If you now click “Build”, & AutoCasperNBI will start the NBI creation process. The NetBoot Name field will auto populate, in the format of “ AutoCasperNBI”, the “NetBoot Image Index” will be set to a random number & the “Serve Image over” options will be shown. With both an OS.dmg & Casper Imaging.app selected, the rest of the main window will become available. If hdiutil can write to an image it has verified, attach will store an attribute with the image so that it will not be verified again unless its timestamp changes.” When selecting an OS.dmg for the 1st time, AutoCasperNBI may appear to “hang” This is as the OS.dmg is silently mounted using hdituil attach. The reason for this can be found in the hdiutil man page: “hdiutil attach attempts to intelligently verify images that contain checksums before attaching them. Once you the version details have been found, the other options will become available. On selecting either, AutoCasperNBI will attempt to get their respective version details. On Launch, AutoCasperNBI’s opens with most options are greyed out, this is by design.
Lastly, if you are creating NBI’s in an environment where packages used in the imaging process are hosted on a JDS instance, then you will also need to create an AFP share as outlined here. If you have any issues in setting this far, the following (despite it’s age) is still the best resource to help you in “ Troubleshooting the NetBoot process.” Apple also has some documentation available.Īlso, enabling verbose booting on a client can show where in the process things are failing & there can be issues with non-Apple Thunderbolt or USB adaptors as well as model filtering on the NBI’s too. That is when Apple releases a “fork” of the OS for a new iteration of hardware. NOTE: Only use Composer in the case of forked builds. 10.7+ NBI’s can be created on 10.9+ Macs running AutoCasperNBI. NBI’s created with AutoCasperNBI really should be created from a clean never booted Operating System disk image (read: OS.dmg).Ĭlean OS.dmg’s can be created via AutoDMG, Casper Admin or Composer (see “Building OS Packages” in the Casper Suite Administrator’s Guide.)Īlso, with AutoCasperNBI the OS versions do not have to match. This can be tested by creating a vanilla NetBoot Image via System Image Utility, once created upload it to your NetBoot server of choice. Or via Boot Picker which is accessed by holding the Option key on startup.
