n1kv veth ports being blocked for no apparent reason

[ggnfs000]

I did it in vmware 5.5.0 esxi and during the migration of vSwitch0 to DVS, number of veth ports are blocked automatically. I am not sure what caused it. It says ports are blocked by admin. Since I am relatively new to nx-os, I am not sure where to start from and how. I hope more experienced users can pinpoint or occasions in which the port can be blocked automatically. Any help is appreciated https://www.dropbox.com/s/gopgmg4l3i2bhft/n1k-ports-blocked.port.SUNDAY.PNG?dl=0

I haven't worked with it yet, but found this on the internet:

thanks, i will give it a try on this one. On my instance i checked everything nothing seems wrong, but the port being blocked said Directio not being supported.
