Hello guys/gals,

I am trying to reproduce TimeFinder/Clone functionality on VMAX3. I would prefer not to use "emulation" and achieve the same thing using symsnapvx. One requirement is that clone target is a fully copy and not just a snapshot.  Here are the steps that i am attempting:

1) create target TDEVs same size as source TDEVs, add them to a storage group.

2) create snapshot

symsnapvx -sid 123 -sg sg_oracle -name snap establish

3) link to target TDEV, specify -copy to get full copy

symsnapvx -sid 123 -sg sg_oracle -snapshot_name snap link -copy -lnsg sg_snaptarget

so far so good, i can SRP utilization go up so it's making a full copy.

4) next i need to perform symsnapvx equivalent of symclone recreate. I don't see any options but to establish snapshot again

symsnapvx -sid 123 -sg sg_oracle -name snap establish

5) next i relink to target devices

symsnapvx -sid 123 -sg sg_oracle -snapshot_name snap relink -copy -lnsg sg_snaptarget

So these steps appear to achieve what i typically do with symclone, except for one thing. When i look at snapshots i see two snapshots with the same name.  I don't want multiple snapshots, i just need the one that i just established.  I can't terminate gen 1 snapshots because that will break "incremental" nature of this approach ? Am i understanding correct ?  If that's the case what are my options, setting TTL on each snapshot and let it auto expire after 25 hours or so ?

symsnapvx -sid 123 -sg sg_oracle list   -detail
