Table 14-1 FlexAttach Errors and Workarounds
Security Settings for FlexAttach Virtual pWWN
Security settings for the FlexAttach virtual pWWN feature are done by port security at the NPV core.
Node WWN of the end device is used to provide physical security.
For more details on enabling port security, see Chapter 46, “Configuring Port Security.”
Error Description Workaround
fc1/1 : interface is not
down
FlexAttach configuration
fails because the
configuration is enabled
for an active interface with
the operation state as up.
To move the port to the shut state, enable the
FlexAttach configuration, and then move the port
to no shut state.
FlexAttach
configuration is not
distributed to the peers
The FlexAttach
configuration on one peer
NPV is not available to any
other peer NPV.
FlexAttach configuration will not be distributed
if cfs ipv4 distribute, or cfs ipv6 distribute is
disabled. Enable cfs ipv4 distribute, or cfs ipv6
distribute.
Even with CFS
distribution enabled
Inagua does not
become a peer with
other NPVs
CFS over IP is enabled,
and the Inagua in one
blade center is not the peer
NPV for other NPVs.
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 disrtibuted to other peer NPVs in the
network.
NP port uses physical
pWWN instead of
virtual pWWN
confgured through
FlexAttach
This occurs whenNP port
uses physical pWWN
instead of virtual pWWN,
that is configured through
FlexAttach.
FlexAttach is supported on server interfaces like
F ports, and not on external interfaces such as NP
ports.
real port WWN and
virtual WWN cannot
be same
This occurs when you try
to configure FlexAttach
with a similar value for
pWWN and virtual
pWWN.
Use different values for pWWN and virtual
pWWN, as similar values for pWWN and virtual
pWWn are not allowed.
Virtual port WWN
already exists
This occurs when you try
to configure an already
defined pWWN to a
different interface.
Use an undefined virtual pWWN for a new
interface.
