Brocade 8Gb SAN Switch for HP BladeSystem c-Class - Configuring

Configuring the 8Gb SAN Switch

The 8Gb 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 HP StorageWorks SAN Design reference guide .

top

Items required for configuration

The following items are required for configuring and connecting the 8Gb SAN Switch for use in a network and fabric:

  • 8Gb SAN Switch installed in the enclosure

  • IP address and corresponding subnet mask and gateway address recorded during the Set the IP address.

  • Ethernet cable

  • SFP transceivers and compatible optical cables, as required

  • Access to an FTP server for backing up the switch configuration (optional)

Connect to the command line interface

Make an Ethernet connection and log in to the 8Gb 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.

    NOTE: Verify that the switch is not being reconfigured from any other connections during the remaining steps.
  2. Open a Telnet connection using the IP address set earlier. The login prompt displays when the Telnet connection locates the switch in the network.

  3. Enter the user name, using the administrative account admin .

  4. Enter the password. The default password is password .

    NOTE: You can run up to two simultaneous admin sessions and four user sessions.

    If you have not changed the system passwords from the default, you are prompted to change them. Enter the new system passwords, or press Ctrl -c to skip the password prompts.

  5. Verify that the login was successful. If successful, the prompt displays the switch name and user ID to which you are connected.

Setting the date and time

The date and time are used for logging events. 8Gb 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.

  2. Issue the date command using the following syntax:

    date <mmddHHMMyy>

    where:

    • mm is the month; valid values are 01 through 12.

    • dd is the date; valid values are 01 through 31.

    • HH is the hour; valid values are 00 through 23.

    • MM is minutes; valid values are 00 through 59.

    • yy is the year; valid values are 00 through 99 (values greater than 69 are interpreted as 1970–1999, and values less than 70 are interpreted as 2000–2069).

For example:

switch:admin> date

Fri Jan 29 17:01:48 UTC 2000

switch:admin> date 0227123003

Thu Feb 27 12:30:00 UTC 2003

For details about changing time zones, see the tsTimeZone command in the latest version of the Fabric OS command reference guide.

Verifying installed licenses

To determine the type of licensing included with your 8Gb SAN Switch, enter licenseshow at the command prompt, as in the following example:

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 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 8Gb 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.

Enter fabricshow to determine the domain IDs that are currently in use. The maximum number of domains with which the 8Gb SAN Switch communicates is determined by this switch's fabric license.

To modify the domain ID:

  1. Enter switchdisable to disable the switch.

  2. Enter configure , and then enter a new value.

    Or press Enter to accept each default value.

  3. At the Fabric parameters prompt, enter Y and press Enter :

    Fabric parameters (yes, y, no, n): [no] y

  4. Enter a unique domain ID. For example:

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

  5. Complete the remaining prompts, or press Ctrl +D to accept the remaining default settings.

  6. Enter switchenable to re-enable the switch.

  7. Enter fabricshow to confirm any changes made to the domain ID.

  8. Optionally, verify switch policy settings, and specify any custom status policies that need to change:

    • Enter switchstatuspolicyshow to verify the current policy settings. If desired, enter switchstatuspolicyset at the prompt to change switch policy settings. This command sets the policy parameters that determine the overall switch status.

    • Customize the status policies as desired.

  9. To deactivate the alarm for a particular condition, enter 0 at the prompt for that condition.

Disabling and enabling a switch

By default, the switch is enabled after power on and after the 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

  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. If you have not already done so, connect to the switch and log in as admin

  2. Issue the switchEnable command.

    All Fibre Channel ports that pass the Power-on Self Test (POST) are enabled. If the switch has interswitch links (ISLs) to a fabric, it joins the fabric.

Disabling and enabling a port

To enable:

  1. Connect to the switch and log in as admin

  2. Issue portenable <portnumber> where portnumber is the port number of the port you want to enable.

To disable:

  1. If you have not already done so, connect to the switch and log in as admin as described in.

  2. Issue portdisable <portnumber> where portnumber is the port number of the port you want to disable.

Using Dynamic Ports On Demand (DPOD)

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

  • Automatically enabling ports

  • Automatically assigning port licenses

To initiate DPOD, use the licensePort command

NOTE: For the Brocade 8Gb SAN Switch, DPOD works only if the server blade is installed with an HBA present. A server blade that does not have a functioning HBA will not be treated as an active link for the purpose of initial POD port assignment.

DPOD commands

Use the licensePort command to manage dynamic POD assignments with the following options:

  • licensePort -reserve portnum reserves a future license assignment for a specific port, even if the port is currently offline.
  • licensePort -release portnum removes a license from a port.

  • portCfgPersistentDisable blocks a specific port from future assignments.

  • licensePort -show displays an overview of the POD license status and port assignments.

The following shows examples of the licensePort -show command for a Brocade 8/12 SAN Switch and a Brocade 8/24 SAN Switch:

Figure 1: Example 1

Figure 2: Example 2

NOTE: The DPOD feature does not consider disabled ports as candidates for license assignments. You can persistently disable an otherwise withble 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.

  2. Enter switchshow to get information about the switch and port status.

  3. Enter fabricshow to get general information about the fabric.

Backing up the configuration

To back up the switch configuration to an FTP server, enter configupload and follow the prompts. The configupload command copies the switch configuration to the server, making it available for downloading to a replacement switch, if necessary.
