Using luxadm Software

Using luxadm Software

The luxadm command is an administrative command for managing the Sun Enterprise Network Array (SENA) specifically the Sun StorEdge A5x00 disk array, the SPARCstorage Array (SSA), and the Sun Fire 880 internal disk arrays. The luxadm command performs a variety of control and query tasks, depending on the command-line arguments and options used. This chapter describes the command syntax for luxadm and explains how to specify or address an individual disk or disk array. The command line for luxadm must contain a subcommand. You can enter options, usually at least one enclosure name or path name, and other parameters depending on the subcommand. The basic syntax is as follows:When specifying a subcommand, you need to enter only as many characters as are required to uniquely identify the subcommand. For example, to run the display subcommand on an enclosure named box1, you could enter:You specify the device with which a subcommand interacts by entering a path name. The path name is the logical or physical path of a Sun StorEdge A5x00 SENA Interface Board (IB), Sun Fire 880 enclosure services device (SES), SPARCstorage Array or RSM controller, or individual Fibre Channel-Arbitrated Loop (FC-AL) device. A path name can also be the World Wide Name (WWN) of the Sun StorEdge A5x00 IB, an individual FC-AL disk, or the Sun Fire 880 SES.

You specify the device with which a subcommand interacts by entering a path name. The path name is the logical or physical path of a Sun StorEdge A5x00 SENA Interface Board (IB), Sun Fire 880 enclosure services device (SES), SPARCstorage Array or RSM controller, or individual Fibre Channel-Arbitrated Loop (FC-AL) device. A path name can also be the World Wide Name (WWN) of the Sun StorEdge A5x00 IB, an individual FC-AL disk, or the Sun Fire 880 SES. There are several ways to specify an individual disk or an array to luxadm. You can specify a path name, the World Wide Name (WWN), or the enclosure name. You can determine these values for an array or an individual disk by using the luxadm probe, enclosure_name, and display commands.A path name is either the complete physical or logical path name of an individual internal disk or the complete physical or logical path name to an array’s SES controller. To determine a logical path name, use the probe subcommand. To determine a physical path name, use the probe -p subcommand. Logical links to the physical paths for Sun Fire 880 devices are kept in /dev/rdsk and /dev/dsk.

The WWN for an array is a unique 16-digit hexadecimal value that is programmed into the firmware on the FC-AL backplane during manufacturing. Each array has its own unique WWN. When two backplanes are joined as a single array, only theWWN for the base backplane is used.  enclosure The box_name of a Sun StorEdge A5x00 IB or Sun Fire 880 SES that you assign with the luxadm enclosure_name subcommand.
