HP IO Accelerator for BladeSystem c-Class - Manual (Page 45)

Utilities 45
Option Default
(min/max)
Description
After the affinity is queried correctly, the driver sets
the affinity of the adapter interrupt and associated
worker threads to the default operating system
setting. This action has the effect of setting the
affinity of the interrupt and worker threads to all
processors on a single NUMA node in the system.
When WIN_DISABLE_DEFAULT_NUMA_AFFINITY
is set to 1, the driver will ignore the affinity settings
assigned to the adapter by the OS. The driver must
be reloaded for this parameter to take effect.
FIO_AFFINITY N/A FIO_AFFINITY is a list of <affinity
specification> triplets to specify the affinity
settings of all adapters in the system. Each item in
the triplet is separated by a comma, and each
triplet set is separated by a semicolon. For more
information on using this parameter, see "NUMA
configuration (on page 67 )."
fio-detach
Description
Detaches and removes the corresponding /dev/fctx IO Accelerator block device. The fio-detach
command waits until the device completes all read/write activity before executing the detach process. The
command displays a progress bar and percentage as it completes the process.
NOTE: Before using this utility, be sure that the device you want to detach is not currently
mounted and in use.
Syntax
fio-detach <device> [options]
where <device> is the name given to the IO Accelerator during the installation process. The syntax is
/dev/fctx, where x indicates the PCIe bus number where you installed the IO Accelerator. For example,
the name /dev/fct4 refers to the IO Accelerator device installed in PCIe Bus 4 in your Windows®
operating system. To view this bus number, use the IO Accelerator Management Tool or fio-status.
You can specify multiple IO Accelerator devices. For example, /dev/fct1 /dev/fct2 indicates the
devices installed in PCIe Buses 1 and 2 in your Windows® operating system.
Options
Option Description
-f Force: Causes an immediate detach (does not save metadata).
-i Immediate: Causes a forced immediate detach (does not save metadata). This will fail if the device
is in use by the OS.
-q Quiet: Disables the display of the progress bar and percentage.
