HP PCIe IO Accelerator for ProLiant Servers

Appendix C: Utilities Reference 35
fio-detach
Description
Detaches the PCIe IO Accelerator and removes the corresponding
fctx PCIe IO
Accelerator block device from the OS. The
fio-detach utility waits until the device
completes all read/write activity before executing the detach operation. The
command also displays a progress bar and percentage as it completes the process.
NOTE: Before using this utility, ensure that the device you want to detach is not currently
mounted and in use.
Syntax
fio-detach <device> [-i, -q, -h, -v]
where <device> is the name given by the PCIe IO Accelerator driver to your device.
This name is
/dev/fctx, where x indicates the device number. (The number reflects
the PCIe bus for the PCIe IO Accelerator.) For example, the name
/dev/fct4 refers to
the PCIe IO Accelerator installed in PCIe Bus 4 in your system. (Use
fio-status to
view this number.)
Options
-i Immediate: Causes a forced immediate detach (does not save metadata)
-q Quiet: disables the display of the progress bar and percentage.
fio-format
Description
Performs a low-level format of the PCIe IO Accelerator. (This format is distinct from a
format performed by the operating system.) The utility displays a progress bar and
percentage as it completes the format.
NOTE: The PCIe IO Accelerator ships pre-formatted and does not require the use of
fio-
format except to change the logical size of the device.
CAUTION: Use this utility with care, as it deletes all user information on the PCIe IO
Accelerator.
