Table 32: FlexAttach Errors and Workarounds
Error
fc1/1 : interface is not down
FlexAttach configuration is
not distributed to the peers
Even with CFS distribution
enabled Inagua does not
become a peer with other
NPVs
NP port uses physical pWWN
instead of virtual pWWN
configured through
FlexAttach
real port WWN and virtual
WWN cannot be same
Virtual port WWN already
exists

Description
FlexAttach configuration fails
because the configuration is
enabled for an active interface
with the operation state as up.
The FlexAttach configuration
on one peer NPV is not
available to any other peer
NPV.
CFS over IP is enabled, and
the Inagua in one blade center
is not the peer NPV for other
NPVs.
This occurs when NP port
uses physical pWWN instead
of virtual pWWN, that is
configured through
FlexAttach.
This occurs when you try to
configure FlexAttach with a
similar value for pWWN and
virtual pWWN.
This occurs when you try to
configure an already defined
pWWN to a different
interface.
Configuring FlexAttach Virtual pWWN
Workaround
To move the port to the shut state, enable the
FlexAttach configuration, and then move the
port to no shut state.
FlexAttach configuration will not be
distributed if cfs ipv4 distribute, or cfs ipv6
distribute is disabled. Enable cfs ipv4
distribute, or cfs ipv6 distribute.
CFS over IP uses IP multicast to discover the
NPV peers in the network. IBM MM does not
support multicast and cannot act as a peer with
NPV. This prevents the FlexAttach
configuration from getting distributed to other
peer NPVs in the network.
FlexAttach is supported on server interfaces
such as F ports, and not on external interfaces
such as NP ports.
Use different values for pWWN and virtual
pWWN, as similar values for pWWN and
virtual pWWn are not allowed.
Use an undefined virtual pWWN for a new
interface.
