Do your homework before play
We recently experienced some images that had failed to be expired on their own due to the known bug in 6.5 that won’t expire old 5.1 images from disk and it reminded me how very important it is to do your homework when taking drastic steps such as this. As we all know, once you use bpexpdate to get rid of an image, the only way to get it back is to import the tape(s). Before expiring those images, even if it is just one, use bpimmedia and bpimagelist to document what the images are and where they reside.
I find with this, Do your home work before playing with catalog images.
