Normal product usage

Answer

You can run these DSCLI cmds to check progress:

* lspprc -l -fmt delim 0000-FFFF (for Metro Mirror and Global Copy)

Here is a sample output. Look at column 5 for Out of Sync Tracks (in this case the value is 225):

ID,State,Reason,Type,Out Of Sync Tracks,Tgt Read,Src Cascade,Tgt Cascade,Date Suspended,SourceLSS,Timeout (secs),Critical Mode,First Pass Status,Incremental Resync,Tgt Write,GMIR CG,PPRC CG,AllowTgtSE,DisableAutoResync
--------- ------------ - ----------- --- ------- ------- ------- - -- -- -------- ---- -------- -------- -------
1600:6600,Copy Pending,-,Global Copy,225,Enabled,Enabled,Invalid,-,16,60,Disabled,True,Disabled,Disabled,Disabled,Disabled,Disabled,False

* lssession -l 16-17 (for Global Mirror)
LSS ID Session Status Volume VolumeStatus PrimaryStatus SecondaryStatus FirstPassComplete AllowCascading
16 02 Normal 1600 Active Primary Copy Pending Secondary Simplex True Enable
17 02 CG In Progress 1700 Active Primary Copy Pending Secondary Simplex True Enable

*Note: FirstPassComplete=False can occur during initial full copy and also when copyset's OOS tracks gets to a high percentage (bandwidth cannot keep up with changing tracks), so cannot form CG groups

* showgmir -metrics 23 (for Global Mirror)
