How to find associated volumes

Hi,

I am planning to run an audit over all of our offline volumes. I'd would like to that in small batches rather than importing a lot of offline volumes at once into the library. The problem is that the audit terminates if the respective volume contains a file which spans over more than one volume and the consecutive volume is not present in the library: ANR2456E AUDIT VOLUME: Unable to access associated volume xyz - access mode is set to "offsite".

Is there a way to find out which volumes are associated with a given one?

Thanks, Georg.
