SnapMirror history

[michael_england]

I'm having a bit of trouble getting actual history from my snapmirror relationships.  There's a command in 8.3+ (which I have) like this:

snapmirror show-history -destination-path va-fs2:lab_fs1_testvol_vault

-or-

snapmirror show-history -relationship-id e09b94b3-7c26-11e6-8d8f-00a098574311

The problem is, it'll only show me the last transfer, no actual history.  My mirrors are of type XDP (snapvault), could that be why or am I just doing something wrong?

Destination Path: va-fs2:va-fs2:lab_fs1_testvol_vault

Source Path: lab-fs1:testvol

It shows the history only for last 24 hours. 

I have volumes with diffrent schdules .

for the volume which replicate once a day , I see only one entry. 

For the volumes which replicate 3 times a day , I see 3 entries

If you have Unified manager, in OCUM we can see below history until a year old

1) Data transfer size 

2)  Transfer time 

3)  Lag time
