QUESTION - is there an event for volume creation?

[emanuel]

Hello everyone.

Is there a way to generate an event when a new volume is created?

Thanks, Emanuel

[rshiva]

Hi Emanuel,

Check out the "volume-online" event. (dfm event list | grep -i volume-online)

Thanks and regards

Hello Shiva

We may be able to use the volume-online but if existing volumes come and go ( online / offline for whatever reason ) it may not work for this customer.  We will consider this for their use and see if it works for them.

Hi Emanuel,

     Shiva is right, we only have volume-online event we dont have volume discovered event like the one for volume-clone:discovered.

But adding little logic can help you verify if the volume was discovered or it went offline and came back online.

For a volume run this report.

dfm report view events-history <volumename-or-id>

The oldest event in the chronology for the volume offline is the time when this volume was created.

Another way, I can think of is parse the dfmmonitor.log.
