Just found out why I did not notice this before: When the disk is not present at mount time, the respective entry is not created in /dev/scsi/ and you get the traditional output. I think "status" should always give the traditional one as it has a fixed mapping between major/minor and device (see Documentation/devices.txt in the Linux sources), while the /dev/scsi/ entry has not. Maybe have the device in /dev/scsi/ in addition, if present, e.g. like this: root ~>cryptsetup status c1 /dev/mapper/c1 is active: cipher: aes-cbc-essiv:sha256 keysize: 256 bits device: /dev/sdd (/dev/scsi/sdh4-0c0i0l0) offset: 0 sectors size: 1953525168 sectors mode: read/write root ~> Arno On Sun, Jan 10, 2010 at 04:16:59PM +0100, Arno Wagner wrote: > Cryptsetup seems to report the device in /dev/scsi/* > if they are present, instead of the device name > mappings were created with.
