VSE/VSAM catalogs on SCSI disks

At the VM workshop I had a discussion about SCSI configuration. A question was: Can a VSE/VSAM master catalog be allocated on an ECKD disk and the user catalogs / files on a SCSI disk ?
The answer is yes. z/VSE supports both. The master catalog can also be defined on a SCSI disk and user catalogs on ECKD.
However, once a file is started on a particular device type, it can only be extend on the same device type
That is you can setup mixed ECKD and SCSI environments as well as the traditional ECKD only - or SCSI only environments.
