Hi,
The problem with that approach is that the only thing you may do with
an image in Error is delete it. Sometimes if the epilog phase fails
persistent images end up in Error. After checking that the images are
ok you may enable them so moving from error to rdy. As I said in this
case the admin is supposed to fix the erroneous condition of the image
before enabling it.
Cheers
Ruben
