Important Information about the Four Switch Limitation for 2/8 EL Models Only

The SAN Switch 2/8 EL shipping configuration integrates the IV_Domain_Fabric license. The IV_Domain_Fabric license limits the number of switches that can be connected to a single fabric to four. If more than four switches (of any type) are added to the fabric where 2/8 EL switches are installed, Web Tools generates multiple error messages. Read the following sections for specific error messages and workarounds related to the four switch limitation.

Note: Upgrade the 2/8 EL to full fabric support by installing an optional upgrade

license. See the “Four Switch Limitation Workarounds” section on page 27 for instructions on how to purchase the Full Fabric license.

Check the License Installed

To verify the switch’s current license, use the command:

licenseshow

You do not have to delete the IV_Domain_Fabric license before upgrading to the Full Fabric license.

Four Switch Limitation Errors

The following section summarizes the error messages generated when more than four switches are installed in a fabric with the SAN Switch 2/8 EL.

Note: An operator can build a SAN with more than four switches by upgrading the

SAN Switch 2/8 EL to Full Fabric. To upgrade, you must install the optional Full Fabric license on each SAN Switch 2/8 EL. See the “Four Switch Limitation Workarounds” section on page page 27 for instructions on how to purchase the Full Fabric license.

Installing the SAN Switch 2/8

25hp StorageWorks SAN Switch 2/8 Installation Guide

Four Switch Limitation CLI Error Messages

If the fabric detects that the four switch limitation has been exceeded, the following message occurs every thirty seconds, via the Command Line Interface (CLI), as follows:

CRITICAL FABRIC-SIZE_EXCEEDED, 1, Critical fabric size <8> exceeds supported configuration <4>. Switch status marginal. Contact Technical Support.

WebTools will be disabled in 39 days 8 hours and 46 minutes.

The switch warning messages may be stored in the Syslog. Third party application SNMP traps may be configured on the switch.

Four Switch Limitation Web Tools Error Messages

If the fabric detects that the number of switches installed exceeds the four switch limit, Web Tools displays a warning message every 75 seconds (not configurable).

Figure 3 shows a typical Web Tools Warning Message.

Figure 3: Four switch limitation Web Tools error message

Note: The SAN Switch 2/8 EL displays a separate error condition warning message in

the dialog box.

Installing the SAN Switch 2/8

26 hp StorageWorks SAN Switch 2/8 Installation Guide

If the timer expires while trying to access Web Tools (for example, Zone Admin, Switch Admin, or Switch View), an HTML file similar to license.htm appears, stating that Web Tools is disabled. In addition, a prompt displays (see Figure 4) allowing you to install the optional Fabric license. After the Full Fabric license is installed, all Web Tools functionality resumes.

Figure 4: Full Fabric license install prompt in Web Tools

Violation Timer Errors

The violation timer begins decrementing when the four switch limitation is exceeded. The timer is cumulative. Resetting the power cycle will not reset the timer.

If the switch is moved to a fabric with less than five switches, the error condition is cleared; however, the violation timer stops counting down. If the switch is moved to a fabric with more than four switches, the violation timer continues from where it left off. When the accumulative violation timer reaches 45 days (not configurable), Web Tools for that switch is disabled. A message similar to

Figure 4 displays in a telnet session or error log.

Note: When Quiet Mode is enabled on a SAN Switch 2/8 EL with a IV_FABRIC

license installed, the four switch limitation warning messages display. If the IV_FABRIC license is not installed, Quiet Mode works as described in the

hp StorageWorks Fabric

OS V3.0.x/V4.0.x

Reference Guide

Installing the SAN Switch 2/8

27hp StorageWorks SAN Switch 2/8 Installation Guide

Additional Alerts

If the fabric size exceeds the four switch limit, the switch experiences the following activity:

■ In Fabric Manager and Web Tools, the switch icons in Fabric View turn

yellow for every 2/8 EL installed in a fabric that exceeds the four switch limit. For example, in Web Tools the following message appears in the bottom left hand corner of the window:

The Fabric has changed - - Reload / Refresh

Note: To prevent this message from reappearing, you must update to the

optional

Full

Fabric license.

Please note that removing the Ethernet connection will not eliminate this

message. See the “Four Switch Limitation Workarounds” section on page 27 in this chapter for instructions on how to purchase the Full Fabric license.

■ The switch beacons continuously, with front panel LEDs lighting amber,

similar to a firmware download. The switch stops beaconing during reconfiguration, switchdisable, switchenable. It also stops beaconing when the error condition no longer exists. Beaconing resumes if the error is detected again.

Four Switch Limitation Workarounds

Use one of the following workarounds to prevent four switch limitation errors.

■ Upgrade the current SAN Switch 2/8 EL IV_Domain_Fabric license to the

optional Full Fabric license. The Full Fabric license provides full fabric functionality, with no limits on the number of switches in the fabric.

For purchasing information, contact your authorized HP Sales representative, or go to the HP website:

http://www .hp.com

■ In fabrics which contain five or more switches and that have at least one

switch with the IV_FABRIC license installed, reduce the number of switches to four or less.

■ as a stand-alone unit on a flat surface, or

■ as a fixed component in the HP 9000 Series (or comparable) EIA Rack using

the Fixed Rack Mount Kit provided. Fixed Rack Mount Kit contents are outlined in Tabl e 3.

■ as a fixed component in the HP System/e rack models

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, HP System/e, or comparable

Electronics Industries Association (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 within the rack’s

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

Cooling Requirements

Caution: Do not block air vents. Blocking switch air vents may result in the switch

overheating.

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 of the chassis. HP recommends installing the switch so that air intake and exhaust for all components in the rack is flowing in the same direction.

Power On Self-Test

Each time the switch is powered on, rebooted, or reset, the switch automatically runs a Power On Self-Test (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

For example, 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” on page 60 in Chapter 3.

Note: For more information about beaconing, refer to the

Important Information on Setting the CORE PID Format

After connecting the SAN Switch 2/8 via Ethernet, you must verify that all switches you intend to connect to the SAN use the same Core Port Identifier (PID) format. A PID is one of two addressing mechanisms used in Fibre Channel. The PID is analogous to specifying the physical switch and port 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 In new installations, where both edge and Core switches reside, you must verify

that the edge switch (for example, SAN Switch 2/8) PID format matches the Core switch’s PID format, before connecting to the SAN.

For example, switches with firmware V3.0.2f or later have the PID set to 1. For a SAN to work correctly, all HP StorageWorks SAN switches or HP Surestore FC switches must have the same PID format setting, either 0 or 1. If a switch is introduced to an existing SAN with a setting that differs from the setting on the SAN, the switch will segment.

How to Check the Current Core PID Setting

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

Note: All switches in the SAN require the same PID format setting.

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:

3. Type switchDisable and press Enter.

4. Type configure and press Enter.

5. Type y at the Fabric parameters prompt, (yes, y, no, n): [no] y.

Installing the SAN Switch 2/8

52 hp StorageWorks SAN Switch 2/8 Installation Guide

6. 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.

7. Continue to press Enter until the admin prompt displays.

8. Type switchEnable and press Enter.

If necessary, proceed to the next section to change the Core PID setting to match all switches that will reside in the SAN.

How to Change the Core PID Format

Note: HP switches ship with the Core switch PID set to 1. HP recommends that if you

are in the process of creating a new SAN, set the PID to 1 for all switches in the SAN.

In order for the switches to interoperate properly, all of them must have the same Core PID format. Use these steps to change the Core PID format, if necessary.

Caution: If you need to change the PID format on this new switch, change the

PID format before connecting the fiber cables.

1. If the switch is configured for zoning, type cfgDisable to disable zoning.

2. To disable the switch, type SwitchDisable.

3. To reset the PID format, use the “configure” telnet command. Type configure. The following displays:

Configure...

4. Type y at the Fabric parameters prompt, Fabric parameters (yes, y, no, n): [no] y

5. Locate the line, "Core Switch PID Format: (0..1) [0] 1," and type 1.

6. Press Enter until the following prompt appears.

Installing the SAN Switch 2/8

53hp StorageWorks SAN Switch 2/8 Installation Guide

Committing configuration...Done

7. At the prompt type, SwitchEnable.

8. After setting the Core PID to match the the other switches in the fabric, go to the “Connecting the SAN Switch 2/8 to the LAN” section on page 50 in this chapter, for instructions on connecting Fibre Channel cables.

9. If necessary, type cfgEnable to re-establish zoning.

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.

Modifying Domain IDs

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

Note: It is best to assign a unique domain ID prior to connecting the switch to other

switches in the SAN. This eliminates the possibility of domain ID overlap.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. To disable the switch, type:

switchDisable

2. Enter the following:

configure

Installing the SAN Switch 2/8

54 hp StorageWorks SAN Switch 2/8 Installation Guide

3. Enter y after the Fabric Parameters prompt.

1. Remove the shipping plugs 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.

Installing the SAN Switch 2/8

56 hp StorageWorks SAN Switch 2/8 Installation Guide

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 17.

Figure 17: Inserting a cable into an SFP

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

Installing the SAN Switch 2/8

57hp StorageWorks SAN Switch 2/8 Installation Guide

Note: HP strongly recommends backing up the configuration. 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 “Backing Up System Configuration

Settings” on page 68 in Chapter 4.

Installing Multiple Switches into an Existing SAN

Use these steps to set up more than one SAN Switch 2/8 in an existing SAN.

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

2. Connect the Serial cable, provided in the carton contents, between a host computer and the Serial port of the switch. See the “Setting Network

Addresses via a Serial Connection” on page 47 to make a serial connection

through a workstation and to set the IP address.

3. 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.

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.

Installing the SAN Switch 2/8

58 hp StorageWorks SAN Switch 2/8 Installation Guide

Cascading Switches

The domain id number uniquely identifies a switch in a fabric. Normally, the switch automatically assigns the domain ID when a switch is first powered on or when the switch disable/enable command is executed. When two switches are cascaded together, there might be an initial domain ID conflict if the switches had been assigned the same domain ID prior to being cascaded. This can be avoided by changing the domain ID with the configure command.

The domain address may change when disabling and enabling one of the switches, or rebooting one of the switches if the domain is not set using the configure command. Switch parameters for all switches in a SAN must be the same, or the switch may not join the SAN.

Diagnostic Tests

Diagnostic tests help troubleshoot the hardware and the 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, as well as 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 V3.0.x/V4.0.x Procedures User Guide.

FTP must be used on Windows workstations to back up the system configuration. The FTP server must be running before an upload can occur. Use the RSHD service or FTP on a UNIX machine.

Note: The two supplied utilities,

RSHD.EXE

and

CAT.EXE

currently do not support uploads for Windows, only downloads. These utilities are available from the support website:

http://www.hp.com/support

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. Log in 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 prompts you for each parameter, as follows:

Example:

switch:admin> configupload Server Name or IP Address [host]: 123.45.678.901 User Name [user]: kelev File Name [config.txt]: switch1 Protocol (RSHD or FTP) [rshd]: ftp Password: upload complete
