NAME
dev - Device name file system
DESCRIPTION
The dev filesystem manages the name spaces of devices under the Solaris
operating system. The global zone's instance of the dev filesystem is
mounted during boot on /dev.
A subdirectory under /dev can have unique operational semantics. Most
of the common device names under /dev are created automatically by
devfsadm(8). Others, such as /dev/pts, are dynamic and reflect the
operational state of the system. You can manually generate device names
for newly attached hardware by invoking devfsadm(8) or implicitly, by
indirectly causing a lookup or readdir operation in the filesystem to
occur. For example, you can discover a disk that was attached when the
system was powered down (and generate a name for that device) by invok‐
ing format(8)).
The /dev/zvol/dsk and /dev/zvol/rdsk directories are generated based on
the ZFS dataset hierarchy. Each ZFS file system is represented in
/dev/zvol/dsk and /dev/zvol/rdsk as a directory. Each ZFS volume and
each snapshot of a ZFS volume is represented as a block device in
/dev/zvol/dsk and as a character device in /dev/zvol/rdsk. Within the
global zone, symbolic links to device nodes within /devices are used
instead of device nodes. See devfs(4FS).
Within non-global zones, the names that appear under /dev/zvol repre‐
sent the aliased dataset names. See zonecfg(8).
Within non-global zones, devices that are added by way of device
resources can have the same name as those that appear in the aliased
dataset namespace. See zonecfg(8). If such conflicts occur, the device
file corresponding to the device resource is seen and any corresponding
/dev/zvol entries for datasets that are delegated to the zone is not
seen. For example, if the device /dev/zvol/rdsk/rpool/vol1 is added as
a device resource and the within the non-global zone the volume
rpool/vol1 is created, the file /dev/zvol/rdsk/rpool/vol1 is the device
allocated from the global zone, not the one that appears within the
non-global zone's aliased dataset namespace.
