Invoking fx From IRIX

1. Make sure that the disk drive to be partitioned is not in use. That is, make sure that no filesystems are mounted and no programs are accessing the drive.

2. As superuser, give the fx command:

   # fx "controller_type(controller,address,logical_unit)"

   The variables are:

   controller_type

   The controller type. It is dksc for SCSI controllers. For other controller types, see the fx(1M) reference page.

   controller

   The controller number for the disk.

   address

   The drive address of the disk.

   logical_unit

   The logical unit number for the device. It is used by only a few SCSI devices such as RAIDs (an array of disks with built-in redundancy) to address disks within the device. The logical_unit is normally 0.

   If you give the q

   command without arguments, you are prompted for these values.

   fx first performs a controller test, then displays this menu:

---- please choose one (? for help. .. to quit this menu)----
[exi]t               [d]ebug/                [l]abel/
[b]adblock/          [exe]rcise/             [r]epartition/
fx>

The exit option quits fx, while the other commands take you to submenus. (The slash [/] character after a menu option indicates that choosing that option leads to a submenu.) For complete information on all fx options, see the fx(1M) reference page.
