Attaching Devices to Live Systems
Note that not all devices can be attached to a live system. Check your
system documentation before attempting the following procedure.
The following assumes that the device in question can be seen by the
system. It is possible that a reset will be required to
see a new SCSI device.
Several commands can help bring a device online under these circumstances:
- drvconfig: This command constructs files in
/devices
for the new device. Entries in several configuration files are used in
this process: /etc/minor_perm, /etc/name_to_major,
/etc/driver_classes.
- devlinks: This command creates the links from the
/dev
directory to the corresponding /devices file.
- disks:
disks creates links in /dev/dsk
and /dev/rdsk corresponding to disk devices in the
/devices directory.
- tapes:
tapes creates links in /dev/rmt
corresponding to tape devices in the /devices directory.
