Using FlexAddress 179
Enabled slots will be FlexAddress enabled for all fabrics that are enabled. For
example, it is not possible to enable Fabric-A and B, and have Slot 1 be
FlexAddress enabled on Fabric-A but not on Fabric-B.
Use the following RACADM command to enable or disable fabrics:
racadm setflexaddr [-f <fabricName> <state>]
<fabricName> = A, B, C
<state> = 0 or 1
Where 0 is disable and 1 is enable.
Use the following RACADM command to enable or disable slots:
racadm setflexaddr [-i <slot#> <state>]
<slot#> = 1 to 16
<state> = 0 or 1
Where 0 is disable and 1 is enable.
For additional information on the command, see the setflexaddr command
section of the Dell Chassis Management Controller Firmware Version 2.0
Administrator Reference Guide.
Additional FlexAddress Configuration for Linux
When changing from a server-assigned MAC ID to chassis-assigned MAC ID
on Linux-based operating systems, additional configuration steps may be
required:
• SUSE Linux Enterprise Server 9 and 10: Users may need to run YAST (Yet
another Setup Tool) on their Linux system to configure their network
devices and then restart the network services.
• Red Hat
®
Enterprise Linux
®
4(RHEL) and RHEL 5: Users will need to
run Kudzu, a utility to detect and configure new/changed hardware on the
system. Kudzu will present the user with The Hardware Discovery Menu, it
will detect the MAC address change as hardware was removed and new
hardware added.
