Disk Devices

z/VSE supports the following types of disk devices:
  • FBA (Fixed Block Architecture)
  • ECKD (Extended-Count-Key-Data)
You can use a combination of FBA and ECKD disk devices in your hardware configuration.

For initial installation, you need two disk devices (volumes) of the same device type and with the same capacity.
