About the Solaris luxadm Utility
The luxadm program is a command-line management utility for administering the
Sun Fire V890 internal Fibre Channel-Arbitrated Loop (FC-AL) storage subsystem
and supported external storage arrays. You use luxadm to perform physical disk
management tasks, including disk hot-plug operations. The luxadm utility is
installed automatically when you install the Solaris OS.
The luxadm utility performs a variety of control and query tasks through a number
of subcommands and command-line options. Using luxadm, you can:
■ Assign a convenient enclosure name to the Sun Fire V890 internal storage array
■ Display the physical and logical device paths, world wide names (WWNs), and
enclosure names for storage arrays and individual disks
■ Display configuration, environmental, and status information for any array or
individual disk
■ Reserve a specific disk for exclusive use by a single host
■ Perform hot-plug insertion or removal of disks
■ Download firmware and fcode updates for mass storage components
Note – Setting the front panel keyswitch to the Locked position prevents
reprogramming of system firmware. If the keyswitch is turned to the Locked
position after a firmware update operation has started, the operation is allowed to
proceed to completion. For more information about the front panel keyswitch, see
“About the Status and Control Panel” on page 11.
