numbers located on the switch. Each serial number provides specific logistical
information, identifying the device’s manufacturing location.

Installing the SAN Switch 2/32

28 SAN Switch 2/32 Installation Guide

Installation and Safety Guidelines

Read the following sections for installation guidelines. Install the SAN Switch
2/32 in one of the following ways:

■ As a stand-alone unit on a flat surface.

■ In an Electronics Industries Association (EIA) cabinet (like the HP 9000

Series Rack), using the Slide Rack Mount Kit provided with the switch. See
Slide Rack Mount Kit contents outlined in Tab le 3.

■ In an HP System/e rack.

Selecting an Operating Location

To ensure correct operation of the switch, the location where the switch is in use
must meet the following requirements:

■ Adequate supply circuit, line fusing, and wire size, as specified by the

electrical rating on the switch nameplate.

■ An air flow of at least 300 cubic feet per minute, available in the immediate

vicinity of the switch.

■ If installing the switch in the HP 9000 Series, or comparable EIA rack:

— All equipment installed in the rack should have a reliable branch circuit

ground connection, and should not rely on a connection to a branch
circuit, such as a power strip.

— The rack should be balanced and the installed equipment should be within

the rack’s weight limits. Ensure the rack is mechanically secured to insure
stability in the event of an earthquake.

Cooling Requirements

Cooling air is drawn into the switch chassis by the fans mounted on the rear of the
chassis. The air is expelled through vents in the front (port side) of the chassis,
next to the HP logo. HP recommends installing the switch so that air intake and
exhaust for all components in the rack is flowing in the same front-to-back
direction.

Note: HP highly recommends mounting the switch in a cabinet or rack so that the fans

reside in the front of the cabinet, and the ports (cables) reside in the rear of the cabinet.

Installing the SAN Switch 2/32

29SAN Switch 2/32 Installation Guide

Follow these guidelines to ensure proper air flow, and prevent component
overheating:

■ To ensure adequate cooling, install the switch with the non-port side, which

contains the air intake vents, facing the cool-air aisle.

■ Verify a minimum of 47 cubic feet/minute (79.8 cubic meters/hour) of air

flow is available to the air intake vents on the non-port side of the switch.

■ Verify that the ambient air temperature does not exceed 40° Celsius (104°

Fahrenheit) while the switch is operating.

Caution: Do not block air vents. The switch uses ambient air for cooling.

Power Requirements

Two AC power cords connect to the switch on either side of the rear panel. The
AC power source must meet these requirements:

■ Primary AC Input 100–240 VAC (switch auto-senses input voltage) 47–63 Hz

■ Correctly wired primary outlet, with circuit protected by a circuit breaker and

grounded in accordance with local electrical codes

■ Adequate supply circuit, line fusing, and wire size, as specified by the

electrical rating on the switch nameplate

■ Voltage capability of 85–264 VAC

■ Input voltage frequency of 47–63 Hz

■ Power capability of 75 W maximum

The switch has a universal power supply capable of functioning worldwide
without voltage jumpers or switches. The power supply is auto ranging in terms of
accommodating input voltages and line frequencies.

Installing the SAN Switch 2/32

30 SAN Switch 2/32 Installation Guide

Setting Up the Switch as a Stand-alone Unit

Use these procedures for setting up the switch as a stand-alone unit. The following
items are required for this setup:

■ SAN Switch 2/32

■ AC power cords and cables supplied with the switch

■ Rubber mounting feet supplied with the switch

1. Place the SAN Switch 2/32 on a flat, sturdy surface like a table or lab bench.

2. Apply the rubber feet as follows:
a. Clean the four depressions that are at each corner of the bottom of the

switch to ensure they are free of dust.

b. Place a rubber foot in each depression, with the adhesive side against the

chassis, and press into place.

Caution: Installing the rubber feet on the switch is recommended to help

prevent the switch from accidentally sliding off the table or bench.

3. Connect the power cables to the SAN Switch 2/32 power connectors and to a
power outlet. Ensure the power cable is routed so that it is not exposed to
stress.

4. Turn on the power to the switch (flip the AC switch to “1”). The switch
automatically runs a Power On Self-Test (POST).

Caution: Do not connect the switch to the network until the IP address is

correctly set. For instructions on how to set the IP address, see “Configuring

SAN Switch 2/32 Network Addressing,” later in this chapter.

Installing the SAN Switch 2/32

31SAN Switch 2/32 Installation Guide

Installing the SAN Switch 2/32 in an HP Series 9000
or EIA Cabinet

Read the following sections for complete installation instructions. Before you
begin, obtain the following tools:

■ #2 Phillips screwdriver, with torque capability

■ Torx screwdriver

■ Slotted blade screwdriver, 1/4 inch, with torque capability

Rack Mount Checklist

Verify that the rack and the area around the rack meets the following
requirements:

■ The cabinet must be a standard EIA cabinet.

■ Plan a cabinet space that is 1.5 rack units high (2.6 inches; 6.7 cm), 19 inches

(48.3 cm) wide, and at least 23 inches (68.6 cm) deep.

■ Ground all equipment in the cabinet through a reliable branch circuit

connection, and maintain ground at all times. Do not rely on a secondary
connection to a branch circuit, such as a power strip.

■ Ensure that airflow and temperature requirements are met on an ongoing

basis, particularly if the switch is installed in a closed or multi-rack assembly.

■ Verify that the additional weight of the switch does not exceed the cabinet’s

weight limits or unbalance the cabinet in any way.

■ Secure the cabinet to insure stability in case of unexpected movement.

Note: This procedure is written with the assumption that the non-port side of the switch,

which contains the air intake vents, is installed facing the cool-air aisle.

Installing the SAN Switch 2/32

32 SAN Switch 2/32 Installation Guide

Installing the Slide Rail Assemblies to the Switch

The SAN Switch 2/32 Rack Mount Kit consists of two slide rail assemblies
consisting of an inner slide rail attached to an outer slide rail. Read the following
sections for complete instructions on first separating, then installing the Slide Rail
Assemblies.

Separating the Inner Slide Rail Assembly from the
Outer Slide Rail Assembly

Separate the two inner (smaller) slide rails from the two outer (larger) slide rails as
follows.

1. Holding one slide rail assembly horizontally, pull the inner slide rails out of
the outer slide rail until the lock release lever engages.

2. Press the lock release lever located on the inner slide rails. The inner slide rail
separates from the outer slide rail.

3. Repeat steps 1 and 2 to separate the second slide rail assembly.

4. Put the outer slide rails aside. Follow the steps in the next section, “Attaching

the Inner Slide Rails to the Switch.”

Attaching the Inner Slide Rails to the Switch

Use the following steps to secure each inner slide rail to the switch chassis.

Caution: It is important to install the inner slide rails using the Phillips head,

8-32 x 3/16 inch screws supplied in the Rack Mount Kit. Installing screws
longer than 3/16 inch can damage the switch.

1. Position the inner slide rails with the flat side against the switch, oriented in
one of the following two ways:

Installing the SAN Switch 2/32

33SAN Switch 2/32 Installation Guide

Caution: HP recommends installing the SAN Switch 2/32 so that the port side

of the switch slides out the rear of the rack (as described in step 1a below). In
this way, the switch faces the aisle where exhaust air is released. Air intake
and exhaust for all components in the rack should flow in the same direction.

a. To allow the port side of the switch to slide out the rear of the rack:

Orient the inner slide rail with the end containing the lock release lever
towards the power supply end of the switch.

b. To allow the power supply side of the switch to slide out the front of the

rack:
Orient the inner slide rail with the end containing the lock release lever
towards the port end of the switch.

2. Locate three Phillips head, 8-32 x 3/16 inch screws provided in the Rack
Mount Kit. Secure the inner slide rail to the switch, see Figure 4.

3. Tighten the screws and torque to 15 inch-pounds.

Attaching the Rear or Front Rack Mount Brackets

The Rack Mount Kit supplied with the SAN Switch 2/32 contains two rear rack
mount brackets and two front rack mount brackets. Install these rack mount
brackets to prevent the switch from accidentally sliding out of the rack, as follows.

Caution: HP recommends installing the SAN Switch 2/32 so that the port side

of the switch slides out the rear of the rack. (For example, the switch should
face the aisle where exhaust air is released. Air intake and exhaust for all
components in the rack should flow in the same direction.)

For Rear Rack Access

Use these steps to attach the rear rack mount brackets to the switch. The rear rack
mount brackets act as “stops” to prevent the switch from sliding out the rear of the
rack. Use these steps if you installed the inner slide rails to the switch using the
procedure outlined in “Attaching the Inner Slide Rails to the Switch,” step 1a.

1. Align the right rack mount bracket with the two screw holes at the port end of
the switch.

2. Locate two Phillips head 8-32 x 3/16 inch screws, contained in the Rack

preinstalled at the end of each outer slide rail; see Figure 6. The L-brackets are
necessary to attach the outer rails to the rack.

1. Determine the appropriate placement for the switch inside the rack. The HP
9000 Series Rack’s rails are divided into Units (Us). Each U is marked with a
small, round hole and three square openings for mounting equipment.

Note: The SAN Switch 2/32 requires 1.5 Units of rack space.

2. Locate the small, round marker hole on the rack’s rails, which coincides with
the location selected in step 1. Each marker hole delineates the beginning of
one U.

3. Insert one square alignment washer on each of the

eight 10-32 x 3/8 inch Phillips

head screws.

Note: The square alignment washers are mandatory for proper switch alignment.

4. Adjust the outer slide rail’s length to fit the length of the rack.

5. Position one of the outer slide rails in the rack, as described below:
a. To allow the switch’s port end to slide out the back of the rack, orient with

the closed end of the outer slide rail towards the front of the rack.

b. To allow the power supply end to slide out the front of the rack, orient the

closed end of the outer slide rail towards the back of the rack.

6. Holding the outer slide rail in place, insert one 3-hole bar nut in between the
rack’s rail and the L-bracket at the end of the outer slide rail, Figure 6.

Note: Position the square alignment washers onto the Phillips head 10-32 x 3/8 inch

screws, as described in step 3. The square alignment washers are mandatory for
proper switch alignment.

Positioning the Switch in the HP 9000 Series Rack

Follow these steps to install the switch in the rack.

Note: If installing more than one SAN Switch 2/32 directly on top of one another (in a

3U space), you must mount the slide rails attached to the switch using the set of holes
on the top of the switch, and the bottom using the set of holes on the bottom of the
switch.

1. Depending on the type of install (front or rear access), slide the outer slide
rails all the way toward the front or back of the rack.

2. Carefully lift the switch into the rear of the rack, inserting the inner slide rails
(attached to the switch) into the outer slide rails (attached to the rack).

3. Slide the switch into the rack; see Figure 7.

Power On Self-Test

Each time the switch is powered on, rebooted, or reset, the switch automatically
runs POST. During POST, the port status LEDs flash, verifying that the switch is
operating properly. POST completes in approximately six minutes, with total boot
time approximately seven minutes.

POST runs through the following test cycles:

■ Preliminary POST diagnostics

■ Initialization of operating system

■ Initialization of hardware

■ Diagnostic tests are run on a number of functions, including circuitry, port

functionality, memory, parity, statistics counters, and serialization

If the switch prompt does not display when POST completes, POST was
unsuccessful. Contact your authorized HP switch supplier for more information.

To determine whether POST completed without errors, verify that all LEDs return
to a normal state after POST is complete. If one or more LEDs do not return to a
normal state (and this is not due to the switch being set to beacon), see
“Interpreting LED Activity,” in Chapter 3.

Note: For more information about beaconing, refer to the

HP StorageWorks Fabric

OS Procedures Version 3.0.x/4.0.x User Guide

.

Checking POST Results

Check the success/fail results of the diagnostic tests run during POST via LED
activity, the error log, or CLI using the errShow command. For more
information about error messages, refer to the HP StorageWorks

Fabric OS

Version 3.0.x/4.0.x Reference Guide.

Core Switch PID Format Summary

A Core PID format is one of several addressing formats used in Fibre Channel.
The parameter is used by the routing and zoning services in Fibre Channel fabrics
to identify ports in the network.

The PID format is analogous to specifying the physical switch and port that a
device is attached to in data networks. It is not analogous to an IP address. PIDs
are assigned by a Fibre Channel switch when a device logs into the fabric. An
example PID might look like this: 011F00.

Many scenarios cause a device to receive a new PID. For example, unplugging the
device from one port and plugging it into a different port will cause this. (This
might happen when cabling around a bad port, or when moving equipment
around.) Another example is changing the domain ID of a switch, which might be
necessary when merging fabrics, or changing compatibility mode settings.

Note: All switches running Fabric OS version 4.0.x or higher are shipped with the

Core Switch PID Format enabled, so it is not necessary to change the Core Switch PID
format on these switches. For example, the HP StorageWorks SAN Switch 2/32 and HP
StorageWorks Core Switch 2/64 always use Core Switch PID format 1. This parameter
is always 1 and cannot be changed.

Important Information on Checking the Core Switch PID Format

Updating the Core Switch PID Format is necessary when upgrading an existing
SAN to support larger port-count switches. When a switch with more than 16
ports is introduced into an existing fabric, this parameter needs to be set on all
switches in the fabric.

For example, all SAN Switch 2/32 units ship with the Core Switch PID format set
to 1. Before connecting to the SAN, you must verify that the Core Switch PID
formats of all switches already running in the SAN are also set to 1.

Note: If the Core PID format is set to 0 in switches already running in the SAN, you

must follow the procedures in Appendix B, “Updating the Core Switch PID Format” to
change the parameter to 1. If the Core Switch PID format is not changed to 1 to match
the SAN Switch 2/32’s value, then the switches residing in the SAN will fail to
communicate with one another.

Installing the SAN Switch 2/32

53SAN Switch 2/32 Installation Guide

For detailed recommendations and instructions on updating the Core Switch PID,
please refer to Appendix B in this guide, “Updating the Core Switch PID Format.”

Optional Configuration Settings

The following sections describe how to modify domain IDs and status policies.

Modifying Domain IDs

Optional. Modify the domain IDs, if desired, as follows.

Note: The default domain ID is 1. If the default domain ID is already in use when the

switch is connected to the fabric, the domain ID for the new switch is automatically reset
to a unique value. The domain IDs that are currently in use can be determined using the
telnet command fabricShow.

1. Disable the switch by entering the following:

switchDisable

2. Enter the following:

configure

3. Enter y after the Fabric parameters prompt.

Fabric parameters (y, n)

4. Enter a unique domain ID (such as the domain ID used by the previous
switch, if still available).

Domain: (1..239) [1] 3

5. Complete the remaining prompts (or press CTRL+D to accept the remaining
settings without completing all the prompts).

6. Re-enable the switch by entering the following:

switchEnable

Specifying Custom Status Policies

Optional If desired, specify any custom status policies for the fabric as follows.

1. Enter the following at the prompt.

switchStatusPolicySet

2. Specify the desired status policies. To completely deactivate the alarm for a
particular condition, enter 0 at the prompt for that condition.

Installing the SAN Switch 2/32

55SAN Switch 2/32 Installation Guide

Note: Configure each port to match the topology of each host or target before

connecting to the device. The default port configuration is fabric, not private loop. The
switch does not auto-sense topology.

Installing the SAN Switch 2/32

56 SAN Switch 2/32 Installation Guide

Connecting the SAN Switch 2/32 to the Fabric

Use these steps to connect the SFPs and cables to SAN Switch 2/32 ports as
required.

Note: The ports and cables used in trunking groups must meet specific requirements.

For a list of these requirements, refer to the

HP StorageWorks ISL Trunking Version

3.0.x/4.0.x User Guide

.

1. Remove the shipping plug from the appropriate ports.

2. Position the SFP so that the key (the tab near the cable-end of the SFP) is on
top.

3. Insert the SFP into the port until it is firmly seated and the latching
mechanism clicks.

Note: The SFP is keyed so that it can only be inserted with the correct orientation into

the port. If the SFP does not slide in easily, check the orientation.

4. Connect the cables to the SFPs as appropriate to the fabric topology, by
positioning each cable so that the key (the ridge on one side of the cable
connector) is aligned with the slot in the SFP; see Figure 15.

Installing the SAN Switch 2/32

57SAN Switch 2/32 Installation Guide

Figure 15: Inserting a cable into an SFP

Note: The cable is keyed so that it can only be inserted correctly into the SFP. If the

cable does not slide in easily, check the orientation.

Verifying Operation

After making the appropriate connections, as outlined in this chapter, use these
steps to verify that the switch is running properly.

1. Access your browser.

2. At the URL address window, type

http://your switch IP address.

3. If connected properly, the name of your switch appears (in green) at the
prompt, indicating Healthy/OK.

Note: Backing up the configuration is strongly recommended. This ensures that a

complete configuration is available if required for a replacement switch. For instructions
on how to back up the configuration, refer to Chapter 4, “Backing Up Configuration
Data and Upgrading Firmware.” Or, for more detailed information and commands,
refer to the

HP StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide.

Installing Multiple Switches into an Existing SAN

Use these steps to set up more than one SAN Switch 2/32 in an existing SAN.

1. Connect the appropriate components as outlined in the installation section of
this chapter.

2. Connect the power cord to the AC connector on the switch. The switch
performs POST.

If a malfunction occurs during POST, error messages are written to the switch
error log and can be viewed by a telnet or terminal session when the POST
session completes.

If the malfunction prohibits the switch from completing the boot process (fatal
error), the switch stops the boot process. If the switch does not fully boot, the
switch prompt will not be displayed when the Serial port is connected.

3. Connect the Serial cable, provided in the package contents, between a host
computer and the Serial port of the switch. See “Setting Network Addresses
via a Serial Connection,” earlier in this chapter, to make a Serial connection
through a workstation and to set the IP address.

4. Set the switch Domain Address using the configure command to the next
unused domain in the SAN. The default domain setting is 1.

Note: If a switch boot failure occurs, the switch must be taken offline for repair or

replacement. Contact your HP Technical Support for assistance.

5. Power off the new switch and connect one Fibre Channel cable from the SAN
to the new switch.

59SAN Switch 2/32 Installation Guide

Recommendations for Cable Management

HP recommends following these cable management guidelines:

■ Plan cable management before installing the switch in a rack.

■ Leave at least one meter of slack for each port cable (this provides room to

remove and replace the switch).

■ If using ISL Trunking:

— Group cables by trunking groups.
— The cables used in trunking groups must meet specific requirements. For

a list of these requirements, refer to the HP StorageWorks ISL Trunking
Version 3.0.x/4.0.x User Guide.

■ Label the fiber optic cables and record the devices to which they are

connected.

■ Keep LEDs visible by routing port cables and other cables directly

downwards or otherwise away from the LEDs.

■ Do not use tie wraps on fiber optic cables, because they are easily

overtightened and can damage the optic fibers.

Note: The minimum bend radius for a 50-micron cable is 2 inches under full tensile

load, and 1.2 inches with no tensile load.

Setting the Switch Date and Time

All switches maintain current date and time in non-volatile memory. Date and
time are used for logging events. Switch operation does not depend on the date
and time; a switch with an incorrect date and time value still functions properly.

Uses these steps to set the date and time of a switch.

1. Login to the switch as the admin user.

2. At the command line, enter the following command:

date "MMDDhhmmYY"

where:

— MM is the month, valid values are 01–12.
— DD is the date, valid values are 01–31.
— hh is the hour, valid values are 00–23.
— mm is minutes, valid values are 00–59.
— YY is the year, valid values are 00–99.

Note: Year values greater than 69 are interpreted as 1970-1999; year values less than

70 are interpreted as 2000-2069. The date function does not support daylight saving
time or time zones.

SAN Switch 2/32 Diagnostics

Read the following sections for information on using POST and diagnostic tests.

Interpreting POST Results

Each time the switch is powered on or reset, the switch automatically performs
POST, a one-minute system check during which the port status LEDs flash
different colors.

To determine whether POST completed without errors, verify that all LEDs return
to a normal state after POST is complete. If one or more LEDs do not return to a
normal state, and this is not due to the switch being set to beacon, refer to the HP
StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide.

Note: If the switch prompt does not display when POST completes, POST was not

successfully completed and the switch should be returned to your switch supplier for
repair.

Any errors detected during POST are written to the system log, accessible through
the errShow command. For more information about error messages, refer to the
HP StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide.

Additional Diagnostic Tests

The SAN Switch 2/32 uses diagnostic tests to help troubleshoot hardware and
firmware. The diagnostic tests provided on the switch include tests of internal
connections and circuitry, fixed media, and any SFP modules and fiber optic
cables in use. The tests are implemented by command, either through a telnet
session or through a terminal set up for a Serial connection to the switch. Some
tests require the ports to be connected by external cables, to allow diagnostics to
verify the serializer/deserializer interface, and to verify the attached SFP and
cable.

All diagnostic tests are run at link speeds of both 1 Gbps and 2 Gbps. For
information about the specific diagnostic tests and how to run them, refer to the
HP StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide.

Managing the SAN Switch 2/32

75SAN Switch 2/32 Installation Guide

Note: The transmit and receive speed of the links may be temporarily locked to a

specific speed during diagnostic testing.

Field Replaceable Units

You can replace the power supplies, fan assemblies, and motherboard in the field
without the use of special tools. The power supplies and fan assemblies are keyed
to ensure correct orientation during installation. Replacement instructions are
provided with all replacement units ordered.

Note: The SAN Switch 2/32 uses two AC power cords. To remove all power from the

switch, disconnect both power cords before servicing.

.

Use these steps to upload a backup copy of the configuration settings to a host
computer.

1. Verify that the RSHD service (on a UNIX machine) or the FTP service (on a
Windows or UNIX machine) is running on the host workstation.

2. Login to the switch as the admin user.

3. At the command line enter the following command:

configUpload "hostIPaddr", "user",
"path_filename","password"

For example, hostIPaddr is the IP address of the host computer, user is the User
ID used to log into this computer, path_filename is the path location and filename
of the configuration file, and password is the password for the user ID specified.

If only configupload is entered, the system will prompt you for each
parameter, as follows:

Example:

switch:admin> configupload
Server Name or IP Address [host]: 123.45.678.901

Updating the Core Switch PID
Format

This Appendix provides detailed information for changing the Core Switch PID
format. The SAN Switch 2/32 units ship with the Core Switch PID format set to 1.
Before connecting to the SAN, you must verify that the Core Switch PID formats
of all switches already running in the SAN are also set to 1. If the Core Switch
PID format is not changed to 1 to match the SAN Switch 2/32’s value, then the
switches residing in the SAN will fail to communicate with one another.

Note: All switches running Fabric OS version 4.0.x or higher are shipped with the

Core Switch PID Format enabled, so it is not necessary to change the Core Switch PID
format on these switches. For example, the HP StorageWorks SAN Switch 2/32 and HP
StorageWorks Core Switch 2/64 always use Core Switch PID format 1. This parameter
is always 1 and cannot be changed.

Updating the Core Switch PID Format

92 SAN Switch 2/32 Installation Guide

HP Recommendations on Changing the Core
Switch PID Format

Proactively setting the core PID format on all new fabrics before they enter
production will prevent the need to update those fabrics in the future. This is
strongly recommended as a step in the deployment of all new fabrics. There is no
difference in the behavior of a fabric with either PID format; changing to the new
format during deployment will merely save administrative effort later on.

HP strongly recommends against using drivers that bind by PID. There are several
routine maintenance procedures which may result in a device receiving a new
PID; the core PID format update is just one example of such a procedure.
Examples include but are not limited to:

■ Changing “Compatibility Mode” settings.

■ Changing switch domain IDs.

■ Merging fabrics.

■ Relocating devices to new ports or new switches (that is, for Add, Move,

Change type operations.

■ Using hot spare switch ports to deal with failures.

■ In every case where devices bind by PID, any such procedure will become

difficult or impossible to execute without downtime.

Note: HP always recommends redundant fabrics and multi-pathing software for

uptime-sensitive environments. If a redundant SAN architecture is in place, the Core PID
update can take place without application downtime. To ensure maximum ease of
administration, this parameter can and should be proactively set on a fabric before it
ever enters production, whether or not an upgrade to larger switches is planned.

Updating the Core Switch PID Format

93SAN Switch 2/32 Installation Guide

How to Check the Current Core PID Setting for Switches Running
Firmware Lower than V4.0.0

To view a switch’s current Core Switch PID format, connect directly to a switch in
your SAN and complete the following steps via a telnet session or the Serial cable
supplied.

1. Type configShow and press Enter.

2. About 15 lines down (press Enter to display more information on the page),

locate the following line:

fabric.ops.mode.pidFormat: 0

Note: The [0] value shown above indicates the Core Switch PID parameter is not set on

this particular switch, and the switch will not use the Core Switch PID format addressing.

If necessary, proceed to the next section for detailed procedures on changing the
Core Switch PID format to 1.

Updating the Core Switch PID Format Online

In order for the switches already running in the SAN to interoperate properly with
the SAN Switch 2/32, all of them must use a Core Switch PID format setting of 1.
If the Core Switch PID format assigned to switches already running in the SAN is
0, then you must use these steps to update the value to 1.

Note: The online update process is only intended for use in uptime-critical dual-fabric

environments, with multi-pathing software. If dual-fabrics are not in place, there are a
number of routine maintenance scenarios which require scheduled downtime, the core
PID migration process being only one example. High-uptime environments should
always use a redundant fabric SAN architecture.

Complete these steps to update the Core Switch PID format while the SAN is
running online.

1. Back up all data. Verify backups.

2. If the multi-pathing software cannot automatically switch over between
fabrics seamlessly enough for the users of the SAN, use the software’s
administrative tools to manually disassociate, or mark offline all storage

Updating the Core Switch PID Format

94 SAN Switch 2/32 Installation Guide

devices on the first fabric to be updated. (This is the best practice in cases
where any doubt exists about the multi-pathing software’s behavior, but is
more labor intensive.)

3. Verify that I/O continues over the other fabric.

4. Disable all switches one at a time in the fabric to be updated.

5. Verify that I/O continues over the other fabric after each switch disable.

6. Change the PID format on each switch in the fabric, as follows:
a. Telnet into each switch in the fabric.
b. Type switchDisable, and press Enter.
c. Type configure and press Enter.
d. Type y at the Fabric parameters prompt, (yes, y, no, n): [no] y.
e. To view the Core Switch PID setting, press Enter until you reach the

Core Switch PID format line, similar to the following.

Core Switch PID Format: (0..1) [0]

Note: The [0] value shown above indicates the Core Switch PID parameter set on this

particular switch.

f. Type 1 to update the Core Switch PID format.
g. Continue to press Enter until you have completed the configure section

and have returned to the admin prompt.

7. One at a time, re-enable the switches in the updated fabric. In a core/edge
network, enable the core switches first.

8. Once the fabric has re-converged, type cfgEnable myZoningCfg (where
myZoningCfg is the name of your zone configuration). Press Enter to
update zoning.

Note: This does not change the definition of zones in the fabric, but causes the lowest

tables in the zoning database to update with the new Core Switch PID format.

9. Repeat steps 3 through 6 for all fabrics in the SAN.

Updating the Core Switch PID Format

95SAN Switch 2/32 Installation Guide

10. For any devices manually bound by PID, update their bindings. This may
involve changing them to the new PIDs, or may (preferably) involve changing
to WWN binding.

11. For any devices automatically bound by PID, two options exist:
a. Execute a custom procedure to rebuild its device tree online. Examples

are given in this appendix.

b. Reboot the device to rebuild the device tree. Some operating systems

require a special command to do this. E.g. boot –r in Solaris.

12. For devices that do not bind by PID, or have had their PID binding updated,
mark online or re-associate the disk devices with the multi-pathing software
and resume I/O over the updated fabric.

Updating the Core Switch PID Format Offline

Complete these steps to update the Core Switch PID format while the SAN is
running offline.

1. Back up all data. Verify backups.

2. Shut down all hosts and storage devices attached to the SAN.

3. Disable all switches in the fabric requiring the update.

4. Change the PID format on each switch in the fabric, as follows.
a. Telnet into each switch in the fabric.
b. Type switchDisable, and press Enter.
c. Type configure and press Enter.
d. Type y at the Fabric parameters prompt, (yes, y, no, n): [no] y.
e. To view the Core Switch PID setting, press Enter until you reach the

Core Switch PID format line, similar to the following.

Core Switch PID Format: (0..1) [0]

Note: The [0] value shown above indicates the Core Switch PID parameter set on this

particular switch.

f. Type 1 to update the Core Switch PID format.
g. Continue to press Enter until you have completed the configure section

and have returned to the admin prompt.

5. One at a time, re-enable the switches in the updated fabric. In a core/edge
network, enable the core switches first.

6. Once the fabric re-converges, type cfgEnable myZoningCfg, (where
myZoningCfg is the name of your zone configuration). Press Enter to
update zoning.

Note: This does not change the definition of zones in the fabric, but causes the lowest

tables in the zoning database to update with the new Core Switch PID format.

7. Repeat steps 3 through 6 for all fabrics in the SAN.

8. Bring the devices online in the order appropriate to the SAN. This usually
involves starting up the storage arrays first, and the hosts last.

9. For any devices manually bound by PID, bring the device back online, but do
not start applications. Update their bindings and reboot again if necessary.
This may involve changing them to the new PIDs, or may (preferably) involve
changing to WWN binding.

10. For any devices automatically bound by PID, reboot the device to rebuild the
device tree. (Some operating systems require a special command to do this.
E.g. boot –r in Solaris.)

11. For devices that do not bind by PID or have had their PID binding updated,
bring them back up and resume I/O.

12. Verify that all I/O has resumed correctly.

Note: Migrating from manual PID binding (e.g. persistent binding on an HBA) to

manual WWN binding and/or upgrading drivers to versions that do not bind by PID
can often be done before setting the core PID format. This can be advantageous, as it
prevents the update process from having as many variables.

Note: Once the switch PID format is set, it is stored in the flash memory of the switch,

and it is NOT necessary to set it again during subsequent firmware upgrades.

HP/UX Procedure for Updating the Core Switch PID Format

Use these procedures for updating the Core Switch PID format in an HP/UX
environment.

1. Back up all data. Verify backups.

2. If you are not using multi-pathing software, stop all I/O going to all volumes
connected through the switch/fabric to be updated.

3. If you are not using multi-pathing software, unmount the volumes from their
mount points using umount. The proper usage would be umount <mount
point>. For example:

umount /mnt/jbod

4. If you are using multi-pathing software, use that software to remove one
fabric’s devices from its configuration.

5. Deactivate the appropriate volume groups using vgchange. The proper usage
would be vgchange –a n <path to volume group>. For example:

vgchange –a n /dev/jbod

6. Make a backup copy of the volume group directory using tar from within /dev.
For example:

tar –cf /tmp/jbod.tar jbod

7. Export the volume group using vgexport. The proper usage would be vgexport
–m <map file> <path to volume group>. For example:

vgexport –m /tmp/jbod_map /dev/jbod

8. Login into each switch in the fabric

9. Issue the command switchDisable.

10. Issue the command configure and change the Core Switch PID Format to

1.

11. Issue the command switchEnable. Enable the core switches first, then the
edge switches.

12. Once you have done this to all switches in the fabric and verified that it has
re-converged properly, issue the command cfgEnable [effective zone
configuration] on one of the switches in that fabric. For example:

cfgEnable my_zones

13. Clean the lvmtab file by using the command vgscan.

14. Change to /dev and untar the file that was tared in step 4. For example:

tar –xf /tmp/jbod.tar

15. Import the volume groups using vgimport. The proper usage would be
vgimport –m <map file> <path to volume group> <physical volume path>.
For example:

vgimport –m /tmp/jbod_map /dev/jbod /dev/dsk/c64t8d0
/dev/dsk/c64t9d0

16. Activate the volume groups using vgchange. The proper usage would be
vgchange –a y <path to the volume group>. For example:

vgexport –a y /dev/jbod

17. If you are not using multi-pathing software, mount all devices again and
restart I/O. For example, mount /mnt/jbod

18. If you are using multi-pathing software, re-enable the affected path. The
preceding steps do not “clean up” the results from ioscan. When viewing the
output of ioscan, notice the that the original entry is still there, but now has a
status of NO_HW.

Figure 20: ioscan output

19. To remove the original (outdated) entry, use the command rmsf (remove
special file). For example:

rmsf –a –v /dev/dsk/c65t8d0

20. Validate that the entry has been removed by using the command ioscan
–funC disk. Notice in the figure below that the NO_HW entry is no longer

listed.

AIX Procedure for Updating the Core Switch PID Format

Use these procedures for updating the Core Switch PID format in an AIX
environment.

1. Back up all data. Verify backups.

2. If you are not using multi-pathing software, stop all I/O going to all volumes
connected through the switch or fabric to be updated.

3. If you are not using multi-pathing software, varyoff the volume groups. Type,

varyoffvg datavg

4. If you are not using multi-pathing software, unmount the volumes from their
mount points using umount. For example:

umount /mnt/jbod

5. If you are using multi-pathing software, use that software to remove one
fabric's devices from its configuration.

6. Remove the device entries for the fabric you are migrating. For example, if the
HBA for that fabric is fcs0, execute the command:

rmdev -Rdl fcs0

7. Login into each switch in the fabric.

8. Issue the switchDisable command.

9. Issue the configure command. Change the Core Switch PID Format to 1.

10. Issue the configenable, (effective_zone_configuration) command.
For example:

configenable my_config

11. Issue the switchEnable command. Enable the core switches first, then the
edge switches.

12. Rebuild the device entries for the affected fabric using the cfgmgr
command.
For example:

cfgmgr -v

This command may take several minutes to complete.

13. If you are not using multi-pathing software, varyon the disk volume groups.
The proper usage would be varyonvg <volume_group_name>. For example:

varyonvg datavg

14. If you are not using multi-pathing software, mount all devices again and
restart I/O. For example,

mount /mnt/jbod

15. If you are using multi-pathing software, re-enable the affected path.

16. Repeat for all fabrics.
