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 useful manners 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-pci-check

Searches for errors on the PCIe bus tree, specifically for

 

PCIe IO Accelerators

fio-snmp-agentx

SNMP subagent that implements the SNMP

 

FUSION-IODRV-MIB for the IO Accelerator

fio-status

Displays information about the device

fio-sure-erase

Clears or purges data from the device

fio-update-iodrive

Updates the IO Accelerator firmware

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

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.
