Hello, I'm new to Compellent Storage and with my new position was asked to "figure out" our replay situation. 

We have quite a few volumes set up and about half of them have old, expired replays from 3 or 4 years ago. In System Manager most just say:

State: Frozen

Source: Created by user

Create volume: {deleted volume}

Some say source as "created by schedule" and actually have a volume listed under Create Volume.

My understanding is that several years ago there was some kind of issue and they went thru and created new volumes from these replays and then attached those volumes to servers and they're now being used as new volumes. That's what someone told me anyway.

So I have several questions:

1) Is there a way to tell where these replays are now being used as active volumes?

2) Is there a way to get rid of the expired replays so we can reclaim the storage, without effecting anything - specifically the new volumes that were created off them?

3) We replicate most of our LUNs to a different data center and most of the time the replays get stuck and we get way behind on the replication. Looks like replication is only using about 50megs of our 100meg pipe, even tho there's not much else using the replication link. Is there some other way we should be configuring things? Right now we have our replay schedule to go once per hour.

Thanks for any and all help. I plan on calling support, but would like to be more armed with knowledge and have stuff to look at on my side before calling them
