31.7.2 Splitting an Image
You can split an image file into separate files so that you can span the entire image across several
CDs or DVDs.
When you split a device image and span it across several CDs or DVDs, you are essentially creating
a base image on the first CD or DVD. The remaining CDs or DVDs are add-on images.
Because images are split by placing individual files into different images, an image cannot be split if
it contains any single file that is larger than the specified maximum file size.
To restore a device image that has been spanned across several CDs or DVDs you should restore the
first CD or DVD before restoring the remaining CDs or DVDs containing the add-on images. For
more information, see
“Manually Putting an Image on a Device” on page 410 .
Restoring split Images is done using bundles, such as restoring a base plus add-ons. For more
information, see
“Creating an Add-On Image” on page 409 .
