- CHAPTER 1
Using the luxadm Command
The luxadm Command
- The luxadm program is an administrative command that manages both the Sun Enterprise Network Array and SPARCstorage Array subsystems. luxadm performs a variety of control and query tasks, depending on the command line arguments and options used.
Synopsis
- The command line must contain a subcommand.
-
luxadm [options] subcommand [options] {enclosure[,dev]... |
pathname...}
|
- You may also enter options, usually at least one enclosure name or pathname, and other parameters depending on the subcommand.You specify a device by entering a physical path name, or a logical path name. See "Addressing".
- You only need to enter as many characters as are required to uniquely identify a subcommand. For example, to run the display subcommand on an enclosure named box1, you could enter:
-

Pathname
- Either a complete physical path name or a complete logical path name may be entered to specify the device or controller. A typical physical path name for a Sun Enterprise Network Array device is:
-
/devices/sbus@1f,0/SUNW,socal@1,0/sf@0,0/
ssd@w2200002037000f96,0:a,raw
|
- or
-
/devices/io-unit@f,e0200000/sbi@0,0/SUNW,socal@2,0/sf@0,0/
ssd@34,0:a,raw
|
- For all Sun Enterprise Network Array IBs (Interface Boards) on the system, a logical link to the physical paths is kept in the directory /dev/es. An example of a logical link is /dev/es/ses0.
Enclosure
- For the Sun Enterprise Network Array subsystem, the WWN may be used in place of the pathname to select a device or the Sun Enterprise Network Array subsystem Interface Board. The WWN is a unique 16 digit hexadecimal value that specifies either the port used to access the device or the device itself. A typical WWN value is: 2200002037000f96.
- Or you can specify the name of the Sun Enterprise Network Array enclosure and an identifier for the particular device in the enclosure. A device in a Sun Enterprise Network Array enclosure is identified as followe;
-
BOX_NAME,[f|r]slot_number
|
- where:
-
TABLE 1-1
| Options/Arguments | Description |
|
| BOX_NAME | is the name of the Sun Enterprise Network Array enclosure,
as specified by the enclosure_name subcommand |
| f or r | specifies the front or rear slots in the Sun Enterprise Network Array enclosure |
| slot_number | is the slot number in the Sun Enterprise Network Array enclosure, 0-6 or 0-10 |
- When addressing the Sun Enterprise Network Array subsystem the pathname or enclosure name specifies the Sun Enterprise Network Array Interface Board (IB).
Addressing a SPARCstorage Array
- When addressing the SPARCstorage Array, the pathname specifies the SPARCstorage Array controller or a disk in the SPARCstorage Array. The controller name is specified by its physical name, for example
-
/devices/.../.../SUNW,soc@3,0/SUNW,pln@axxxxxxx,xxxxxxxx:ctlr
|
- or by a name of the form cN, where N is the logical controller number. luxadm uses the cN name to find an entry in the /dev/rdsk directory of a disk that is attached to the SPARCstorage Array controller. The /dev/rdsk entry is then used to determine the physical name of the SPARCstorage Array controller. A disk in the SPARCstorage Array is specified by its logical or physical device name, for example,
-
- or
-
/devices/.../.../SUNW,soc@3,0/SUNW,pln@axxxxxxx,xxxxxxxx/
ssd@0,0:c,raw
|
- See the disks(1M) and devlinks(1M) manpages for more information on logical names for disks and subsystems.
Addressing a SPARCstorage RSM Tray
- When addressing the SPARCstorage RSM tray, the pathname specifies the controller or a disk in the SPARCstorage RSM tray. The controller name is specified by its physical name, for example
-
/devices/sbus@1f,0/QLGC,isp@1,10000/sd@8,0:c,raw
|
- or by a name of the form cN, where N is the logical controller number. luxadm uses the cN name to find an entry in the /dev/rdsk directory of a disk that is attached to the SPARCstorage Array controller. The /dev/rdsk entry is then used to determine the physical name of the controller. A disk in the SPARCstorage RSM tray is specified by its logical or physical device name, for example,
-
- See the disks(1M) and devlinks(1M) manpages for more information on logical names for disks and subsystems.
Subcommand Support Matrix
- The following table lists the luxadm subcommands that are supported on the Sun Enterprise Network Array, the SPARCstorage Array, and SPARCstorage RSM trays. Subcommands that are preceded by -e are expert mode subcommands and should only be used by qualified system personnel.
