Exadata The disk has been confined and is in an offline state
Error DescriptionData hard disk entered confinement offline status. The LUN 0_7 changed status to warning - confinedOffline. CellDisk changed status to normal - confinedOffline. All subsequent I/Os on this disk are failed immediately. Confinement tests will be run on the disk to determine if the disk should be dropped
Checked the AlerHistory from the Cell
#cellcli -e list alerthistory
2_1 2018-07-27T01:56:15+02:00 warning "Data hard disk entered confinement offline status. The LUN 0_7 changed status to warning - confinedOffline. CellDisk changed status to normal - confinedOffline.

And the Alert is cleared
2_2 2018-07-27T02:01:03+02:00 clear "Data hard disk status changed to normal. Status : NORMAL Manufacturer : HGST Model Number : ST360057SSUN600F.0T Size : 8.0TB Serial Number : 1604P1SN9V Firmware : PAG1 Slot Number : 7 Cell Disk : CD_07_p_cel02 Grid Disk : DATA_CD_07_p_cel02, DBFS_DG_CD_07_p_cel02, RECO_CD_07_p_cel02"
So we can see from the cell alert that the disk has been temporarily ring-fenced for testing and not because of media errors but because it exceeded a performance threshold. As you can see from the alert, it passed the test and was subsequently put back into a normal state.
