| Subject: scsi: sd: Defer spinning up drive while SANITIZE is in progress |
| |
| From: Mahesh Rajashekhara <mahesh.rajashekhara@microsemi.com> |
| |
| commit 505aa4b6a8834a2300971c5220c380c3271ebde3 upstream. |
| |
| A drive being sanitized will return NOT READY / ASC 0x4 / ASCQ |
| 0x1b ("LOGICAL UNIT NOT READY. SANITIZE IN PROGRESS"). |
| |
| Prevent spinning up the drive until this condition clears. |
