I have written a script to output the status of mirror replication for volumes to an HTML page. To obtain the status of the replication I am using Get-NcSnapmirrorHistory, this returns the status of each mirror replication over a 24 hour period.
The majority of volumes are returning the correct information however there are some volumes that return the information twice, i.e. On a volume that replicates at 0300, 0900, 1500 and 2100 I will see entries for 8/5/2018 0900, 8/5/2018 1500, 8/5/2018 2100 and 9/5/2018 as expected and then a second identical set of entries.
If I SSH to the filer and run a snapmirror show-history command for the volume, I don't get the same result as only one set of results is returned for the 24hr period.
Has anyone come across this previously and is there a resolution?
