PROBLEM: (CH_G04572) (PATCH ID: OSF540-132) ******** There was a change in the ioctl used by the setsysinfo system call handler when we went from v4.0 and 5.0a to v5.1. This ioctl had not been implemented for the KZPCC driver. This caused consvar -s bootdef_dev to fail when used against KZPCC disks.
