Checking integrity...
Integrity OK.
Running precreation scripts...
Precreation scripts done.
Determining the size of the archive...
The archive will be approximately 4.94GB.
Creating the archive...
Archive creation complete.
Running postcreation scripts...
Postcreation scripts done.

Running pre-exit scripts...
Pre-exit scripts done.

On the system that will be used as the installation server, create a JumpStart profile as you would to install any system. For example, the following profile is used to install the zfs10upflar archive.

install_type flash_install
archive_location nfs system:/export/jump/zfs10upflar
