These command-line utilities provide a number of useful ways to access, test, and manipulate the HP

–h and –v options are available for all of the utilities. Unless specified otherwise, the –h option is for
help, and the –v option is for version information.
fio-attach
Attaches a block device node to a pre-formatted HP StorageWorks IO Accelerator. This utility creates
a block device in /dev, named "fiox" (where x is a, b, c, etc. in Linux or a disk device in Windows),
which can be used raw, partitioned or filled with a filesystem.
Before you use this utility, the board must have already been formatted using the fio-format utility (the
IO Accelerator board comes pre-formatted, so generally it's not necessary to use this utility unless you
need to reformat the drive for performance reasons; also note that the fio-format utility performs a
low-level format that is not the same as doing a format on a file system using standard disk management
utilities). After that, fio-attach makes the file system available to the OS.
NOTE:
In most cases, the driver automatically attaches the device on load, so fio-attach does not need to be
invoked. If a manual format has been done, or if the auto_attach=0 parameter is given to the kernel
module at load time, then you need to run fio-attach to create the block device.
fio-attach <device-node> –q
<device-node>
Device node for the HP StorageWorks IO Accelerator board (/dev/fctx), where x indicates the board
number (0, 1, 2, etc). For example: /dev/fct0-q Quiet option. Disables progress status.
