Can a schedule in the snapshot policy be associated with two different prefix names?

I am using the command following to create snapshot policy:

>volume snapshot policy create -policy snapshot_app1 -enabled true -schedule1 daily2030  -count1 15 -prefix1 snapshot_app1_15days_daily

 

If I wanted to use the the same schedule "daily2030", and use different prefix name, say prefix2, it won't allow me to do that. Is there anyway i can use the same schedule but with different prefix name?

Hello @heightsnj 

 

A snapshot policy can not contain same schedule with different prefix. You will have to create a separate policy and add the original schedule desire and specify the new prefix. Per example:

 

cluster::> snapshot policy add-schedule -policy >policy name< -schedule daily2030  -prefix <>

1.     After several tests, it looks to me that the same schedule can only be used in a policy and not in different policies. That sounds weird to me as for what logical reasons behind that. In some cases, what if I wanted to use the same schedule for different policy? why cannot be allowed?  That  was my original question. 

 

2.     As different than what @hmoubara said, " snapshot policy add-schedule " only can be used if I use a different schedule into the same policy. So, the command as suggested below was incorrect:
cluster::> snapshot policy add-schedule -policy >policy name< -schedule daily2030  -prefix <>

Hello @heightsnj 

 

Doing further checking you are right,  Every schedule has only one prefix. Once a prefix gets associated with a schedule, you cannot update the prefix. If some prefix is already associated with the schedule and you do not specify this parameter, then the previously defined prefix is used.
