Hi Brandon,  VP Snap targets share tracks between themselves, not with the source volume. If you see a doc that says source and target share allocations, it is incorrect and should be corrected.  VP Snap sessions are “nocopy” sessions, aka copy-on-write sessions. Tracks will only copy to target to preserve that point in time as source tracks are written to.  Mike
All:  I have read all the documents I can get my hands on concerning Snap VP, but I am confused.  The documentation says that Snap VP shares allocations in the same thin pool between source and target devs.    I just established a new session using the following command:   symclone -g establish DEV001 sym ld DEV002 -full -vse   Why is it taking forever to "copy" when I query this?  What is it copying?    Thanks!
