fcp start: Partner WWNN must match local WWNN to start FCP

josso02 — Thu, 05 Jun 2025 05:24:25 GMT

NetApp Release 7.3.6P2 (FAS3020c)

I'm having trouble starting the FCP. It says "fcp start: Partner WWNN must match local WWNN to start FCP".

This system used to be a cluster but has been decommissioned recently and moved to PreProd environment. There's only one Disk shelf (DS14MK2 FC) connected to the controller (Stand-alone)

Here's the current setup:

*>fcadmin config

Local
Adapter Type State Status
---------------------------------------------------
0a initiator CONFIGURED. online
0b initiator CONFIGURED online
0c target CONFIGURED offline
0d target CONFIGURED offline

0a is connected to ESH Module A

0b is connected to ESH Module B

0c is connected to a SAN Fabric

0d is connected to a SAN Fabric

I entered into "Special Boot Menu" and chose "4a" to initialize the entire system but still it didn't let me start the FCP. I even tried changing the "nodename", after adding the FCP license (KB ID: 2013604) I tried with the below config too,

0a is connected to ESH Module A

0c is connected to a SAN Fabric

0d is connected to a SAN Fabric

Nothing made a difference. Any suggestions?

I can't follow KB ID: 2010727, as I don't have access to the partner controller anymore.

https://library.netapp.com/ecmdocs/ECMM1278252/html/cluster/failing_over/task/t_oc_fo_mng-unconfig-hw.html#t_oc_fo_mng-unconfig-hw - This didn't work either.

could you try the following?

FAS3020> halt

once halted, from CFE prompt;

CFE> set-defaults

CFE> unsetenv partner-sysid

CFE> boot_ontap

and after booting up,

what is the output of "cf status" command?

I was able to run commands in CFE prompt and after booting up, here's what the "cf status" says,

Cluster must be licensed and the system rebooted before using this command.

*>fcp start
fcp start: Partner WWNN must match local WWNN to start FCP under Single Image

That means the system still thinks that its part of an HA pair. 😞

What does the following command command say?

controller> fcp show cfmode

is it saying
fcp show cfmode: System is not clustered. Unable to show cfmode.

is it still showing "single_image" ?

Also, please make sure that the NVRAM card is in slot #1, not in slot#3.

You may check this with the command: (last character is the number one)

controller> sysconfig -a 1

It also could be stale LUN configuration options. KB 1013497 lists some steps to reset configuration.

JOSSO02 had re-initialized the system, (option 4a from boot menu), so I assume no stale LUNs.

@aborzenkov , thanks for the KB, its good information.

Right. In this case it most probably NVRAM slot.

Are we expecting a below output from sysconfig -a 1? The below output is from another stand-alone production system.

yes , this is what is required for standalone system.

Moving the NVRAM back to Slot 1 did the trick. Thanks guys for your precius time and sharing your knowledge. It was much appreciated.
