MirrorAndVault not keeping destination snapshots?

billshaffer

Hello:

 

I have a MirrorAndVault snapmirror policy, with the defaults set to keep 7 daily and 52 weekly snapshots.  However, the destination volume only has the snapmirror created snapshots, despite the fact that dakly and weekly snapshots exist at the source volume.  I have the feeling that this is something stupid in the setup, but for the life of me I can't see it.  Can anyone explain this?  This is 9.5P6 (both sides).

 

Thanks...

Bill

Thank you Sergey - this was the missing piece.  The source snapshots are NOT labeled.  I assumed snapmirror was keying off the schedule name the way OnTap does for rotating snapmirrors.  Like I said, something stupid in the setup...
