I just setup a new ZCM 2017 appliance and noticed that the client agent update isn't showing up in System Updates. I'm trying to import it using the zman sui command, but am having difficulties figuring out how to access the ISO files on the appliance. I've always used SLES with ZCM 11.4 installed on it in the past so I've always just assigned the ISO in Vsphere settings and it showed up in the system and was accessible.

This is what I tried so far.
1) Extract ISO and copy to server. I later found out this method isn't supported as mentioned in TID 7015386.
2) Copy ISO to server and mount it using mount -o loop Zenworks2017a.si /mnt/ISO, but I get a message saying wrong fs type, bad option, bad super block on /dev/loop0.
