NAME
devchassis - device name file system
DESCRIPTION
The chassis subdirectory of the /dev devfs(4FS) file system provides a
location-oriented name space. The /dev/chassis name space is maintained
by the devchassisd(8) smf service. The /dev/chassis name space is
structured by chassis, receptacle, and current occupant. Within the
chassis/receptacle name space, the current occupant is maintained as a
dynamic symlink into the /devices file system.
/dev/chassis/
<chassis-name>.<chassis-serial>[[/receptacle-name]*
[/<occupant-type> -> /devices/...]]
An empty receptacle is represented as an empty directory.
If an fmadm(8)—managed <alias-id> exists, then the <chassis-
name>.<chassis-serial> is replaced by a managed <alias-id>. A managed
<alias-id> can establish the physical location of chassis, like a
building, lab, rack, and chassis U-number range inside the rack.
There is always one well-known <alias-id> associated with internal
locations: SYS. This <alias-id> cannot be modified.
A <receptacle-name> is associated with chassis silk-screen labeling of
receptacles (like disk bays). Multiple <receptacle-name> directories
can be used before coming to an occupant symlink.
The /dev/chassis name space allows you to administer the machine based
on physical location.

/dev/chassis/RACK29.U05-08/DISK_00/disk
fmd(8) machine topology understanding is required to drive the creation
and maintenance of the /dev/chassis name space. If this understanding
is lacking, the /dev/chassis name space will be lacking. fmd(8) and
devchassisd(8) operation is coordinated using the contents of
/etc/dev/cro_db. This same data file is also used by the croinfo(8)
utility.
FILES
/dev/chassis Directory under the /dev file system mount point
that provides, when possible, a location-oriented
device name space.
/etc/dev/cro_db Data file created by fmd(8) used to obtain informa‐
tion about chassis, receptacles, and occupants.

NOTES
To prevent stale links, the entire /dev/chassis name space is removed
during each boot and reestablished when both fmd(8) and devchassisd(8)
are running. If devchassisd(8) is not running, the /dev/chassis name
space does not exist.
Gaps in fmd(8) topology representation result in gaps in the /dev/chas‐
sis name space.
