(In reply to Sarah Kriesch from comment #1) > Has SUSE a HyperPAV available to reproduce? SUSE has HyperPAV available (this is a storage feature, and devices must be configured in iocds). However to reproduce, you would need z/VM 7.2, because I am using minidisks without the first cylinder. This is a new feature available with z/VM 7.2 I did not try with dedicated disks and alias devices.
