Hi,
you have to check, if the disk was assigned to the correct controller.
To be sure, you can assign the disk manually:
1.) check options disk.auto_assign on both controllers (if on, the disk will auto assign, to do it manually set the option to off)
2.) swap the disk
3.) check with disk show -n, the replaced disk should be shown as not owned
4.) from the controller, which needs the disk, type: disk assign ........DISKNAME..... or disk assign all (if only 1 disk is unowned)
5.) change options disk.auto_assign back (if changed in Step1)
