NAME

       devices, devid_cache, snapshot_cache, mdi_scsi_vhci_cache, mdi_ib_cache, devname_cache - device configuration information

SYNOPSIS

       /etc/devices

       /etc/devices/devid_cache

       /etc/devices/snapshot_cache

       /etc/devices/mdi_scsi_vhci_cache

       /etc/devices/mdi_ib_cache

       /etc/devices/devname_cache

DESCRIPTION

       The  directory  /etc/devices  is  a repository of device-related data. Files in this directory are used to preserve this information across
       reboots and are created and updated as necessary by the system.

       There are no administrative actions necessary with respect to files in /etc/devices. Should the contents of a file become corrupted  or	an
       update fail, the file can simply be removed. The system re-creates the file as necessary.

       Files  in  this	directory  do not constitute an API. Files might not exist or might have a different content or interpretation in a future

NAME

       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.
