Hi @kamil_drywa ,
Validate that all disks are assigned to the HA pair you wish to configure.
Using option 4 from the boot menu should initialize all disks that are seen by the system for a new configuration.
Depending on the version of ONTAP that is being configured you should be asked to configure a cluster managment interface, and later in the config process will be told to use this cluster management interface IP to set up the cluster via the GUI.
If you've assigned all disks and attempted the boot menu option 4, then please provide the console snippet from the process, so we can see what is occurring.
