HP Virtual Connect Manager 92

Select the uplink ports to be used. Only uplinks on the same bay can be in the same SAN fabric.

3. If the uplink ports selected are FlexFabric module ports, select the fabric type. Supported fabric types

are FabricAttach and DirectAttach.

o 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.

o Select DirectAttach if the FlexFabric module is directly connected to a supported storage target.

available for the preferred and maximum FCoE connection speed.

After a fabric is defined, its type cannot be changed. The default fabric type is FabricAttach.

4. If you are linking to an HP VC FlexFabric module and the fabric type is FabricAttach, click Advanced to

set the login re-distribution. For more information, see "Advanced SAN Fabric Settings (on page 92)."

5. Change the configuration speed, if preferred.

6. Click Apply.

In FabricAttach mode, connect only HP VC 4Gb FC Module, HP VC 8Gb 24-Port FC Module, HP VC 8Gb

20-Port FC Module, HP VC FlexFabric-20/40 F8 Module, or HP VC FlexFabric 10Gb/24-port Module

uplinks to Fibre Channel switch ports that are NPIV-enabled. 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.

Advanced SAN Fabric Settings

When creating or editing a SAN fabric using HP VC FlexFabric Modules in a FabricAttach fabric, select the

Show Advanced Settings checkbox to select the login re-distribution:

• Manual Login Re-Distribution—Default for all FC modules. You must initiate a Login Re-Distribution

request through the VC GUI or CLI interfaces. You might re-distribute logins if an uplink that was

previously down is now available, if you added an uplink to a fabric, or if the number of logins through

each available uplink has become unbalanced for any reason.

• Automatic Login Re-Distribution—When selected, the VC FlexFabric module initiates Login

Re-Distribution automatically when the specified time interval expires. For more information about

setting the time interval, see "Fibre Channel Settings (Misc.) screen" in the user guide.

The automatic option is only available on FlexFabric modules in a FabricAttach fabric and enables you to

specify an interval, in seconds, for the length of time the previously offline links must be stable before the

module can re-distribute logins. Login re-distribution is not supported for DirectAttach fabrics.

FCoE Connection Speed

To change these settings, click the selection box, and then select a setting (100Mb to 8Gb):

• Set a custom value for the Preferred FCoE Connection Speed. This value is the default speed for server

profile connections mapped to this fabric. The server administrator can override this setting on an

individual profile connection.
