The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=7872131605f65d3e1cc651ba7113a9214013787a commit 7872131605f65d3e1cc651ba7113a9214013787a Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2023-07-27 22:05:29 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2023-07-28 04:28:01 +0000 cam: Fail 2/0 asc/ascq return code This asc/ascq code 2/0 ("No seek complete") is a fatal error on modern drives indicating a sensor failure. One of our vendors noticed we retried 2/0 so many times in their failure analysis and asked why (no other OS else does). They've indicated that this failures means the track couldn't be located (something that's not going to change, except if the environment changes significantly, which won't happen on a timescale useful to retries).
