Define SAN Fabric screen

To define a SAN fabric, select the Define SAN Fabric link on the home page, click Define SAN Fabric on the SAN Fabrics (Server Connections) screen (on page 155), click Add on the SAN Fabrics (External

Connections) screen (on page 153), or select SAN Fabric from the Define pull-down menu.

In FabricAttach mode, only connect HP VC 4Gb FC module, HP VC 8Gb 24-Port FC module, HP VC 8Gb 20-Port FC module, or FlexFabric FC uplinks to Fibre Channel switch ports that are NPIV-enabled.

NOTE: If using a Brocade FC switch, verify that NPIV is enabled properly by using the portshow command. If NPIV is not enabled properly, you might need to downgrade the Brocade switch firmware, and then upgrade the firmware again.

For VC 8Gb 24-Port FC Modules, if uplink port 8 is present in the VC SAN fabric definition, this port is treated as the lowest-numbered port and receives server logins before any other uplink ports.

In DirectAttach mode, connect the FC-capable uplink ports of the HP VC FlexFabric module to target ports on the 3PAR array controller node.

The following table describes the columns and fields within the Define SAN Fabric screen.

Column Description

Fabric Name Descriptive name for the virtual fabric. Do not use spaces.

Fabric Type The type of fabric. This option is available after a FlexFabric module port is added. Supported fabric types are FabricAttach and DirectAttach. The default type is

Column Description

FabricAttach. Select FabricAttach if the FlexFabric module is connected using traditional SAN switches. For this fabric type, the advanced settings appear, allowing you to change the login re-distribution and set the preferred and maximum connection speed. Select DirectAttach if the FlexFabric module is directly connected to a supported storage target. Login re-distribution is not applicable for a DirectAttach fabric; however, advanced settings are available for the preferred and maximum connection speed. After a fabric is defined, its type cannot be changed.

Login Re-Distribution Login Re-distribution setting for the fabric. For all standard VC-FC modules, this is always Manual. For FlexFabric modules, this can be set as described in "Login re-distribution (on page 149)" when the fabric type is set to FabricAttach.

Configured Speed Speed of the uplink ports, available after a port has been added. Valid values once allowed are 2Gb, 4Gb, 8Gb, and Auto. If 8Gb is chosen for the uplink speed on an FC module that does not support 8Gb, the value is automatically translated to "Auto" within VCM. This allows the module to connect at the highest supported speed. Uplink Port Number of the FC module uplink port

Enclosure Enclosure selected for the SAN fabric.

Bay Enclosure bay selected for the SAN fabric. Only uplinks on the same bay can be in the same SAN fabric.

Port Status Shows the link status, link speed, and connectivity of the port. If the port is unlinked and no connectivity exists, the cause is displayed. For more information about possible causes, see "Port status conditions (on page 261)."

Speed Port speed for the uplink ports in the fabric

Connected To WWN of the principal switch on the SAN fabric that this port is connected to on the other end

Action Perform delete operations

The following table describes the available actions in the Define SAN Fabric screen. Clicking another link in the pull-down menu or left navigation tree causes the current edits that have not been applied to be lost.

Task Description

Create a fabric name Type a name in the Fabric Name field. Do not use spaces. Add an uplink port Select a bay and port from the Add Port cascading menu. In

double-dense mode, do not select Bay 7 or Bay 8.

Set the uplink port speed After an uplink port has been added, click the pull-down arrow in the Configured Speed field, and then select a speed. The default value is Auto, which auto-negotiates the speed with the FC switch to which the ports are connected. If 8Gb is chosen for the uplink speed on an FC module that does not support 8Gb, the value is automatically translated to "Auto" within VCM. This allows the module to connect at the highest supported speed.

Set the fabric type After a FlexFabric module port has been added, click the pull-down arrow in the Fabric Type field, and then select a fabric type. The default value is FabricAttach, which indicates that the module is connected using traditional SAN switches.

Set the login re-distribution After a FlexFabric module port has been added, select the Show Advanced Settings checkbox, and then select manual or automatic. For more information, see "Login re-distribution (on page 149)."

Task Description

Set the preferred or maximum FCoE connection speed

After a FlexFabric module port has been added, select the Show Advanced Settings checkbox, click the selection box, and then select a setting (0.1Gb to 8 Gb):

• Set Preferred FCoE Connection Speed—Applies to server profiles with an FCoE connection specified. Select a speed value for the FCoE connection and server port associated with this fabric. • Set Maximum FCoE Connection Speed—Applies to server profiles

with an FCoE connection specified. This setting limits the maximum port speed from the server for the FCoE connection associated with this fabric.

Delete an uplink port Left-click an uplink port row to select it, right-click to display a menu, and then select Delete Port, or click Delete in the Action column.
