HP StorageWorks Disk Array XP operating system configuration guide: SGI IRIX (A5951-96075, December 2005)

Configure disk array devices
Disks in the disk array are configuredusingthesameprocedureforconfiguring any new
disk on the host. This includes the following procedures:
1. Creating device files
2. Partitioning and labeling the devices
3. Enabling co
mmand tag queuing
4. Creating t
he file systems
5. Creating
and verifying the mount directories
6. Registe
ring, mounting, and verifying the file systems
Creating device files
The SGI IRIX system creates device files for new d evices automatically during server
startup.
The SGI 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#
Example
/dev/rds k/dks8d0l8s0
• Fibre Channel fabric
/dev/r
dsk/nodename/lunlun#{spartition#|vh|vol}/ccontroller#pport#
/dev/dsk/nodename/lunlun#spartition#/ ccontroller#pport#
Example
/dev
/rdsk/50 000e10ff809999/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 d
evices use a block interface.
The ccontroller#, ddrive#,andllun# parameters indicate the SCSI controller number,
target ID, and logical unit number.
