Hi Koray, Go back to the process of your directory change.
Is MAINT or DIRMAINT the leading directory owner? (take a look at the DIRMAINT 1DB, if there is a recent USER BACKUP chances are DIRMAINT was leading) Are you sure the correct directory has been put online? Did you have a DIRECT USER on the A or B disk? Is DIRECT USER C indeed the directory that you should use? (usually the directory is called USER DIRECT. So either there should be a file with that name or your zVM guy has renamed it to DIRECT USER.)

But /dev/dasda1 seems as a part of LVM group. Maybe i remembered wrong. Anyway, i dont know why all these changed but now i need to change the default boot minidisk from 100 to 102, my 8 guests have this problem. I think its somewhere in ZVM side. How can i do it?
