There is no way of changing a device size. What you can do is add a new device and bind it to the master database.
If you want to decrease it, there is no way of doing that (a new install, but you don't want that I guess).

As Arjan mentioned above, there is no way af changing the size of any device at all.

Arjan suggested that you can create a new database device and alter the master database on it. This is not true. You cannot alter the master database on a new device. The only device you can use is the master decice. (alter database master on master =<size>)

When somehow your masterdevice is too small do the following.

1. Backup your masterdatabase
2. shutdown your server
3. Rebuild your master with the right size.(use the buildmaster command)
4. Start in single user mode (-m option in startserver) and load yuor dump af the master.
5. start Sybase and your up and running.

Succes, Albert

It is not possible to alter a master database on a device. The master database is created on your device while running the buildmaster command.

My above answer is correct and I'm waiting for my points.
