NEXUS 7000 zombie module on startup-config

[Rosa Ladera]

During a sw upgrade, 2 NX2000 were removed from NX7000.
After this, startup-config shows NX2000 interfaces in spite of the fact that fex and port-channel configuration were not present any more.
How can i remove NX2000 interfaces configuration from startup config file?
Thanks in advance.
Regards,
Rosa

Hello Rosa,

if you do a 'show vdc detail' there probably is more than one VDC being displayed. Try and delete everything but the default (vdc1), which cannot be deleted.

Switch#conf t

Switch(config)#no vdc vdc-name

Refer to this document for more info:

Rosa,

you can make a backup of the startup config first:
