Installation
Before the MSA Fabric Switch 6 can communicate with Compaq-managed devices,
all devices must be properly connected and powered on.
Ethernet RJ-45 Cable
This connector is provided for management through Simple Network Management
Protocol (SNMP). By default, the MSA Fabric Switch 6 is configured to use an IP
address of 127.0.0.1. To change this IP address, use ACU-XE, a terminal, or a
terminal emulator connected to the DB-9 serial port. Refer to Chapter 2, “Initial
Configuration of the Switch,” for more detailed information on this subject.
DB-9 Serial Cable
This connector is provided for advanced configuration and management.
The MSA Fabric Switch 6 is designed to function directly out of its shipping
container with no special configuration required. However, you have the ability to
configure and monitor various aspects of the MSA Fabric Switch 6 by using
ACU-XE or CIM-XE or by connecting a terminal or terminal emulator to the serial
port. See Chapter 2, “Initial Configuration of the Switch,” for more information on
using this interface.

Overview of the Switch
Hot-Pluggable
The MSA Fabric Switch 6 is hot-pluggable. The unit can be installed and replaced
without power-cycling the MSA1000.
When adding or replacing a switch, allow sufficient time to complete the power-on
self-tests (POST) and configuration tasks before using.
To power on the unit properly:
1. Power on the MSA1000.
On power up, the switch will run several POST tests and the GSI indicator will
display changing patterns (refer to the section “Reading the Global Service
Indicator” in Chapter 4, “Troubleshooting”).
2. Power on I/O device(s).
3. Verify that the storage device(s) are visible to the host(s).
4. Start Applications.
Before the MSA Fabric Switch 6 can communicate with Compaq-managed devices,
all devices must be properly configured, connected, and powered up. See Chapter 2,
“Initial Configuration of the Switch,” for installation instructions.
1-6 Modular SAN Array Fabric Switch 6 User Guide
Initial Configuration of the Switch
This chapter details the procedures used to initially configure the MSA Fabric
Switch 6. Preliminary switch configuration includes entering the Ethernet and the
SNMP settings.
Two configuration methods are available:
• Using the text-based user interface to configure the switch
• Using the Array Configuration Utility-XE (ACU-XE) to configure the switch
2
Modular SAN Array Fabric Switch 6 User Guide 2-1
Initial Configuration of the Switch
Configuration Overview
When a switch is initially connected to a network, the network does not recognize it
and does not know its IP address. Accessing the switch and entering the Ethernet and
SNMP settings assigns the switch a location and makes it available to the network.
After the switch is accessible, additional parameters must be entered. These
secondary configuration tasks can be performed from four different user interfaces,
including the text-based user interface (text-based UI), Command Line Interface
(CLI), the ACU-XE, and the Compaq MSA Fabric Switch 6 Management Utility.
The text-based UI can be used for the initial configuration tasks and the CLI can be
accessed from this interface to perform advanced configuration tasks.
The CLI of the switch provides access to extensive management and monitoring
functions and is available directly through the serial port in the front of the switch or
remotely through the switch’s Ethernet interface using telnet. During initial set-up, it
is accessed through the text-based UI. Subsequently, the system defaults to the CLI
or the text-based UI, depending on which interface was used last. For information on
the CLI, refer to Appendix C, “Command Line Interface.”
The ACU-XE is a web-based user interface primarily used to configure the array
controllers and hard drive arrays of the MSA1000. In addition, the ACU-XE can be
used to configure the switch. Instructions for configuring the switch using the
ACU-XE are included in this chapter. For information on using the ACU-XE to
configure the storage, refer to the StorageWorks by Compaq Modular SAN Array
1000 User Guide or the Compaq Array Configuration Utility XE User Guide.
The MSA Fabric Switch 6 Management Utility provides most of the functions
available in the text-based UI and the CLI, but in a user-friendly, web-based,
graphical interface. It is accessible from Compaq Insight Manager (CIM-XE) or any
workstations equipped with a web browser. For more information, refer to
www.compaq.com/storageworks.
2-2 Modular SAN Array Fabric Switch 6 User Guide
Initial Configuration of the Switch
Using the Text-based UI to Configure the Switch
The text-based UI of the switch is available directly through the serial port in the
front of the switch. After the Ethernet settings are entered, the text-based UI can be
accessed remotely through the switch’s Ethernet interface using telnet.
following exceptions, all functions of the menu interface are available either directly
or through telnet.
• The telnet interface is available only after the MSA Switch is completely booted.
This means the results of the initialization tests are not viewable and if a reset is
issued, the telnet connection is terminated.
• Users are unable to change the password over the telnet interface.
Another difference between using the serial port interface and telnet is that when
using telnet, you can only get access to the switch after it has started
initialized its network parameters. Consequently, you

Setting the Gateway Address
Select option 4. Set gateway address in the Network Parameters menu to call up the
Set Gateway Address menu, which is shown in Figure 2-5.
The gateway is a computer or Ethernet router that connects your segment of the
Ethernet to other segments. This is also true if using telnet to communicate with the
MSA Fabric Switch 6 over the Ethernet from systems on other segments. In both of
these cases, the MSA Fabric Switch 6 will need the IP address of the gateway system
in order for it to function. Direct questions about gateways to your local network
administrator.

Accessing Management Parameters
Select option 3. Management settings in the main menu to call up the Management
Settings Menu, which is shown in Figure 2-6.
Unlike the Network Parameters menu, changes made in this menu become effective
as soon as they are made. There is no need to reset the switch.
Figure 2-6: Management Options menu
Options include:
1. Return to main menu allows the user to return to the main menu.
2. Set SNMP get community string calls up the SNMP Get Community Name
menu. This allows the user to restore the default SNMP get community name or to
enter a new SNMP get community name.
3. Set SNMP set community string calls up the SNMP Set Community Name menu.
This allows the user to restore the default SNMP set community name or to enter a
new SNMP set community name. The SNMP Set community string is the password
that any SNMP client must use to write settings to the SNMP agent on the MSA
Fabric Switch 6. This name can be any ASCII string desired. The factory default is
“private.”
4. Set SNMP trap community string calls up the SNMP Trap Community Name
menu. The SNMP Trap community string is the password that any SNMP client must
use to poll the SNMP agent on the MSA Fabric Switch 6 for SNMP traps. This name
can be any desired ASCII string. The factory default is “SNMP_trap.”
To change the SNMP Trap Community string, type the new name at the command
prompt and press the Enter key
2-10 Modular SAN Array Fabric Switch 6 User Guide
.
5. Change Password is used to enter a new password. There will be verification to
test if this has been successfully completed or not. For security reasons, the password
can only be changed through the serial port. It cannot be changed through a telnet
connection over the Ethernet.
The password can be set to null (that is, a carriage return) or an alphanumeric
password can be used with up to eight characters. The space cannot be part of the
password as it is used to separate the first and second copies of the new password.
NOTE: If the new password is forgotten, contact your network administrator. You will need the
unit’s serial number and Ethernet MAC address.
Accessing the CLI
Select option 4. Command line interface on the main menu, to call up the command
line interface. This gives the user the ability to change parameters. These parameters
should only be modified by a knowledgeable user in order to modify the MSA
Switch operational parameters, to set up policies, as well as to troubleshoot problems.
The complete Command Line Interface is outlined in Appendix C, “Command Line
Interface.”

Exiting the Text-based UI
The user can log out of the MSA Switch by selecting option 5. Logout in the main
menu. The original login prompt is redisplayed.
Resetting the Switch
Select option 6. Reset Switch in the main menu to reboot the switch. This should not
be done in a haphazard manner as all Fibre Channel connections provided by the
switch can be affected and any management data stored in the switch will be erased.
Modular SAN Array Fabric Switch 6 User Guide 2-11
Initial Configuration of the Switch
Using the Array Configuration Utility-XE (ACU-XE) to Configure the Switch
When using the ACU-XE to initially configure the switch, depending on the
controller’s settings and the current switch configuration, you will be shown various
options. The ACU-XE will prompt for information through specific screens, allowing
changes before they are saved.
In addition to accessing the ACU-XE, the switch configuration process is separated
in to two parts:
• Initial switch configuration
• Advanced switch configuration
As discussed previously, initial switch configuration includes setting the IP address,
Subnet Mask, and Default Gateway of the switch (and the redundant switch, if
installed). Until these Ethernet and SNMP parameters are entered, a Web Browser
cannot find or connect to the switch.
Advanced switch configuration includes managing and monitoring ports, setting up
zoning, and upgrading the switch firmware. Advanced configuration tasks are
performed in using the MSA Fabric Switch 6 Management Utility. A link to this
utility is provided in the ACU-XE.
NOTE: The switch configuration utility Web link to the MSA Fabric Switch 6 Management
Utility is present only if the selected controller supports this feature.
NOTE: In the following screen examples, the configuring server’s IP address is
10.100.100.14. One switch has an IP address of 10.100.100.10 and the other switch’s IP
address is 10.100.100.11.

Parameters Description
Port Speed Displays and allows you to select these values:
1 Gigabit = Port is set to operate at 1Gbps
2 Gigabit = Port is set to operate at 2Gbps
Auto = Port will determine the operating speed of the attached device
(1Gbps or 2Gbps) and operate at that speed
Port Cost (100-5000) Allow you to tune or manually configure routing.
Port cost is used by routing in the shortest path calculation. Each
switch-to-switch connection is assigned a ‘cost’ based on the shortest
path calculation. The assigned path is determined by the smallest cost.
You will only change this value if you want to tune or manually configure
the routing (to force routing to select a different path). However, you
may wish to modify the cost value if you know the distance on one port
is much greater than on another port or if you know the port speeds are
different (1Gb vs. 2Gb).
Port Heartbeat (5-50) Allows you to manually adjust the number of times a heartbeat signal is
missed before routing decides the switch is not longer present. Port
heartbeat is used by routing to verify that a switch is still present.
Port Reset Use the scroll-bar at the right side of the panel to bring this option into
view. Port Reset allows you to reset the port to the previously set
parameters. Click the Reset Port to return to the previous port settings.

Parameter Description
Switch Role Displays whether switch is configured as the Principal switch or a Subordinate
switch in the Fabric.
Name Displays the system-generated switch name:
• Switch installed in slot 1: MSA1000 name-switch1
• Switch installed in slot 2: MSA1000 name-switch2
Priority (1-255) This parameter allows you to determine the priority that this switch will have
compared to other devices if it requests Fabric resources at the same time as
other devices. The variable is used during the SW-2 principal switch selection
process. Any number between 1 and 255 can be used for this setting. A lower
number results in a higher priority for the switch. The switch with the lowest
priority number will become the principal switch. If two switches have the same
“lowest priority number”, then the switch with the lowest WWN number will
become the principal switch.
A priority 1 forces the switch to be principal; a priority 255 will never allow the
switch to be principal switch. Priority 2 is reserved for the current elected
principal switch. The principal switch will change its priority to 2 if its priority is
greater than 2.
Desired Domain
(1-239)
Actual Domain Displays the current domain.
Address
Translation
Any number between 1 and 239. For inter operability, each switch in a Fabric
must have a different domain number. You can specify the desired domain.
However, the actual domain that is set may be different (for example, if the
domain is already in use). This domain number is used during SW-2 principal
switch selection.
Address translation allows you to address devices with private addresses
through the Fabric. The port must be private for this to function. Choose the
correct radio button to turn address translation on or off. This is limited to private
targets.

Choosing Off disables Force In Order delivery and allows out-of-order
delivery. Note that some legacy devices cannot handle out-of-order
delivery and will require that this feature be enabled on all switches.
This is the delay time for Force In Order Delivery (if enabled). It
specifies the delay time before rerouting traffic to an alternative trunk.
The minimum delay time is 1 second; the maximum delay is 60
seconds. Set this parameter to greater than the E_D_TOV time of the
legacy device that requires in order delivery.

MSA Fabric Switch 6 Management Utility
Polling Rate This setting allows you to specify the rate for detecting the changes of devices in
the network or changes in the device environment status. Valid values are 13600(sec).
Timeout When the Fabric Management Utility issues a request to a managed device, if the
device fails to respond, it waits for a specified number of milliseconds and then
retries its request. This parameter sets the amount of time that the switch utility
waits before it retries its request. Valid values are 500-5000 (ms).
The timeout for each retry is increased exponentially. For example, if the timeout
value is set to 5000 ms and retry is set to 2:
• The initial attempt will time out in 5000 ms.
• The first retry will time out in 10000 ms.
• The second retry will time out in 20000 ms.
Compaq recommends that you set the retry count low if the timeout value is high.

Setting up Zoning
Zoning is a function of the MSA Fabric Switch 6 that allows you to create isolated
Fibre Channel networks with a limited number of connected devices. By limiting the
number of devices in a zone, you can obtain more robust performance and enhance
access protection.
Zoning is compliant with the following standards:
• FC-SW-2
• FC-GS3
• FC-MI
3-50 Modular SAN Array Fabric Switch 6 User Guide
This section describes the zoning functions supported by the MSA Fabric Switch 6. It
describes zoning at the individual switch and describes how the
functions are used to support zoning across a Fabric.
Zoning Elements
Before setting up zoning, you must understand the following zoning elements:
• Zone Members
• Zones
• Zone Sets
CAUTION: Never add a zoned switch to an established fabric that has no zoning. If
a switch configured with zoning is added to a fabric that has no configured zoning,
the fabric’s HBAs and targets will no longer be able to communicate and the traffic in
the fabric will be disrupted. For best results, only add a switch configured with zoning
to a fabric configured with the same zoning configuration.
Zone Members
MSA Fabric Switch 6 Management Utility
merge command
Zone members are Fibre Channel edge devices that are identified by their World
Wide Port Name (WWPN). Any device that you want to include in a zone must be
identified as a zone member. While internally the zone members are tracked by their
WWPN, you can create a Zone Member Name that acts as an alias for the device.
This makes it easier to identify the devices during configuration and operation. The
following are examples of Fibre Channel devices that can be named as zone
members:
• Servers
• Raid systems
• Disk drives
• Tape libraries
IMPORTANT: The World Wide Node Name (WWNN) of the Fibre Channel device cannot be
used to create a zone member. WWNN-bases zoning is expressly prohibited in the FC-MI
standard. Use World Wide Port Name (WWPN) to create a zone member.
Modular SAN Array Fabric Switch 6 User Guide 3-51
MSA Fabric Switch 6 Management Utility
Zones
Zones are logical entities that represent groupings of zone members. Each zone must
be assigned a unique zone name when it is defined.
Zone Sets
Zone sets are logical entities that represent groupings of zones. They define a zoning
configuration. Each zone set is assigned a unique zone set name when it is defined.
The MSA Fabric Switch 6 allows storing of multiple zone sets. However, only one of
these zone sets can be active at a time. The other zone sets can be used as backup,
trials, or other user-defined configurations.
Naming Rules for Zone Members, Zones, and Zone Sets
Zone member, zone, and zone set names must follow these rules:
• Names must be between 1 and 64 characters long
• Characters used in names must be 7 bit ASCII characters
• The first character of a name must be a letter (a-z) and can be either upper case or
lower case
• Other characters of the name (any characters besides the first character) can be a
letter (a-z, either upper or lower case), a number (0-9), or a symbol ($ - ^ _).
• No spaces are allowed in the name

Zoning Limitations for Zone Members, Zones, and Zone Sets
There are zoning limitations for individual switches and fabrics. See Table 3-17 for
maximum limitations.

Two Ways to Display Zoning
The MSA Fabric Switch 6 Management Utility allows you to display zoning in two
ways:
• Merged zones
• Local zones
To toggle between the Merged Zones display and the Local Zones display, expand
the Zoning View drop-down list in the Zoning Configuration screen.
Merged Zones
Use the Merged Zones display when you are interested in viewing information for
zones merged with other switches on the Fabric.
This view is read-only and cannot be edited. The Merged Zones view is a
Fabric-wide display showing the merged zones with other switches on the fabric.
NOTE: Because only one Zone Set can be active across the entire Fabric, only the Active
Zone Set is shown.
Modular SAN Array Fabric Switch 6 User Guide 3-53

Local Zones
Use the Local Zones display when you are interested in viewing, creating, or editing
zone sets, zones, and zone members for the switch presently being monitored.
This view is a read/write single-switch display showing the zone sets, zones, and
zone members for that switch. You can create, edit and remove zone sets, zones, and
zone members using the Local Zones view.

Troubleshooting the MSA Fabric Switch 6
If there is a problem accessing a device connected to the MSA Fabric Switch 6, the
source of the problem can be with the device, the switch, the host, or any of the
connections between the host and device. Follow the steps outlined below to
investigate the problem. The following is a description of possible symptoms:
1. Check the Global Status Indicator for power. The unit may not be plugged into
the Modular SAN Array 1000 correctly.
2. Inspect the switch fault indicators for apparent problems. If the fault indicators
are on, the switch may be faulty or the temperature may be out of defined limits.
3. Inspect the cabling between the switch and attached Fibre Channel devices.
Check for loose, dirty, broken, or bent cabling and connectors. If a Compaqsupported Small Form Factor Pluggable transceiver (SFP) is in use, check that it
is properly inserted and that the cable is properly seated.
4. Check the port status indicators.
Reading the Global Status Indicator
The indicators provide information about the status of the switch. This should be
used as the first stage in troubleshooting. If either the serial or the Ethernet link to the
switch is running, use the appropriate Command Line Interface command (See
Appendix C, “Command Line Interface,” for the appropriate command). The Global
Status Indicator indicators can be interpreted by reviewing Table 4-1.
