How are you all managing snapshot policy after using snapmirror to move data?
This is for Data OnTap 9.1p2
For example, I have data on a netapp system in location A, where the RW volume has a snapshot policy taking a daily snap keep7 and a weekly snap keep 2.
i am closing that facility and need to transfer the data to location B. I setup a DP volume in location B where I am unable to set a snapshot policy so the volume gets a snapshot policy of "none"
Then I setup a snapmirror relationship between these 2 volumes to get the data to location B. Once i am ready an Operations team member performs the snapmirror break and mounts the volume allowing the rest of the team access and they are able to test. But unless the Operation team member modifiies the volume to have a snapshot policy it remains at "none" .
Does anyone have a method to manage this or a way to make sure that the policy gets set correctly?
i have a nightly script that checking my internal standards (see below). one of them is that a healthy relationship exists for each volume on all my clusters (which will then be monitored for LAGs in OCUM). where i have "$_.group.IsHealthy -contains $false", you can likely also add something like "or $_.group.policy -contains $null" (i didn't checked!). note that his report will not pick up any volumes without snapmirror at all (i have monthly report in OCUM for that)
The main idea in the script is to catch things that i know i/other might forget and that have caused issues before. the script is a bit too customized to my company to share it all as-is, but if you want more snipps - send me a DM.
