SGI IRIX Installation
The SGI IRIX system creates device files for new devices automatically during server
startup.
IRIX uses the following formats for the device file names.
• parallel SCSI and FC-AL
/dev/rdsk/dkscontroller#ddrive#{spartition#|vh|vol}
/dev/rdsk/dkscontroller#ddrive#llun#{spartition#|vh|vol}
/dev/dsk/dkscontroller#ddrive#spartition#
/dev/dsk/dkscontroller#ddrive#llun#spartition#
/dev/rdsk/dks8d0l8s0
• Fibre Channel fabric
/dev/rdsk/nodename/lunlun#{spartition#|vh|vol}/ccontroller#pport#
/dev/dsk/nodename/lunlun#spartition#/ccontroller#pport#
/dev/rdsk/50000e10ff809999/lun1vol/c8p50000e10ff809999
The fabric device names always specify the logical unit number (lunlun#), even when
it is zero. The rdsk devices use a raw interface to communicate with the disk, and the
dsk devices use a block interface.
The ccontroller#, ddrive#, and llun# parameters indicate the SCSI controller number,
target ID, and logical unit number.
The pport# and nodename parameters are used to indicate the worldwide name
(WWN) and the device port number (Fibre Channel disks have two ports). The vh and
vol devices are in the rdsk directory only, because they are normally used only for ioctl
and raw access.
Fabric Switch
When the fabric switch is used, the WWN information is displayed by the nsShow
command. The PortName (column 4) is the WWN, and the NodeName is the device
port number.
