High availability

The following features contribute to the Core Switch 2/64 and SAN Director 2/128 high-availability design:

• Redundant, hot-swappable components

• Redundant power and cooling subsystems

• Enhanced data integrity on all data paths

• Fabric Shortest Path First (FSPF) rerouting around failed links

• Integration with SNMP managers

• Automatic control processor failover

• Nondisruptive hot software code loads and activation

• Easy configuration, save, and restore

The high-availability software architecture of the Core Switch 2/64 and the SAN Director 2/128 provides a common framework for all applications that reside on the system, allowing global and local states to be maintained enough to manage any component failure. High-availability elements consist of the High Availability Manager, the heartbeat, the fault/health framework, the replicated database, initialization, and software upgrade.

The High Availability Manager controls access to the standby control processor, facilitates software upgrades, prevents extraneous switchover activity, closes and flushes streams as needed, provides flow control and message buffering, and supports a centralized active and standby state.

Reliability

The Core Switch 2/64 and the SAN Director 2/128 use the following error detection and correction mechanisms to ensure the reliability of all data inside the chassis:

• Power-on self test (POST)

• Error Detection and Fault Isolation (EDFI), such as cyclic redundancy checking (CRC), parity

checking, checksum, and illegal address checking

Overview18

Page 19

• Dual control processors that enable hot, nondisruptive fast firmware upgrades

Each control processor contains two serial ports and one Ethernet port. Offline control processor diagnostics and remote diagnostics simplify troubleshooting. The standby control processor continuously runs diagnostics to ensure it is operational, should a failover be necessary.

• I

C monitoring and control, used between Integrated Circuits (IC) to monitor how they are

working

Serviceability

The Core Switch 2/64 and the SAN Director 2/128 provide the following features to enhance and ensure serviceability:

• Modular design with hot-swappable components

• Redundant flash memory that stores two firmware images per control processor

• Extensive diagnostics and status reporting, along with a serial port to support an external,

country-specific modem for remote diagnostics and status monitoring

• Nonvolatile random-access memory (NVRAM), containing the HP serial number,

manufacturer’s serial number, revision information, and part number information

• Background health-check daemon

• Memory scrubber, self test, and bus ping to determine if a bus is not functioning

• Watchdog timers

• Status LEDs

• Predictive diagnostics analysis through Fabric Watch

• SNMP integration with higher-layer managers

Optional management features

Refer to the HP StorageWorks release notes for the Fabric OS running on your switch to get a complete list of management and optional software features enabled on the switch.

Interoperability

Fabric OS v4.x interoperates with HP StorageWorks switches running Fabric OS version 2.6 or later.

19Core Switch 2/64 and SAN Director 2/128 installation guide

Page 20

Security

Secure telnet access is available using Secure Shell (SSH), a network security protocol for secure remote login and other secure network services over an insecure network.

Advanced Web Tools management is available via a secure browser using Secure Sockets Layer (SSL). The SSL security protocol provides data encryption, server authentication, message integrity, and optional client authentication for a TCP/IP connection. Because SSL is built into all major browsers and web servers, installing a digital certificate turns on the SSL capabilities.

Network manageability

The Core Switch 2/64 and SAN Director 2/128 are each managed as a single element and appear as a single element to a Network Management System (NMS). The switch responds to its own IP address and appears as a separate entity to the telnet protocol and SNMP.

The management interfaces include blade assemblies as intermediate components between switches and ports. In addition, all management interfaces, such as telnet, Advanced Web Tools, the Fabric Access Layer API, and Management Server, support a port N within blade M naming scheme.

When SNMP devices send SNMP messages to a management console running SAN management software, the information is stored in a management information base (MIB). Fabric OS v4.x supports the latest Fibre Alliance Fibre Channel Management (FCMGMT) and Storage Management Initiative (SMI) MIBs, which allow common information necessary for management software to provide information to a SAN administrator.

NOTE: For additional MIB information, refer to the HP StorageWorks MIB reference guide for

the Fabric OS version running on your switch.

Management summary

The Core Switch 2/64 and the SAN Director 2/128 can be managed in-band using Fibre Channel protocol or out-of-band by connecting to the Ethernet port. The management functions allow you to monitor fabric topology, port status, physical status, and performance statistics.

The Core Switch 2/64 and the SAN Director 2/128 are compatible with the following management interfaces:

• Command Line Interface (CLI) through a telnet connection

• Advanced Web Tools, an integrated GUI

Installation overview

You can install the Core Switch 2/64 or SAN Director2/128 in one of the following ways:

• As a stand-alone unit on a stable table or lab workbench

• In a rack using the 14U Rack Mount Kit supplied with the switch

Selecting an operating location

Verify that the switch location meets the following requirements:

• Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on

the switch nameplate.

• Air flow of at least 350 cubic feet per minute, available in the immediate vicinity of the

Core Switch 2/64 or SAN Director 2/128.

• If you are installing the switch in an HP rack:

Installing and configuring the switch28

Page 29

• 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 that the rack is mechanically secured to insure stability in the event of an earthquake.

Cooling requirements

Install the switch so that air intake and exhaust for all components in the rack is flowing in the same direction.

NOTE: To ensure adequate cooling, install the chassis with the port side facing the aisle into

which exhaust air is released (usually called the service aisle). This prevents the fans from pulling in heated exhaust air.

Power requirements

Two AC power cords connect to the switch. The AC power source must meet these requirements:

NOTE: Installing each power cord using two separate sources ensures power supply

redundancy.

• 200 to 240 VAC, 50–60 Hertz

• Protected by a circuit breaker in accordance with local electrical codes

• Supply circuit, line fusing, and wire size that are adequate according to the electrical rating

on the chassis nameplate

• Grounded AC outlets installed by a licensed electrician and compatible with the power

cords

The switch includes 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.

HP recommends connecting two optional Power Distribution Units (PDUs) to the switch for power redundancy. The recommended PDU is E7671A. HP recommends that you do not connect the switch to the wall, because it would require two dedicated wall outlets. Using the PDU, you can connect more devices to a power source.

29Core Switch 2/64 and SAN Director 2/128 installation guide

Page 30

Two jumper cables (C19-C20) are provided to connect from the switch to the PDU. The recommended power cords to connect from the PDU to the wall are E7803A, E7805A, E7806A, E7808A, and E7809A.

Installing the switch as a stand-alone unit

The following items are required for this setup:

• Core Switch 2/64 or SAN Director 2/128

• AC power cords and cables supplied with the switch

Important rack mount guidelines

Review the following rack mount guidelines before proceeding with the installation.

WARNING! A fully populated Core Switch 2/64 or SAN Director 2/128 weighs

approximately 250 lbs and requires a minimum of two people and a hydraulic or assisted lift to install it.

Before installing, verify that the additional weight of the chassis does not exceed the rack’s weight limits or unbalance the rack, especially when some of the cards or power supplies are partially extended out of the chassis.

• Check that a minimum distance of 28.25 inches is between the front and back rails.

• Verify that the additional weight of the chassis does not exceed the rack’s weight limits.

• Check that all equipment installed in the rack is grounded through a reliable branch circuit

connection. Do not rely on a secondary connection to a branch circuit, such as a power strip.

• Verify that the rack has enough space. The Core Switch 2/64 and SAN Director 2/128

are 14U, or 24.11 inches high.

• Verify that the rack is stable.

• M5 Tinnermans (0590-2318) and M5 Torx screws (0515-0671) are required pieces of

rack mount kit hardware.

• Verify that all other equipment installed in the rack is connected to a reliable ground

connection; do not rely on connections to a branch circuit, such as a power strip.

• Plan for cable management before installing the chassis. Cables can be managed in a

variety of ways, such as by routing cables below the chassis, to either side of the chassis, or through cable channels on the sides of the rack.

• Verify that the switch has access to a minimum airflow of 350 cubic feet per minute.

• Ensure adequate cooling by installing the chassis with the port side facing the aisle into

which exhaust air is released (usually called the service aisle). This prevents the fans from pulling in heated exhaust air.

5. Loosen the clamping screw on each retainer, insert the power cords through the retainers

into the power receptacles on the Core Switch 2/64 or the SAN Director 2/128, and tighten the clamping screws.

The power cords are designed with left bends, so each should route to opposite sides of the chassis.

6. Ensure that the power cord has a minimum service loop of 6 inches available at the

connection to the switch and is routed so that it is not exposed to stress.

7. Connect the power cords to a power source with voltage of 200 to 240 VAC, 50 to 60 Hz.

8. Position AC power switches to position 1.

The AC power switches light up green when switched on and power is supplied.

NOTE: The switch automatically performs a power-on self-test (POST) by default each time it is

powered on. POST takes approximately 10 minutes and is complete when indicator light activity returns to its standard state. For information about LED patterns, see ”Interpreting LED

activity” on page 64).

CAUTION: To prevent a potential IP address conflict, do not connect the Core Switch 2/64 or

the SAN Director 2/128 to the network until the IP addresses are configured. See ”Core

Switch 2/64” on page 53 for additional information.

Establishing a serial connection

The initial communication to a Core Switch 2/64 or a SAN Director 2/128 switch requires a serial connection. Follow these steps to establish a serial connection and log in to the switch:

1. Verify that the switch is powered on and that POST is complete by verifying that all power

LED indicators on the 16-port cards and CP cards are displaying a steady green light.

2. Use the serial cable provided with the switch to connect the console port on the active CP

card to a computer workstation.

The console port is the second serial port from the top of the CP card; the active CP card is indicated by an illuminated (blue) LED (see ”CP cards” on page 68). The Active CP LED in the standby CP card should be off (not illuminated).

45Core Switch 2/64 and SAN Director 2/128 installation guide

Page 46

NOTE: The console port is intended primarily for use during the initial setting of the IP

address and for service purposes. If necessary, the adapter on the serial cable can be removed to allow for an RJ45 serial connection.

3. Access the switch using a terminal emulator application (such as HyperTerminal on

Windows 95, Windows 2000, or Windows NT, or TERM in a UNIX

environment).

NOTE: Both the Core Switch 2/64 and the SAN Director 2/128 support up to two telnet

sessions with administrative privileges at the same time.

4. Disable any serial communication programs running on the workstation (such as

synchronization programs).

5. Open the terminal emulator application and configure as follows:

•Bits per second: 9600

•Databits: 8

•Parity: None

•Stop bits: 1

• Flow control: None

6. When the terminal emulator application stops reporting information, press Enter.

7. Log in to the switch as admin. The default password is password.

NOTE: At the initial login, you are prompted to enter new admin and user passwords.

Manage cables

The SAN Director 2/128 cables can be managed in a variety of ways, including the routing them, as follows:

• Through the cable management tray

• Out either side of the chassis

• Through patch panels or cable channels on the sides of the rack

47Core Switch 2/64 and SAN Director 2/128 installation guide

Page 48

Two items are provided to assist with cable management:

• Cable management tray—The cable management tray is attached to the bottom of the

chassis (see Figure 12) and can be used to route the power cables and other cables down below the chassis or out the sides of the chassis. Routing the cables down through the holes in the management tray requires minimum of 3U (rack units) below the switch.

• Cable guides (pillars)—A set of 16 cable guides (pillars) are provided with the switch and

can be used to organize the port cables into logical groups, such as according to port quads (sets of four neighboring ports). The cable guides do not attach to the chassis (see

Figure 13).

Figure 13 Cable guide (pillar)

The cable guides serve to keep the cables evenly spaced and to hold them away from the port cards, making card replacement easier and preventing the cables from bending to less than the minimum bend radius.

CAUTION: Do not route the cables in front of the air exhaust vent, which is located at the top

of the port side of the chassis. Arrange the cables so that the minimum bend radius is not exceeded; for a 50-micron cable, the minimum bend radius is 2 inches under full tensile load and 1.2 inches with no tensile load. Tie wraps are not recommended for optical cables because they are easily overtightened and can break the optical cables.

To keep LEDs visible and make it easy to replace components, route cables down in front of the cards, not across adjacent cards or in front of the power supplies. Figure 14 provides an example in which cables for each card are routed in front of that card and are out of the way of other components.

Installing and configuring the switch48

Page 49

Leave at least one meter of slack for each fiber optic cable. This provides room to remove and replace the port card, allows for inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.

Use the cable guides provided with the switch to group the cables. These guides help to keep individual ports accessible by keeping the cables evenly spaced. If ISL Trunking is in use, grouping the cables by trunking group is recommended. The ports are color-coded to indicate which ports can be used in the same ISL Trunking group. Four ports marked with solid black ovals alternate with four ports marked with oval outlines.

NOTE: ISL Trunking is a Fabric OS feature that enables distribution of traffic over the

combined bandwidth of up to four ISLs between two directly adjacent switches, while preserving in-order delivery. For more information, refer to the HP StorageWorks features overview for the Fabric OS version running on your switch.

Due to the wavelengths used in transmitting data, a minimum length is required for cables that connect the Core Switch 2/64 or the SAN Director 2/128 ports to device ports, as follows:

• 9 microns, single-mode (SM)—2 meters

• 50 microns, multimode (M5)—2 meters

• 62.5 microns, multimode (M6)—2 meters

PID format summary

This section describes the process ID (PID) addressing format, which is one of several used in Fibre Channel operations. The PID 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.

A sample PID looks like this: 011F00

Many scenarios cause a device to receive a new PID. For example, a device can receive a new PID when the device is unplugged from one port and plugged into a different port. (This might occur when cabling around a bad port or when moving equipment around.) It may also occur when you change the Domain ID of a switch, which may be necessary when merging fabrics, or changing compatibility mode settings.

NOTE: All switches running Fabric OS version 4.0.x or later are shipped with the PID Format

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

Mixed fabric environment with different switch platforms

Fabric OS v2.6.2, v3.1.2, and v4.2.x introduced a new switch PID format: Extended Edge PID (format 2). Extended Edge PID is useful if you introduce a Fabric OS 4.2.x switch into a fabric that consists solely of Fabric OS v2.x and v3.x switches. Before adding a Fabric OS 4.2.x switch to such a fabric, refer to the HP StorageWorks Procedures user guide for the Fabric OS version running on your switch to get information on the Extended Edge PID format.

NOTE: Switches must operate with Fabric OS v2.6.2, v3.1.2, v4.2.x, and later to use the

Extended Edge PID format.

If Extended Edge PID is set (before a downgrade from the current Fabric OS release to an earlier Fabric OS release that does not support the Extended PID format), PID needs to be set back to a supported format, such as Core PID (format 1) or native PID (format 0).

Configuration overview

The Core Switch 2/64 includes two logical switches in one cabinet. Each switch can have up to 64 ports. The SAN Director 2/128 is a single switch in one cabinet. It can have up to128 ports. This section provides information about how each switch is configured.

Core Switch 2/64

The Core Switch 2/64 can contain up to two logical switches, each with its own configuration: one logical switch for any 16-port cards in slots 1–4, and one logical switch for any 16-port cards in slots 7–10.

The configuration information for both logical switches is stored in the WWN card and in the CP cards’ flash memory. The configuration settings are automatically mirrored to the standby CP card. In this way, the most current configuration is available even if the active CP card fails.

You can also back up the configuration by uploading the settings to a workstation using the configUpload command (see ”Backing up system configuration settings” on page 131), and you can download the settings to the active CP card using the configDownload command (see ”Restoring the system configuration settings” on page 132).

NOTE: HP recommends a routine backup of the configuration to ensure that the current

configuration is available if it is needed.

The Core Switch 2/64 configuration can be modified only through a login session to the active CP card. The switch supports up to two simultaneous telnet sessions (with administrative privileges).

NOTE: For fabric OS v4.1 or later, different logins are provided for each logical switch.

Logical Switch 0 has logins User0, Admin0, Factory0, and Root0. Logical Switch 1 has logins User1, Admin1, Factory1, and Root1. For versions earlier than v4.1, the same administrative login account applies to both logical switches. If the password is changed on switch 0, it is automatically changed on switch 1.

SAN Director 2/128

Configuration information for the SAN Director 2/128 is stored in the WWN card and in the CP cards’ flash memory. The configuration settings are automatically mirrored to the standby CP card. In this way, the most current configuration is available even if the active CP card fails.

NOTE: HP recommends a routine backup of the configuration to ensure that the current

configuration is available if it is needed.

You can modify the Core Switch 2/128 configuration only through a login session to the active CP card. The switch supports up to two simultaneous telnet sessions (with administrative privileges).

55Core Switch 2/64 and SAN Director 2/128 installation guide

Page 56

Configure IP addresses for CP cards

The Core Switch 2/64 and the SAN Director 2/128 Director each require three IP addresses, which are configured using the ipAddrSet command. IP addresses are required for both CP cards (CP0 and CP1) and for the switch.

NOTE: Use a block of three IP addresses that are consecutively numbered in the last octet. The

IP and gateway addresses must reside on the same subnet.

Resetting an IP address while the switch is online breaks any connections to that IP address and forces a restart of any HTTP, SNMP, and API daemons.

The addresses 10.0.0.0–10.0.0.255 are reserved and used internally by the switch.

The default IP addresses and host names for the Core Switch 2/64 and the SAN Director 2/128 CPs are as follows:

• 10.77.77.75 CP0 (the CP card in slot 5 at the time of configuration)

• 10.77.77.74 CP1 (the CP card in slot 6 at the time of configuration

Configuration changes can only be made via the active CP card. If the CP card in slot 5 is not the active CP card, disconnect the serial cable and connect it to the CP card in slot 6; then log in as admin.

Follow these steps to configure the IP addresses for both CP cards (from the active CP card):

1. Enter the ipAddrSet command at the prompt: include option 2 for the CP card in slot 5 or

3 for the CP card in slot 6.

Example:

swDir:admin> ipAddrSet -cp 2

2. Enter the requested information at the prompts.

The default information for the CP card in slot 5 is displayed.

Example:

Ethernet IP Address [10.77.77.75]:

Ethernet Subnetmask [255.0.0.0]:

Host Name [CP0]:

Gateway Address [0.0.0.0]:

Installing and configuring the switch56

Page 57

NOTE: The host name is the name assigned to the CP card. The same gateway address must

be used for both CP cards (these gateway addresses are referenced for the IP addresses).

3. Press Enter to update the IP address of the active CP card immediately.

4. Repeat these steps to configure the IP address of the standby CP card.

The IP address of the standby CP card is updated at the next reboot.

Configure IP address for the switch

The Core Switch 2/64 and SAN Director 2/128 each has its own IP address and corresponding subnet mask. The default IP address is 10.77.77.77 (base IP address for logical switch 0 in Core Switch 2/64).

CAUTION: Resetting an IP address while the switch has active IP traffic from such applications

as Fabric Manager, Fabric Watch, and SNMP can cause traffic to be interrupted or stopped. Changing the IP address causes a domain address format RSCN to be issued.

Follow these steps to configure the IP address for the Core Switch 2/64 or the SAN Director 2/128 (from the active CP card):

CAUTION: Configuration changes can be made only via the active CP card. If the CP card in

slot 5 is not the active CP card, disconnect the serial cable and connect it to the CP card in slot 6, and then log in as admin.

1. Enter ipAddrSet at the prompt.

2. Enter the requested information for this IP address at the prompts.

Example:

Ethernet IP Address [10.77.77.77]:

Ethernet Subnetmask [0.0.0.0]:

Fibre Channel IP Address [none]:

Fibre Channel Subnet Mask [none]:

The IP address is updated immediately.

57Core Switch 2/64 and SAN Director 2/128 installation guide

Page 58

3. Reboot the CP card by entering the reboot command at the prompt.

CAUTION: The terminal serial port can be used to monitor error messages through a serial

connection. HP does not recommend using the terminal serial port as a command interface during normal operations. If this port is not going to be in ongoing use, remove the serial cable and protect the port from dust by replacing the shipping cap.

Establish an Ethernet connection

After using a serial connection to configure the IP addresses for the Core Switch 2/64 or the SAN Director 2/128 (see ”Configure IP addresses for CP cards” on page 56 and ”Configure

IP address for the switch” on page 57), you can connect the active CP card to the local area

network (LAN) if desired.

NOTE: HP recommends connecting the CP cards to a private network/VLAN.

By establishing an Ethernet connection, you can complete the switch configuration using either the serial session or a telnet session. However, you must ensure that the Core Switch 2/64 or the SAN Director 2/128 are not modified from other connections at the same time.

To establish an Ethernet connection to the switch, follow these steps:

1. Remove the shipping plug from the Ethernet port on the active CP card.

2. Insert one end of an Ethernet cable into the Ethernet port.

3. Connect the other end to an Ethernet 10/100 Base-T LAN.

The Core Switch 2/64 or the SAN Director 2/128 can now be accessed by remote connection using any of the available management tools, such as telnet or the optional Fabric Manager application.

4. To complete any additional switch configuration procedures through a telnet session, log in

to the switch by telnet, using the admin login. The default password is password.

Installing and configuring the switch58

Page 59

Customize a switch name

The switch name of the Core Switch 2/64 or the SAN Director 2/128 Director can be up to 15 characters long; can include alpha, numeric, and underscore characters; and must begin with an alpha character. The default name for the Core Switch 2/64 or the SAN Director 2/128 is swDir. HP recommends using swDir in the name to allow easy identification.

To customize the name, follow these steps:

1. Enter the switchName command with the new name in quotes.

Example:

swDir:admin> switchName "sw10"

For details about the switchName command, refer to the HP StorageWorks command reference guide for the Fabric OS version running on your switch.

2. Record the new name for future reference.

NOTE: Changing the name causes a domain address format RSCN to be issued.

Specify status policies

To specify custom status policies, follow these steps:

1. Enter the switchStatusPolicySet command at the prompt.

For more information about the switchStatusPolicySet command, refer to the HP StorageWorks command reference guide for the Fabric OS version running on your switch.

2. Complete the prompts to specify the desired policies.

NOTE: To completely deactivate an alarm for a particular condition, enter 0 at the

corresponding prompt.

5. Enter a unique Domain ID:

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

6. Complete the remaining prompts or press Ctrl+D to accept the other settings and exit.

7. Enter the switchEnable command to reenable the Core Switch 2/64 or the SAN

Director 2/128.

Connect to the fabric and configure fabric parameters

Before connecting the Core Switch 2/64 or the SAN Director 2/128 to the fabric, verify that all the switches in the fabric use the correct port identifier (PID) settings. For information on setting the PIDs, refer to the HP StorageWorks procedures user guide for the Fabric OS version running on your switch.

To connect the switch to the fabric, follow these steps:

1. Add SFP transceivers and cables to the Fibre Channel ports, as required.

The ports are color-coded to indicate which ones can be used in the same trunking groups. Four ports marked with solid black ovals alternate with four ports marked with oval outlines. The ports and cables used in trunking groups must meet specific requirements. For a list of these requirements, refer to the “ISL Trunking” section of the HP StorageWorks features overview for the Fabric OS version running on your switch.

Installing and configuring the switch60

Page 61

2. Position one of the SFP transceivers so that the key is oriented correctly to the port. Insert the

transceiver into the port until it is firmly seated and the latching mechanism clicks.

Transceivers are keyed so that they can be inserted only with the correct orientation. If a transceiver does not slide in easily, ensure that it is correctly oriented. For instructions that are specific to the transceiver model, refer to the transceiver manufacturer’s documentation.

3. Position a cable so that the key (the ridge on one side of the cable connector) is aligned

with the slot in the transceiver; then, insert the key into the transceiver until the latching mechanism clicks.

Cables are keyed so that they can be inserted only with the correct orientation. If a cable does not slide in easily, ensure that it is correctly oriented.

4. Repeat step 1 through step 3 for the remaining ports.

5. Organize the cables as required. For recommendations regarding cable management,

refer to ”Manage cables” on page 47.

6. Check the Core Switch 2/64 or the SAN Director 2/128 for switch and port status by

entering the switchShow command at the prompt.

The switchShow command provides detailed information about the switch. For more information about this command, refer to the HP StorageWorks command reference guide for the Fabric OS version running on your switch.

7. Check the fabric for ISLs, switch names, or other status by entering the fabricShow

command at the prompt.

The fabricShow command provides general information about the fabric. For details about this command, refer to the HP StorageWorks command reference guide for the Fabric OS version running on your switch.

8. To establish additional system parameters, use the configure command. For details

about this command, refer to the HP StorageWorks command reference guide for the Fabric OS version running on your switch.

63Core Switch 2/64 and SAN Director 2/128 installation guide

Page 64

Interpreting LED activity

System activity and status can be determined through the activity of the LED indicators on the switch. There are three possible LED states:

• No light

• Steady light, in one of the following colors:

•Green

• Orange (also referred to as amber in related documentation)

• Yellow (appears when both green and orange LED elements are lit)

• Flashing light (green, orange, or yellow)

The LEDs may flash green, yellow, or orange while the switch is booting or while POST or other diagnostic tests are running. This is normal, and does not indicate a problem unless the LEDs do not indicate that all components are operational after boot process, POST, and any diagnostic tests are complete.

16-port cards

To determine the status of a 16-port card:

1. Check the LED indicators on the port card (see Figure 15).

The LED patterns may temporarily change during POST and other diagnostic tests. For information about how to interpret the LED patterns, refer to Table 7.

2. Check the 16-port card status using the slotShow command (see ”Obtaining chassis and

component status” on page 79 for an example).

Diagnostics and troubleshooting overview

For information about troubleshooting the entire fabric, refer to the HP StorageWorks procedures user guide for the Fabric OS version running on your switch.

The Core Switch 2/64 and the SAN Director 2/128 include a number of diagnostic aids to assist with troubleshooting, including LEDs on the hardware, commands that display current status, diagnostic tests for hardware and software, and error messages. In addition, a number of optional management tools are available, such as Fabric Manager, Fabric Watch, and Advanced Performance Monitoring.

If the switch does not operate as expected, use the following steps to diagnose the problem:

• Check the LEDs and refer to the LED tables (see ”Interpreting LED activity” on page 64) for

recommended actions.

• Review the results of the last POST run by the switch (see ”Interpreting POST and boot

results” on page 80).

• Review the error logs (for more information, refer to the HP StorageWorks system error

messages reference guide for the Fabric OS version running on your switch).

• Enter the sensorShow command to determine the status of the hardware components.

• Run diagnostic tests (see ”Diagnostics” on page 81).

• Reboot the switch or power the entire chassis off/on.

If the problem is still unresolved after these steps, contact your support provider. The information required by your support provider is listed under ”Rack stability” on page 11.

Operating the switch78

Obtaining chassis and component status

The CLI commands listed in Table 14 provide status and environmental information about the chassis and its components. These commands provide information only, and they do not interrupt traffic flow. For more information about these commands, refer to the HP StorageWorks command reference guide for the Fabric OS version running on your switch.

NOTE: The environmental commands report internal temperatures within the chassis. The

16-port cards can withstand internal temperatures of up to 75 continue to operate up to 80

Interpreting POST and boot results

The Core Switch 2/64 and the SAN Director 2/128 perform power on self test (POST) by default each time the chassis is powered on or the switch is rebooted or reset. You can reboot the switch using the switchReboot, reboot, or fastBoot commands. The fastBoot command reboots the switches without running POST. If the active CP card is rebooted, it fails over to the standby CP card.

POST

Each time the switch is powered on or reset, the switch automatically performs POST, a system check during which LED patterns might vary.

To verify that POST has completed without error:

• Verify that all LEDs return to a normal state after POST completes (see ”Interpreting LED

activity” on page 64).

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 relevant LED table to identify and correct the problem. For port cards and CP cards, the slotShow command can be used to check the status of the slots. For information about turning beaconing on/off, refer to the HP StorageWorks procedures user guide for the Fabric OS version running on your switch.

• Verify that the switch prompt appears when POST completes.

If it does not appear, POST was not successfully completed. Contact the switch supplier for support.

• Review the system log.

Any errors detected during POST are written to the system log, which is accessible through the errShow command. For information about error messages, refer to the HP StorageWorks system error messages reference guide for the Fabric OS version running on your switch.

POST includes the following steps:

• Preliminary POST diagnostics are run.

• Operating system is initialized.

• Hardware is initialized.

• Diagnostic tests are run on several functions, including circuitry, port functionality, ability to

send and receive frames, all aspects of memory, parity, statistics counters, and serialization.

Operating the switch80

Page 81

Boot

Boot completes in a minimum of three minutes if POST is run. In addition to POST, boot includes the following steps after POST is complete:

• Universal port configuration is performed.

• Links are initialized.

• Fabric is analyzed. If any ports are connected to other switches, the switch participates in a

fabric configuration.

• The switch obtains a Domain ID and assigns port addresses.

• Unicast routing tables are constructed.

• Normal port operation is enabled.

Diagnostics

Diagnostic tests are automatically run during POST to check the status of the switch. Any error messages generated during POST are sent to the error logs and to the serial console, if connected.

Diagnostic tests can also be run manually to test and troubleshoot the hardware and the firmware, including internal connections and circuitry, transceivers, and port cables. However, diagnostic tests are generally intended for use by support personnel.

NOTE: Diagnostic error messages do not necessarily indicate that the switch requires

maintenance.

Each diagnostic test can be implemented by entering the related command through a telnet or serial session. For a list of diagnostic tests and commands, refer to the HP StorageWorks procedures user guide for the Fabric OS version running on your switch.

All diagnostic tests are run at link speeds of both 1 and 2 Gb/s. They might temporarily lock the transmit and receive speeds to a specific speed. Some diagnostic tests require interconnecting the ports to each other or using loopback plugs. If ports are interconnected, the media (cables and transceivers) at each end of the connection must be of the same type. For example, short wavelength media must be connected to short wavelength media, and likewise with long wavelength media and copper media.

For more information about diagnostic tests and how to run them, refer to the HP StorageWorks procedures user guide for the Fabric OS version running on your switch.

Replacing the cable guides (pillars)

You can use cable guides (pillars) to organize the port cables into logical groups, such as port quads (sets of four neighboring ports). The cable pillars do not attach to the chassis.

The cable pillars also serve to keep the cables evenly spaced and hold them away from the 16-port card to prevent them from bending to less than the minimum bend radius.

CAUTION: Do not route the cables in front of the air exhaust vent, which is located at the top

To replace the cable pillars, orient them horizontally and insert the cables into the holes, using a separate hole for each cable (see ”Manage cables” on page 47).

Replacing a 16-port card and filler panel

This section describes how to remove and replace 16-port cards (see Figure 22) and 16-port card filler panels (see Figure 23) from the switch.

Preliminary steps

Take the following steps before removing and replacing a 16-port card:

1. Check the LEDs.

The LEDs are located on the front panel of each 16-port card (see Figure 15). Refer to ”16-port cards” on page 64 for a description of the 16-port card LEDs.

NOTE: The WWN bezel on the nonport side of the switch also displays a power and status

LED for each 16-port card.

2. Establish a telnet or console session.

Before replacing a 16-port card, establish a telnet or console connection to identify a failure and verify operation after replacement. For information about how to check the status of hardware components using the CLI, refer to the HP StorageWorks procedures user guide for the Fabric OS version running on your switch.

Installing FRUs90

Page 91

3. Check the cable slack.

Make sure there is plenty of cable slack to remove a 16-port card without any optical, power, or Ethernet cable obstructions. Refer to ”Manage cables” on page 47 for cabling guidelines.

4. Ensure that you have a valid spare part.

Make sure that the part numbers match for the unit being replaced. The chassisShow command displays information about the 16-port cards, including part numbers (xx-000xxxx-xx), manfacturer serial numbers, and additional status. The part number of each 16-port card is also printed on a sticker on the front panel of the card.

Replacing a 16-port card

Use the steps in the following sections to replace a 16-port card. The procedure requires:

• An ESD (electrostatic discharge) grounding strap

• Workstation computer

• Replacement port card or filler panel

• SFP transceivers (as needed)

• SFP cables (as needed)

Removing the existing16-port card

You can identify a failed 16-port card by inspecting its LEDs and by using CLI commands to verify status. Refer to ”Interpreting LED activity” on page 64 for a description of the LEDs.

CAUTION: Wear a grounded ESD strap when handling a 16-port card. The chassis has a

grounding connection above the power connectors. Hold the 16-port card by the edges of the metal pan. Do not use the ejectors to hold or carry a 16-port card.

Disassembling any part of a 16-port card or filler panel voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the 16-port card or filler panel

NOTE: Before removing any cables from the faulty 16-port card make a note of cable order

by referring a cable to the physical port; this reduces confusion during recabling. If multiple 16-port cards are being replaced, replace one card at a time. Before replacing a 16-port card, determine if it is the entire card or the SFPs that are faulty.

To remove a 16-port card, follow these steps:

1. Ensure that traffic is not flowing through the 16-port card (port LEDs should be off) prior to

disconnecting cables.

2. Disconnect any cables and SFP transceivers from the 16-port card.

3. Turn the 16-port card off by sliding the ON/OFF switch in the top handle down.

NOTE: You can also send hot-swap notification from the CLI using the commands

slotPowerOff and slotPowerOn.

4. Wait for the Power LED to turn off in response to the hot-swap request before uninstalling

the 16-port card.

5. Unscrew the captive screws from both handles.

6. Open both ejectors to approximately 45 degrees, and pull the 16-port card out of the

chassis.

NOTE: If you inadvertently relatch the ejectors prior to removing the 16-port card, wait at

least one second prior to unlatching the ejectors again.

7. If you are not replacing the card with another 16-port card, install a filler panel to ensure

correct cooling of the chassis and protection from dust. (See ”Installing a filler panel” on page 97 for more information.)

Installing a 16-port card

A 16-port card can be installed in any combination of slots 1–4 and 7–10. The control processor (CP) cards occupy slots 5–6. Any slots that are not occupied by a 16-port card (or CP card) should have a filler panel installed to ensure correct cooling of the chassis and protection from dust. See ”Removing a filler panel” on page 94 for instructions on removing this panel.

CAUTION: Do not force the installation. If the 16-port card or filler panel does not slide in

easily, ensure that it is correctly aligned inside the rail guides before continuing. Installing a 16-port card or filler panel with incorrect alignment damages both the chassis and the replacement part.

Wear a grounded ESD strap when handling a 16-port card. The chassis has a grounding connection above the power connectors.

Hold the 16-port card by the edges of the metal pan. Do not use the ejectors to hold or carry a 16-port card.

Disassembling any part of a 16-port card or filler panel voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the 16-port card or filler panel.

To install the new 16-port card, follow these steps:

1. Orient the 16-port card so that the ejectors are at the front of the chassis and the flat side of

the card is on the left.

2. Open the ejectors to approximately 45 degrees, align the flat side of the 16-port card

inside the upper and lower rail guides in the slot (see Figure 24), and slide the 16-port card into the slot, with slight pressure to the left, until it is firmly seated.

3. Close the ejectors by pushing the black handles toward the center of the port card until the

ejectors lock.

The levering action of the handles seats the 16-port card in the slot.

4. Verify that the Power LED on the 16-port card displays a steady green light (it can take a

few seconds to turn on). If it does not turn on, ensure that the 16-port card has power and is firmly seated.

NOTE: The LED patterns may temporarily change during POST and other diagnostic tests.

5. Install SFP transceivers and cables in the 16-port card, as required.

6. Group and route the cables as desired.

CAUTION: Do not route the cables in front of the air exhaust vent (located at the top of the

port side of the chassis).

7. Verify the installation. For information about checking the status of hardware components

using the CLI, refer to the HP StorageWorks procedures user guide for the Fabric OS version running on your switch.

Installing a filler panel

To install a filler panel:

1. Align the flat side of the filler panel inside the upper and lower rail guides in the slot (see

Figure 24); then, slide the filler panel into the slot (with slight pressure to the left) until it is

firmly seated.

2. Tighten the two captive screws.

Replacing a CP card

This section describes how to remove and replace a control processor (CP) card from the switch. Each switch has two CP cards: one located in slot 5 and the other in slot 6.

The switch can continue to operate while one CP card is replaced if the other CP card continues to operate and no failover occurs (you can prevent failover by entering the haDisable command). The active CP card is determined by the most recent failover.

The configuration on the active CP card is automatically mirrored to the standby CP card; this section includes steps to ensure that the new CP card boots up as the standby CP card.

The new CP card automatically assumes the IP address and host name assigned to the slot.

If the new CP card does not have the same firmware as the active CP card, you must upgrade or downgrade the firmware so that it matches the one on the active CP card.

CAUTION: Disassembling any part of a CP card voids the part warranty and regulatory

certifications. There are no user-serviceable parts inside a CP card. To ensure adequate system pressure for cooling purposes, leave the faulty CP card in the slot until you are ready to perform the replacement procedure.

CAUTION: Use the same version of Fabric OS on both CP cards. Using different versions can

cause malfunctioning. If the replacement CP card has a different version, update cards to the same firmware version.

WARNING! Do not attempt to replace the battery on a CP card. There is danger of explosion

if the battery is incorrectly replaced or discarded. Contact the switch supplier if the real-time clock begins to lose time.

Identifying a failed CP Card

The following indicators confirm that a CP card needs to be replaced:

• The Status LED on the CP card is yellow, or the Power LED is not ON.

• The slotShow command does not show that the CP card is enabled.

• The CP card does not respond to telnet commands, or the serial console is not available.

• The haShow command indicates that the CP cards have not achieved redundancy (after 30

minutes).

• The calendar clock is inaccurate, or the CP card does not boot up or shut down normally.

• Any of the following messages appear in the error log:

• Slot unknown message relating to a CP slot

• CP card errors or I

• FRU: FRU_FAULTY messages for a CP card

• Configuration loader messages or Sys PCI config messages

• Generic system driver messages, FABSYS

• Platform system driver messages

• EM messages that indicate a problem with a CP card

• Function fail messages for the CP master

C timeouts

Recording critical switch information

Back up the switch configuration before replacing a CP card.

To record critical switch information, follow these steps:

1. Create a serial connection to the healthy CP card:

a. Disable any serial communication programs running on the workstation (such as

synchronization programs).

b. Connect a serial cable to the terminal serial port (10101 Console Port).

c. Connect the other end of the serial cable to a serial port on the workstation. If

necessary, you can remove the adapter on the serial cable to allow for a serial RJ45 connection.
