy of the mapping table
stored in FLASH memory is used.

Fixed-indexed is recommended for environments where SCSI device
configurations may change, and a fixed mapping from the application to the
target device is required. That is, if a SCSI device is removed from the SCSI
bus, and the fibre interface is power cycled or rebooted, then the FC-to-SCSI
addressing for the remaining SCSI devices will not change. The SCSI device
can be replaced at the same address. An example of such an environment is
where hot pluggable devices may be used.

32 Choosing the Right Configuration Chapter 2

Configuration Methods

The IM can be configured over the serial port via a terminal, terminal
emulation utility or over Ethernet via a Telnet utility, Internet Web browser, or
SNMP management tool. FTP is also supported on Ethernet to upgrade
firmware revisions.

Serial

The serial port allows for configuration of device characteristics from an
attached terminal or terminal emulator. For instructions on use of the serial
interface, see Setting Up Serial Port Communications o n p a g e 5 8 .

Ethernet

The 10/100 BaseT Ethernet port must first be configured via the serial port
prior to use with either DHCP, or appropriate IP address, subnet mask, and
gateway.

Telnet

The IM is capable of holding Telnet sessions for configuration purposes (see

Configuration Using the Telnet Interface on page 72). To open a Telnet

session, the IP address of the IM and a Telnet client utility are required. The
Telnet command may be used from any open window on a HP-UX system or
from the command prompt on most Windows NT systems. Start a Telnet
session using the following steps:

1. On HP-UX‘, open a terminal window. On Windows NT, open a command prompt window.

2. At the ‘>’ prompt, enter the following command:
TELNET <IP address> where <IP address> is the IP address of the
IM. This will start a Telnet session for the IM. On Windows NT, a separate
Telnet session window will appear.

3. Enter [Admin] for the default user name and press [Enter] for the default
password. It is recommended that you change the password as soon as
possible. See Changing the Administration Password Using Telnet on
page 40 for more information.

4. Access configuration options via the menu system.

Chapter 2

5. To exit the Telnet session on HP-UX, simply close the window. On
Windows NT, you may select the disconnect option from your Telnet client
utility. In most Telnet utilities, this option is available as a menu item.

Chapter 2 Choosing the Right Configuration 33

Web Based Administrator

The IM allows any standard Internet Web browser to view and change the IM
configuration (see Configuration Using the Web Based Administrator on
page 87). Information is dynamically generated in an HTML format by the IM
so that Web browsers can access it.

To access the Web interface, enter the IP address of the IM into the address
field of a Web browser. Or, you can enter a URL using a host name defined by
the user.

To make changes to settings, use standard keyboard and mouse controls to
input information and then select the [Apply] button to send the changes to
the IM.

A password is required before any changes can be submitted. It is
recommended that you change the password using the serial or Telnet session
as soon as possible. See Changing the Administration Password Using Telnet
on page 74 for more information on setting up passwords.

Installing Fibre Channel (FC) Interface Cards

Caution Standard performance Fibre Channel interface cards are NOT

supported in the Interface Manager. The unsupported cards
have part numbers C7200-60x09 and C7200-60x16. These
can be easily identified because they have the larger 68-pin
SCSI bus connectors. Inserting these cards into the Interface
Manager will result in blowing a fuse, which will require the
replacement of the entire Interface Manager chassis.

This section covers the installation of the Fibre Channel interface cards. When
you unpack the Interface Manager, slot covers will be covering slots numbered
3 through 13.

Caution The Fibre Channel interface cards contain a laser system that is

classified as a “Class I Laser Product” under a U.S. Department
of Health and Human Services (DHHS) Radiation Performance
standard according to the Radiation Control for Health and
Safety Act of 1968 and EN60825-1(+A11) safety of laser
products. The compliance statement is located on the module.

Caution The Interface Manager contains very sensitive electrical

components. It is important to follow the proper procedure to
prevent electrostatic discharge (ESD). Use wrist-grounding straps
and anti-static mats when removing and replacing cards and
assemblies.

Failure to follow proper procedure could lead to intermittent
failures or premature hard failures.

50 Installing Fibre Channel (FC) Interface Cards Chapter 3

Fibre Channel Interface Card Installation

1. Make sure there are NO backups in progress, then turn off power to the library.

2. Remove the necessary number of slot covers from the Interface Manager.

3. To install a Fibre Channel interface card, align the top and bottom edges
of the card with the card slots (see Figure 14). Gently push the card into
the Interface Manager by placing pressure on the top AND bottom of the
card until it is flush with the Interface Manager chassis. (Pushing the card
in from the top OR bottom alone may damage the card or Interface
Manager.)

4. Tighten the thumbscrews with a flathead screwdriver.

Chapter 3 Installing Fibre Channel (FC) Interface Cards 51

Interface Manager SCSI Cable Connections

Installing SCSI Cables

Caution Turn off all devices before making SCSI connections. Failure to

turn off all power could result in damage to the devices.

Each drive’s SCSI bus should be connected to a SCSI bus on a FC interface
card in the Interface Manager. It is possible to daisy chain multiple drives to a
single port on an interface card, but this will result in significant backup
performance degradation, so daisy-chaining of drives is not covered in this
manual.

Note A set of SCSI and fibre cable labels has been provided to assist

you in the initial identification and configuration process, as well
as in troubleshooting, if a problem arises. Please label both ends
of each SCSI cable as you attach it to the FC interface card and
the drive.

For cabling diagrams see Figure 17 on page 55 for the 10/180 tape library
or Figure 18 on page 56 for the 20/700 tape library.

To begin the cabling process, do the following:

1. Shut down all peripheral SCSI devices that will be connected to the Interface Manager.

2. Locate the two matching labels in the cable label kit as follows:

a. For the HP Surestore 10/180 Tape Library:

b. For the HP Surestore 20/700 Tape Library:

52 Interface Manager SCSI Cable Connections Chapter 3

3. On the label, write the number of the drive that you will be connecting this cable to.

4. Attach one label to each end of the SCSI cable (see Figure 15). There will
be two identical labels for each FC card-to-drive connection.

5. Plug the SCSI cable into the top bus, Bus 1 on the FC interface card in slot
3 (see Figure 16 on page 54).

Figure 15 Cable Label Placement

Chapter 3

Chapter 3 Interface Manager SCSI Cable Connections 53

Figure 16 Interface Manager Bus and Slot Locations

6. Connect the other end of the SCSI cable to your chosen drive.

7. Your next connection should be labeled Slot 3 - Bus 2, then Slot 4 - Bus 1
then Slot 4 - Bus 2 and so on. Follow this process using the appropriate
labels until all FC interface cards and drive(s) have been properly labeled
and connected.

8. Install the appropriate SCSI terminators on all remaining SCSI connectors
on the drive(s). The Fibre Channel interface cards have internal
termination, so no termination is needed at the interface card end.

9. You may connect the library’s robotics controller to the last spare bus on
one of the FC interface cards, or daisy chain it with the first tape drive as
long as the library robotics controller and the tape drive are of the same
SCSI bus type (HVD to HVD, LVD to LVD).

10. Confirm that all cable ends are connected and labeled securely and that
each drive is properly terminated. The Interface Manager, in its default
configuration, provides internal termination at the end of each SCSI bus.

Caution DO NOT connect fibre or network cables until instructed to do

so, as the addressing modes and IP addresses need to be
checked prior to installation.

56 Interface Manager SCSI Cable Connections Chapter 3

Connecting the Library Controller

The library receives commands through its own SCSI bus. The library controller
may have its SCSI bus connected directly to a SCSI bus on the backup server,
or it can receive its commands through a Fibre Channel connection. If the
commands are to be transmitted through a fibre connection, then one of the
interface cards in the Interface Manager will need to have one of its SCSI
buses connected to the SCSI bus of the library.

If there is an odd number of drives in the library, there will be an unused bus to
connect the library. If there are no spare buses on the Interface Manager, daisy
chain the library’s SCSI bus onto one of the SCSI buses used by a drive. Very
little data is transmitted to the library itself, so the degradation of performance
on the drive is negligible.

Note Use the HVD to LVD converter (HP A6324A) to connect the

library’s robotics controller to an LVD SCSI bus.

In order to daisy chain the library into a SCSI bus, do the following:

1. Remove the terminator from Drive 0, Column 1.

2. Attach a SCSI cable to the connector where the terminator was removed.

3. If the Fibre Channel interface card is LVD SCSI, then a converter (HP
A6324A) from HVD to LVD is needed. Attach the other end of the cable to
the SCSI port of the library.

4. Make certain that the SCSI bus on the library is terminated.

Setting Up Serial Port Communications

Caution Before applying power to the Interface Manager, make sure the

library has completed the Initial Program Load (IPL) process, and
that all SCSI devices have been connected and powered-on and
have finished performing their self-tests. This will help determine
if device mappings are working correctly.

The DB-9 to DB-9 serial cable provided with the Interface Manager is a null­modem cable that provides a direct host to Interface Manager connection.

Attach the serial cable as shown in Figure 19.

Powering on the Interface Manager

Powering on the System

The Interface Manager is configured for most Fibre Channel installations
without intervention. The standard Interface Manager connection will be to a
Fibre Channel switch or hub.

Caution DO NOT power on the Interface Manager until all SCSI devices

have been connected and powered-on.

Note Before applying power to the Interface Manager, refer to Setting

Up Serial Port Communications on page 58 for instructions on

establishing serial communications with the Interface Manager.

1. Power-on the library.

2. Before applying power to the Interface Manager, make sure that each
SCSI device is powered-on and configured to communicate over SCSI.

3. The drives within the tape library need to be online and have valid SCSI IDs.

4. Plug the power cord into the Interface Manager.

5. Plug the other end of the power cord into the PDU, and plug the PDU into the wall outlet.

Power-On Sequence for the Interface Manager

The power-on sequence is implemented by the controller card. If the controller
card is not functioning properly, this sequence will not proceed. The Interface
Manager will take at least four minutes to access Ethernet.

The following power-on sequence will occur:

1. At power-on, the following LEDs will turn yellow:

—RMC Ready

— Controller Card Ready

60 Powering on the Interface Manager Chapter 3

— Fibre Interface Card RDY

— Fibre Interface Card LNK

2. The LED between the two SCSI bus connectors on the controller card
should turn green within a few seconds of power-on. IF this light flashes
green, it means the SCSI bus is connected to a single ended SCSI device.
This is not a failure, but an indication that there will be reduced
performance on that specific SCSI bus.

3. The Ready LED on the controller card should turn green within a few
seconds. The controller card begins to boot at this time.

4. The Fibre Channel interface card LNK LED should turn off. The FC
interface card now begins to boot when the LED turns off.

5. The Fibre Channel interface card RDY LED should turn green within two minutes:

— The RDY LED should turn solid green

— If there is no Fibre Channel connection, then the LNK LED will stay off

and the ACT light will flash.

— If there is a Fibre Channel port connected to the interface card, then

the LNK LED should become solid green.

6. The Ready LED on the RMC will flash to green then back to yellow within
another two minutes to indicate that the card is now beginning to boot.

7. If the RMC is configured to obtain its IP address from a DHCP server, the
LED on the RMC will flash yellow as it tries to get the IP address. If it is
unsuccessful, it will time out in five more minutes.

Chapter 3

8. The Ready LED on the RMC will turn green within another one minute as it boots up.

9. The RMC will be accessible via Ethernet within one minute of the Ready
LED on the RMC turning green.

The Interface Manager is now fully functional.

Chapter 3 Powering on the Interface Manager 63

Initial Configuration of the Remote Management Card (RMC)

Because the various configuration methods of the Interface Manager offer such
similar functionality, this section will describe specific configuration options
from the perspective of the serial interface only.

The Interface Manager allows the user to access many configuration settings
through the serial interface. Among these settings are:

■ Password

■ Ethernet IP addresses

All of the above settings may be changed and saved.

The main menu allows for various operations to be performed on the Interface
Manager.

The password must be set if the Web (HTTP) interface will be used, and must
be exactly 8 digits in length and may contain only the digits 1, 2, 3, or 4.

To perform any other configuration or diagnostics, the Network Access must
be configured. This must be done via the serial connection before any HTTP or
Telnet access is available.

Note The Service Diagnostics are intended for factory use only.

64 Initial Configuration of the Remote Management Card (RMC) Chapter 3

Network Access

This option allows for setting up all Ethernet network settings, including IP
address, subnet mask, IP gateway and DHCP.

Note To use the DHCP feature, a DHCP server must be operational on

the Ethernet network used by the Interface Manager. If the DHCP
feature is used when there is no DHCP server, the standard for
DHCP requires that the Interface Manager wait three minutes for
a response from a DHCP server before timing out. During this
period, the Interface Manager menus and functions will not be
accessible.

Chapter 3 Initial Configuration of the Remote Management Card (RMC) 65

4. Select [4] to toggle the DHCP setting. When DHCP is enabled, this
activates Dynamic Host Configuration Protocol and allows the Interface
Manager to be assigned a dynamic IP address from a DHCP server
located on the Ethernet network used by the Interface Manager.

5. Plug the network cable into the interface manager now.

Once the Network configuration is correctly modified, it is necessary to
reboot the RMC card before the main settings will operate.

6. Select [5] Reboot.

After the RMC finishes rebooting, the Main menu will appear. DHCP status can
be verified from the Network Access
indicated as Enabled if DHCP has been successfully activated. Note that the IP
address will also appear different than the former non-DHCP IP address.

Your DHCP server may allow you to setup a lease reservation for an IP address
by providing the server with the Ethernet MAC address of the Interface
Manager. This sets the DHCP server to always provide the same IP address to
the Interface Manager. This setup can be useful for remote management of the
Interface Manager via Telnet or the Web interface. Because the method of
setting up a lease reservation varies, depending on the DHCP server being
used, it is recommended you contact your Network Administrator for
assistance.

Note DO NOT bookmark Web interface pages with a Web browser.

Because configuration information is transmitted via URLs, there
is the possibility of the IM being configured with information
present at the time a page was book marked.

For similar reasons, it is also recommended NOT to use
navigation features of the Web browser (for instance the [BACK]
button) to navigate the Web interface.

It is recommended to navigate only using the Web page tabs
contained in the Web interface itself

Figure 27 Interface Manager Fibre Channel Address Modes

One of the advantages provided by using the HP Surestore Interface Manager
is that the addressing modes on any combination of the interface cards can be
modified at the same time.

To change the addressing mode on the interface cards, you must:

1. First change the values shown in the Future Settings fields.

2. When all of the addresses in the Future column are correct, you can
[Apply] them to all of the interface cards at once.

Make note of the settings in the Current Settings fields shown on the screen. If
these are not acceptable, you may choose to edit the Future Settings fields
one at a time, or you may use Hewlett-Packard’s recommended settings.

Hard Address Settings

If you want to use the recommended Hard address settings:

Caution Restarting an interface card during this process will stop any

data flowing through that interface card, so any backup in
progress will fail.

1. Select the [Set All Addressing Hard] button.

2. Select the [Apply] button to implement these Future settings to the
appropriate Fibre Channel interface card. Only the interface cards that
are marked as Restart, will have those settings take effect immediately.

Soft Address Settings

There are some conditions that require the interface cards to be set to Soft
addressing. This is easily done for all of the interface cards at once:

Caution Restarting an interface card during this process will stop any

data flowing through that interface card, so any backup in
progress will fail.

1. Select the [Set All Addressing Soft] button to set all of the Future Settings to soft mode.

2. Select the [Apply] button to implement those Future settings to the
appropriate Fibre Channel interface cards.

3. Only the interface cards that are marked as Restart will have those
settings take effect immediately.

Selecting Your Own Settings

If you wish to select your own settings, then each interface card needs to be
configured separately using the following sequence for each card:

Caution Restarting an interface card during this process will stop any

data flowing through that interface card, so any backup in
progress will fail.

1. Choose between Hard and Soft addressing. HP recommends that Fibre
Channel interface cards be Hard addressed, except in cases where the
switch being used is unable to use Hard addressing.

2. If you selected Hard addressing, you will need to supply an address. Each
Fibre Channel interface card in a loop must have a unique address (see

Fibre Channel Arbitrated Loop Addressing on page 29 for more details).

3. Decide if the card should be restarted when this new address setting is
applied to the selected interface card. If you check the [Restart] button,
then the interface cards will reboot when you select the [Apply] button.
Multiple interface cards will go through their restart sequence at the same
time.

4. Once you have changed the Future Settings of all of the interface cards
that you wish to change, then select the [Apply] button.

The Future Settings will be sent to all of the Fibre Channel interface cards.
Only the interface cards that have been marked as Restart will have those
settings take effect immediately.

Placing a Fibre Channel Interface Card Off-Line Using the Web Administrator

It is not necessary to remove power from the Interface Manager in order to
remove an interface card from its slot. But, it is highly recommended to inform
the firmware of your intention to do so. Placing the interface card Off-Line tells
the firmware on the RMC, on the controller card, and on the interface card that
the card is going to be removed. When it is ready for removal, the upper right
LED on the interface card will turn yellow.

Note An administrator’s password is required before any changes can

be submitted.

Note Slot number1 should contain the RMC (disregard the card type

number 2 on the card, the correct slot number is 1). Slot number
2 should contain the Controller card (disregard the card type
number 3 on the card, the correct slot number is 2). Interface
cards are in slots numbered 3 through 12.

To take a Fibre Channel interface card off-line, do the following:

1. Access the Web Administrator as described in Making Changes via the

Web Interface on page 90.

2. Select the [Operations] tab.

3. Select the [Interface Card Replacement] button.

4. Move the mouse over the image of the interface card that you wish to
place Off-line, (see Figure 28 on page 99), and click on that image.
