DNAC Imaging Issue

[Sravan]

Hello there,

I'm having a bit of trouble reimaging my first gen DN1-HW-APL.

I followed the installation guide and tested various ISO versions / diff USB3.0 drives, still seeing the same error.  

I am able to boot from the USB and fill out the maglev wizard, but after the wizard completes and generates the certificates ..etc I'm getting configuration failed window with the following message - 

/dev/sdb1 is apparently in use by the system: will not make a filesystem here!

Every time I get this message, I have to flash the USB with the ISO image again.

Bit confused on why the installation wizard is trying to make changes to the USB drive instead of HDD.

Any guidance you can provide would be appreciated.

Thank you

I would create TAC case for this if you've got a service contract for it - this isn't normal DNAC SW install behaviour. You might have more luck installing an older version of DNAC SW.
