Utilities reference

The IO Accelerator installation packages include various command line utilities, installed by default to the /usr/bin file. These utilities provide a number of ways to access, test, and manipulate your device.

Utility	Purpose
fio-attach	Makes an IO Accelerator available to the OS
fio-beacon	Lights the IO Accelerator external LEDs
fio-bugreport	Prepares a detailed report for use in troubleshooting issues
fio-detach	Temporarily removes an IO Accelerator from OS access
fio-format	Used to perform a low-level format of an IO Accelerator
fio-status	Displays information about the device
fio-update-iodrive	Updates the IO Accelerator firmware

NOTE: All utilities have –h (Help) and –v (Version) options.

To set IO Accelerator VSL parameters, edit the iomemory-vsl.conffile: (/usr/kernel/drv/iomemory-vsl.conf)

fio-attach

Description

Attaches the IO Accelerator device and makes it available to the operating system. This creates a block device in /dev named fiox (where x is a, b, c, and so on). Then, you might partition or format the IO Accelerator device, or set it up as part of a RAID array. The command displays a progress bar and percentage as it operates.

NOTE: In most cases, the IO Accelerator automatically attaches the device on load and does a scan. You only have to run fio-attachif you ran fio-detachor if you set the IO Accelerator auto_attach parameter to 0.

Syntax

fio-attach <device> [options]

where <device> is the name of the device node (/dev/fctx), where x indicates the card number: 0, 1, 2, and so on. For example, /dev/fct0 indicates the first IO Accelerator device installed on the system.

You can specify multiple IO Accelerator devices. For example, /dev/fct1 /dev/fct2 indicates the second and third IO Accelerator devices installed on the system. You can also use a wildcard to indicate all IO Accelerator devices on the system.

For example, /dev/fct*
