4Gb SAN Switch redundancy The HP c-Class BladeSystem was engineered as a no-single-point-of-failure bladed Solution. Attributes that contribute to switch redundancy include: • Redundant power and cooling • Redundant HP Onboard Administrator (OA) to ensure management access to the SAN Switch NOTE: The HP Onboard Administrator is the enclosure management module used to support and manage the HP c-Class BladeSystem and all managed devices used in the enclosure.
4Gb SAN Switch licensing The 4Gb SAN Switch integrates one of three license options that complement existing HP product lines. Some 4Gb SAN Switch models ship with licenses that place limits on the number of domains that can be used. Models and their specific licenses are described next: • Brocade 4/12 SAN Switch for HP c-Class BladeSystem, base, integrating 12 active ports (8 internal and 4 external) and two preinstalled short wavelength SFPs.
ISL trunking groups If your 4Gb SAN Switch is licensed for interswitch link (ISL) trunking, use the trunking groups available on the switch. The FC ports are numbered from left to right, and are part of the same ISL trunking group. The trunking group consists of the ports shown in Figure 2. NOTE: ISL Trunking is optional software that allows you to create trunking groups of ISLs between adjacent switches.
Optional hardware kits Table 4 lists optional hardware kits that support the 4Gb SAN Switch. For additional options, go to the HP web site: http://www.hp.

Each switch must be assigned a unique Ethernet IP address during configuration. Once the default Ethernet IP address on the 4Gb SAN Switch has been changed, you may install additional 4Gb SAN Switches in the enclosure. See the appropriate HP BladeSystem Enclosure Setup and Installation Guide for help identifying your specific enclosure setup, available connections and power requirements. Electrical considerations The 4Gb SAN Switch requires 35 watts, provided by the enclosure.
Install the 4Gb SAN Switch CAUTION: For switch revision levels 0A and 0B only (running Fabric OS versions earlier than 5.2.1b) — DHCP is not supported on these models. Do not install multiple switches at the same time with default addresses, as address conflicts will occur. Locate switch revision levels on the switch or shipping carton. See Set the IP address. For switch revision levels 0C and above only (Fabric OS 5.2.

25319a Figure 5 Installing the Brocade 4Gb SAN Switch into an interconnect bay 4. Press the installation handle into the latch to lock the Brocade 4Gb SAN Switch in place. OA verifies power As defined earlier, the HP BladeSystem Onboard Administrator (OA) is the enclosure management processor that manages the devices contained within the enclosure. The OA provides a single point from which to perform basic management tasks on switches or server blades installed in the enclosure.
Checking LEDs See Figure 6 to locate power-on LEDs. Verify that the LEDs match the indicators described in Table 7.
Setting the IP address IMPORTANT: The switch supports DHCP beginning with Fabric OS 5.2.1b firmware. For switches running Fabric OS 5.2.1b (switch rev 0C) or later, DHCP is enabled by default, simplifying multiple switch installations. To enable or disable this feature, login with these default credentials and issue the ipaddrset command using: • username: admin • password: password To set the Ethernet IP address: 1. Verify that the enclosure is powered on. 2. Verify that the switch is installed. 3.
Using External DHCP To set the Ethernet IP address using external DHCP: 1. Connect to the active OA via a web browser. 2. Document the DHCP-assigned address by selecting the switch from the OA GUI Rack Overview window. 3. Verify the IP address using a telnet or ssh login to the switch, or by selecting the switch in the OA GUI Rack Overview window.
6. Configure the terminal application as follows: In a Windows environment, type: • Bits per second — 9600 • Databits — 8 • Parity — None • Stop bits — 1 • Flow control — None In a UNIX environment, type: tip /dev/ttyb –9600 7. Log into the OA. 8. Press Enter to display the switch console. 9. Identify the interconnect bay number where the switch is installed. At the OA command line, type: connect interconnect x Where x is the interconnect bay slot where the switch is installed. a. User: admin b.
Configure the 4Gb SAN Switch The 4Gb SAN Switch must be configured to ensure correct operation within a network and fabric. For instructions about configuring the switch to operate in a fabric containing switches from other vendors, refer to the HP StorageWorks SAN Design reference guide: http://h18000.www1.hp.com/products/storageworks/san/documentation.html. For more information about the CLI, refer to the latest version of the Fabric OS command reference guide.
Connecting to the Command Line Interface Make an Ethernet cornnection and log into the 4Gb SAN Switch: 1. Connect the workstation to the Ethernet network containing the OA. If the OA is not on a network, connect directly to the OA/iLO Ethernet port on the active OA. IMPORTANT: Verify that the switch is not being re-configured from any other connections during the remaining steps. 2. Open a telnet connection using the IP address set earlier.
Setting the date and time Date and time are used for logging events. 4Gb SAN Switch operation does not depend on the date and time; a switch with an incorrect date and time value will function properly. To set the date and time using the CLI: 1. If you have not already done so, connect to the switch and log in as admin as described in Connect to the Command Line Interface. 2. Issue the date command using the following syntax: date “mmddHHMMyy” where: • mm is the month; valid values are 01 through 12.
Verifying installed licenses To determine the type of licensing included with your 4Gb SAN Switch, type licenseshow at the command prompt as in the following Example: Example 1. switch:admin> licenseshow XXXnnXXnXnnXXX: Fabric Watch license Release v5.0 license XXXnnXXnXnnXXX: Zoning license XXXnnXXnXnnXXX: Web license XXXnnXXnXnnXXX: Full Fabric NOTE: For more information about the Command Line Interface (CLI), refer to the latest version of the Fabric OS command reference guide.
Modifying the FC domain ID (optional) If desired, you can modify the FC domain ID. The default FC domain ID is domain 1. If the 4Gb SAN Switch is not powered on until after it is connected to the fabric and the default FC domain ID is already in use, the domain ID for the new switch is automatically reset to a unique value. If the switch is connected to the fabric after is has been powered on and the default domain ID is already in use, the fabric segments.
Disabling and enabling a switch By default, the switch is enabled after power on and diagnostics and switch initialization routines complete. You can disable and re-enable the switch as necessary. To disable: 1. If you have not already done so, connect to the switch and log in as admin as described in Connect to the Command Line Interface. 2. Issue the switchDisable command. All Fibre Channel ports on the switch are taken offline. If the switch was part of a fabric, the fabric reconfigures. To enable: 1.
Using Dynamic Ports On Demand (DPOD) In the past, Ports On Demand (POD) functionality was static. A preset group of ports were individually enabled per each POD license. In contrast, the new DPOD functionality does not require a predefined assignment of ports. Port assignment is determined by the total number of ports in use as well as the number of purchased ports. In summary, the DPOD feature simplifies port management by: • automatically detecting HBA connected server ports or cabled ports.
Example for Brocade 4/12 SAN Switch swd77:admin> licenseport -show 24 ports are available in this switch No POD licenses are installed Dynamic POD method is in use 12 port assignments are provisioned for use in this switch: 12 port assignments are provisioned by the base switch license *6 port assignments added if the 1st POD license is installed *6 more assignments added if the 2nd POD license is installed 4 ports are assigned to installed licenses: 4 ports are assigned to the base switch license Ports ass
NOTE: The DPOD feature does not consider disabled ports as candidates for license assignments. You can persistently disable an otherwise viable port to cause it not to come online and preserve a license assignment for future use. Verifying the configuration After setting initial parameters, verify the configuration as follows: 1. Check the LEDs to verify that all components are functional. For information about LED patterns, refer to Interpreting LED activity. 2.
