1 General description This section describes the features and capabilities of the McDATA 4Gb SAN Switch in an HP p-Class BladeSystem server blade chassis. The following topics are described: • Switch LEDs and controls, page 12 • FC ports, page 14 • Ethernet port, page 16 • Switch management, page 16 Fabrics are managed with the McDATA Web Server™ switch management application and the Command Line Interface (CLI).
Switch LEDs and controls The switch LEDs provide information about the switch’s operational status. These LEDs include the Identifier LED, System Fault LED, and Power LED. The Maintenance button shown in Figure 2 is the only front panel switch control and is used to reset a switch or to recover a disabled switch. Maintenance button Switch LEDs Figure 2 Front panel switch controls and LEDs Switch LEDs The switch LEDs shown in Figure 3 provide status information about switch operation.
System Fault LED (amber) The System Fault LED illuminates to indicate an over temperature condition or a POST error. Also illuminated on an internal firmware error (heartbeat blink 2), voltage fault, or corrupt config error (heartbeat blink 4). Heartbeat LED (green) The Heartbeat LED indicates the status of the internal switch processor and the results of the POST.
FC ports The switch has 2 external FC ports through which to connect to devices or other switches, and 8 internal ports connecting to the server backplane. Each of the external FC ports is served by a Small Form-Factor Pluggable (SFP) optical transceiver and is capable of 1-Gbps, 2-Gbps, or 4-Gbps transmission. SFPs are hot-pluggable. External ports can self-discover both the port type and transmission speed when connected to public devices or other switches. The internal ports operate at 2-Gbps.
Port Logged-in LED (green) The Logged-in LED indicates the logged-in or initialization status of the connected devices. After successful completion of the POST, the switch extinguishes all Logged-in LEDs. Following a successful loop initialization or port login, the switch illuminates the corresponding Logged-in LED. This shows that the port is properly connected and able to communicate with its attached devices. The Logged-in LED remains illuminated as long as the port is initialized or logged in.
Ethernet port The Ethernet port shown in Figure 6 is an RJ-45 connector that provides a connection to a management workstation through a 10/100 Base-T Ethernet cable. A management workstation can be a Windows® or a Linux® workstation that is used to configure and manage the switch. You can manage the switch over an Ethernet connection using the McDATA Web Server, Command Line Interface (CLI), or SNMP. The Ethernet port has two LEDs: the Status LED (green) and the Activity LED (green).
File Transfer Protocol File Transfer Protocol (FTP) provides the Command Line Interface for exchanging files between the switch and the management workstation. These files include firmware image files, configuration files, and log files. Refer to the McDATA 4Gb SAN Switch for HP p-Class BladeSystem user guide for an example of using FTP to transfer configuration backup files.
General description
2 Planning Consider the following when planning a fabric: • Devices, page 19 • Device access, page 19 • Performance, page 20 • Multiple switch fabrics, page 21 • Switch services, page 22 • Fabric security, page 23 • Fabric management, page 25 Devices When planning a fabric, consider the number of public devices and the anticipated demand. This will determine the number of ports that are needed and in turn the number of switches. Refer to HP StorageWorks SAN Design manual for more information.
Table 2 Zoning limits Limit Description MaxZonesInZoneSets Maximum number of zones that are components of zone sets (2000), excluding the orphan zone set, that can be stored in the switch’s zoning database. Each instance of a zone in a zone set counts toward this maximum. MaxMembersPerZone Maximum number of members in a zone (2000) MaxMembersPerAlias Maximum number of members in an alias (2000) Zones Zoning divides the fabric for purposes of controlling device discovery.
You can use long wave SFPs and single mode cable to allow longer links up to 100km, but full bandwidth will not be achieved. You can configure recipient and donor ports using the McDATA Web Server application or the Set Config command using CLI. Refer to the McDATA 4Gb SAN Switch for HP p-Class BladeSystem user guide for information about the Set Config command. Bandwidth Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate.
Domain ID, principal priority, and domain ID lock The following switch configuration settings affect multiple switch fabrics: • Domain ID • Principal priority • Domain ID lock • The domain ID is a unique number from 97–127 that identifies each switch in a fabric. The principal priority is a number (1–255) that determines the principal switch which manages domain ID assignments for the fabric. The switch with the highest principal priority (1 is high, 255 is low) becomes the principal switch.
• Embedded GUI — provides for access to the McDATA Web Server. The web server enables you to point at a switch with an internet browser and run switch management application through the browser. The default is enabled. • Simple Network Management Protocol (SNMP) — provides for the management of the switch through third-party applications that use the Simple Network Management Protocol (SNMP).
• Refer to System keyword of the Set Setup command in the McDATA 4Gb SAN Switch for HP p-Class BladeSystem user guide for information about enabling the NTP client on the switch and configuring the NTP server. • Refer to the Set command in the McDATA 4Gb SAN Switch for HP p-Class BladeSystem user guide for information about setting the time zone. Device security IMPORTANT: Device security is available only with the McDATA SANtegrity™ Enhanced Product Feature Enablement (PFE) key.
Consider your management needs and determine the number of user accounts, their authority needs, and expiration dates. Also consider the advantages of centralizing user administration and authentication on a RADIUS server. NOTE: If the same user account exists on a switch and its RADIUS server, that user can login with either password, but the authority and account expiration will always come from the switch database. Fabric management The McDATA Web Server application and CLI execute on the switch.
Planning
3 Installation The McDATA 4Gb SAN Switch for HP p-Class BladeSystem provides integrated FC switch connectivity for single and dual density p-Class blade servers. The switch is compatible with any combination of server blade models in the HP BladeSystem enclosure that connects to the Ethernet Interconnect switch. These FC signal conditioning cards provide FC signal pass-through connectivity to ProLiant Blade servers. This section describes how to install and configure the McDATA 4Gb SAN Switch.
Environmental conditions Consider the factors that affect the climate in your facility such as equipment heat dissipation and ventilation.
Connect the management workstation to the switch Connect the management workstation to the switch in the following ways: • Indirect Ethernet connection from the management workstation to the switch RJ-45 Ethernet connector through an Ethernet switch or a hub. This requires a 10/100 Base-T straight cable as shown in Figure 8. With this method, you can manage the switch with the McDATA Web Server application or Command Line Interface.
Configure the switch You can configure the switch using the McDATA Web Server application or the Command Line Interface. Select the Open Configuration Wizard option in the Initial Start Dialog. Click Proceed to configure the switch using McDATA Web Server.
Cable devices to the switch Two 4-Gb SFPs ship with each McDATA 4Gb SAN Switch. It is recommended to use these SFPs rather than the 2Gb SFPs that ship with the BladeSystem. Connect cables to the SFP transceivers and their corresponding devices, and then energize the devices. Device host bus adapters (HBA) can have SFP (or SFF) transceivers or GigaBit Interface Converters (GBIC). LC-type duplex fiber optic cable connectors are designed for SFP transceivers, while SC-type connectors are designed for GBICs.
Using McDATA Web Server to install firmware Installing firmware involves loading, unpacking, and activating the firmware image on the switch. McDATA Web Server does this in one operation. To provide consistent performance throughout the fabric, ensure that all McDATA 4Gb SAN Switch for HP p-Class BladeSystem switches are running the same version of firmware. Verify that this version of firmware is compatible with the firmware of other McDATA switch models in the fabric.
Using the CLI to install firmware To install firmware using the CLI when a File Transfer Protocol (FTP) server is present on the management workstation, use the Firmware Install command. Refer to the McDATA 4Gb SAN Switch for HP p-Class BladeSystem user guide for information about this command.This command is disruptive to the fabric traffic. 1. Enter the following command to download the firmware from a remote host to the switch, install the firmware, then reset the switch to activate the firmware.
Installing Product Feature Enablement (PFE) keys A Product Feature Enablement (PFE) key is a password that you can purchase from your switch distributor or authorized reseller to enable particular features in your switch. The SANtegrity Enhanced PFE key enables device security on the switch. NOTE: To obtain the McDATA 4Gb SAN Switch serial number and Product Feature Enablement license key, follow the step-by-step instructions on the "firmware feature entitlement request certificate" for the PFE key.
4 Diagnostics and troubleshooting Diagnostic information about the switch is available through the switch LEDs and the port LEDs. Diagnostic information is also available through the McDATA Web Server and CLI event logs and error displays. This section describes the following types of diagnostics: • ”Switch diagnostics” on page 35 describes the Power LED and System Fault LED indications. • ”Power On Self Test diagnostics” on page 36 describe the Heartbeat LED and the port Logged-in LED indications.
Power On Self Test diagnostics The switch performs a series of tests as part of its power-up procedure. The Power On Self Test (POST) diagnostic program performs the following tests: • Checksum tests on the boot firmware in PROM and the switch firmware in flash memory • Internal data loopback test on all ports • Access and integrity test on the ASIC During the POST, the switch logs any errors encountered. Some POST errors are critical, others are not.
Configuration file system error blink pattern A configuration file system error blink pattern is 4 blinks followed by a two second pause. The 4-blink error pattern indicates that a configuration file system error has occurred, and that the switch configuration file must be recreated. Refer to ”Recovering a switch using maintenance mode” on page 41 for more information.
e. Enter one of the following commands and press Enter to establish communications with the switch using Telnet. telnet xxx.xxx.xxx.xxx or telnet switchname where xxx.xxx.xxx.xxx is the switch IP address and switchname is the switch name associated with the IP address. f. Enter an account name and password, and press Enter after the Telnet window opens and prompts you for a login. The default account name is “admin”. The default password is “password”. g.
If a Logged-in LED is flashing twice per second, review the event browser for alarm messages regarding the affected port. You can also inspect the alarm log using the Show Alarm command. If there is an error, alarm messages may point to one or more of the following conditions: • E_Port isolation, page 39 • Excessive port errors, page 40 E_Port isolation A Logged-in LED error indication is often the result of E_Port isolation.
NOTE: This can be caused by merging two fabrics whose active zone sets have two zones with the same name, but different membership. Excessive port errors The switch can monitor a set of port errors and generate alarms based on user-defined sample windows and thresholds. These port errors include the following: • CRC errors • Decode errors • ISL connection count • Excessive device logins • Excessive device logouts • Loss-of-signal errors Port threshold alarm monitoring is disabled by default.
Recovering a switch using maintenance mode A switch can become inoperable or unmanageable for the following reasons: • Firmware becomes corrupt • IP address is lost • Switch configuration becomes corrupt • Forgotten password In these specific cases, you can recover the switch using maintenance mode. Maintenance mode temporarily returns the switch IP address to 10.0.0.
Exiting maintenance mode The Exit option ends the current login session. Enter the maintenance mode account name and password (prom, prom) to log in again. Momentarily press and release the Maintenance button, or power cycle the switch to return to normal operation. Unpacking the firmware image file in maintenance mode The Image Unpack option unpacks and installs new firmware when the current firmware has become corrupt. Before using this option, you must load the new firmware image file onto the switch.
Recreating the switch file system in maintenance mode The Remake Filesystem option resets the switch to the factory default values including user accounts and zoning. In the event of a loss of power, the switch configuration may become corrupt. The file system on which the configuration is stored must be re-created. CAUTION: If you choose the Remake Filesystem option, you will lose all changes made to the fabric configuration that involve that switch, such as password and zoning changes.
