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.
