I'm running Sybase ASE 15.7 and coming up to speed to clean up a database server installed by a non-DBA.

I have a database that has the following device configuration:
![Sybase database device listing](https://i.stack.imgur.com/bDt6W.png)

I want to have data1 and tlogs1 devices hosting only Data and Log respectively so that I don't encounter any anomalies in the event of a database restore due to a device failure.

How can I correct this configuration?

Note: The remove button is always grayed out.
