devfs - Devices file system
DESCRIPTION
The devfs filesystem manages a name space of all devices under the Solaris operating environment and is mounted during boot on the /devices
name space.
The /devices name space is dynamic and reflects the current state of accessible devices under the Solaris operating environment. The names
of all attached device instances are present under /devices.
The content under /devices is under the exclusive control of the devfs filesystem and cannot be changed.
The system may be configured to include a device in one of two ways:
By means of dynamic reconfiguration (DR), using, for example, cfgadm(1M).
For devices driven by driver.conf(4) enumeration, edit the driver.conf file to add a new entry, then use update_drv(1M) to cause
the system to re-read the driver.conf file and thereby enumerate the instance.
The device may be attached through a number of system calls and programs, including open(2), stat(2) and ls(1). During device attach, the
device driver typically creates minor nodes corresponding to the device via ddi_create_minor_node(9F). If the attach is successful, one or
more minor nodes referring to the device are created under /devices.
Operations like mknod(2), mkdir(2) and creat(2) are not supported in /devices.
FILES
/devices Mount point for devfs file system
SEE ALSO devfsadm(1M), vfstab(4), attach(9E)NOTES
The /devices name space cannot be unmounted.
All content at or below the /devices name space is an implementation artifact and subject to incompatible change or removal without notifi-
cation.

SunOS5.8 is a radical departure from SunOs4.X in many ways. one of the important differences is the handling of devices. Adding devices under SunOS4.x required a kernel reconfiguration, recompliation and reboot. Under SunOS5.X, this has changed with the ability to add some drivers on the fly.... (1 Reply)
How can I display the devices attached to my computer through the command line? And, how do I get information about each device listed? I'm looking to make sure that my DLT drive is recognized by the computer.
Using FreeBSD, if that helps.
Thanks! (1 Reply)

My /usr filesystem is sized at 3.8 gb. Check me if I'm wrong here but this should be enough space for /usr?

My problem is that it's running at 90% capacity. ... (2 Replies)
