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-attach if you ran fio-detach or if you set the IO Accelerator

auto_attach parameter to 0.

Syntax
fio-attach [options]
where 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*
