Cisco prime smart flash delete not working on 3850 image deployment

[Eric R. Jones]

We have several 3850 switches with 16.12.1 installed. 

We have Cisco Prime 3.7 with update 3.7 update 3.0 and device pack2.

When I deploy an image to our 3750's it works flawlessly.

When I deploy an image to our 3850's I get back the warning that there's not enough disk space.

When selecting "Smart Delete" and "Erase Running config" The job runs but doesn't remove the old image. The failure report states that there must be at least 2.2 X the size of the file. 

We then manually, using TFTP, uploaded and upgraded the 3850 with no issues.

Is this an issue with Prime not reading the information on the 3850 or is it the 3850 not supplying the proper snmp information to Prime?

Most confusing.

Means it is a bug.

I reviewed the last Prime patch and device updates looking for a bug but it wasn't in the last two.

My assumption is it's on the switch side but found nothing in the software checker.

- Compare  the current software version running on the 3850 and verify compatibility with current version of Cisco Prime :
