don't use the same host for this, typically you take snapshot of production volumes and present them to a backup server. Because these snapshot volumes will be identical, you don't want to mount them on the same host as production, it will confuse the host (logical volume manager).  There are procedures to change volume group header/disk signature to be able to mount snapshot volumes on the same host as production volumes ..but you need to figure out what that process is and test test test first, you could bring production system down if you are not careful.  For your test if you only have one host to play with, activate snapshots, remove SRC devices and only then present TGT devices. This will allow you to validate data is there.
Hi everyone,  I'm actually working in an environnement fully configured with TDEV (Thin Provisionning).  My customer is taking Snaps of over 250 luns using actually a Clariion CX-4 to then mount the Snap onto a BK server and save the data on the Snap onto tapes.  Now, they have a VMAX40K and want to replicate what they are doing with the Clariion in the VMAX.  I would like to test this so i could help the customer, but this is pretty much the first time i'm working with TimeFinder and am not too sure from where to start.  So, from the described situation, can anyone give me advice ?  Thank you,  Christian
