OSX Imaging with El Capitan...

03/31/2016 2590 views
Good day all,

After much trial and error, I was able to create a netboot environment so I can begin testing and learning how to image OSX.

Once I booted into the environment, I captured the image 'El Capitan 10.11.4' from a bootable USB I created and is plugged into the Mac I'm testing with. The image appears in the K2, I added some basic steps, then (I think) redeployed the image back to my Mac.

The image is about 5.83G
The Netboot environment is almost 18G. I was rather surprised at the sizes here, but I did do some research beforehand, so I'm not uncomfortable yet unless it is suggested otherwise.

My issue now however is that the machine appears to deploy the image very quickly and then drops me back off in the netboot environment, with a k2000 admin login screen. I thought maybe I just had to change the boot back to the HD, but the options now are Netboot and some "tmp OSX, 10.11.3.

10.11.3 was the base environment of my Mac itself, but I should've grabbed the image from the bootable USB.

Any ideas why I'm stuck in netboot, or even, how to tell if the image deployed successfully? Text scrolls by incredibly fast, the blue progress bars zips to about 98% while saying deploying image.


EDIT: I set the image to not restart automatically and I do get a message that it transferred the full size of the image. I'm restarting choosing the TMP location in hopes that hey, maybe there's a fresh 10.11.4 installation there, but I'm not confident.

It pushed out so quickly, which as a K-image, is much faster than my 8gig base Win7 WIM images.

EDIT 2: I booted back to the hard drive but it's pulling up my original OSX installation I always work with instead of wiping the disk and reinstalling.

I'm not positive but I think that you somehow got your NetBoot set and image backwards. The NetBoot set should be on the order of 4 or 5 GB. How did you create the NetBoot set?

  • Chuck,

    I installed Media Manager and selected the option for netboot.

    I named it and then pointed it towards my USB bootable El Capitan media. It took a long time, but when it was finally finished, I had an El Capitan boot environment.

    I was then able to netboot my Mac and it captured a ~5G El Capitan image.

    This site from Dell indicates the relative size and function of the netboot environment: https://support.software.dell.com/k2000-systems-deployment-appliance/kb/149735

    "*Note: In 3.7SP2, the 10.11 NetBoot Environment takes up approximately 17.5GB of space. However, the entire environment is not downloaded in order to boot. The client mounts the disk image over NFS, so it only grabs the part of the image that it needs. It is planned to resolve this issue in a future version."
    • We don't use the K2 for Mac Imaging and our NetBoot sets for DeployStudio are only about 4GB, which is why I asked. Is it possible when you uploaded your image that you uploaded the booted volume, which would be the NetBoot environment and not the internal drive?
      • I don't think so.

        All this said, I've reimaged my Mac overnight and am going to try and recapture again today, but pull from the HD instead of the USB bootable and see what happens.
