Where are you making this change? Via the "media" tab and editing an
individual volume?
The "help" button in that dialog explains that image expiration and
volume expiration are not related.
You can change the expiration date for the selected volumes. This
date refers to the age of the volume and is the time at which the
volume is considered too old to be reliable. When the expiration date
has passed, a volume can still be read but will not be mounted for a
write.
When you add a new volume, there is no default expiration date.
The expiration date is not the same as the retention period for the
backup data on the volume. The expiration date that you can set in
this dialog refers only to the physical expiration of the volume and
is independent of the backup data written on the volume.
The backup data expiration date is managed separately by the
application that is using the volume. In the case of NetBackup, the
expiration date for the data is set as the retention level during
schedule configuration.
This is an example of the split between the "volume manager" (tape
devices, vmquery), and the "netbackup" application (images, data on
tape, bpimmedia). The "Change Volumes" dialog only affects the volume
manager side of things.
