where <device> is the name of the device node (/dev/fctx), where x indicates the device number: 0,
1, 2, and so on. For example, /dev/fct0 indicates the first IO Accelerator device installed on the system.
Options Description
-b <size
B|K>
Set the block (sector) size, in bytes or KiBytes (base 2). The default is 512 bytes. For
example: -b 512B or -b 4K (B in 512B is optional).
-f Force the format size, bypassing normal checks and warnings. This option may be
needed in rare situations when fio-format does not proceed properly. (The "Are you
sure?" prompt still appears unless you use the -y option.) This option can only be used
with the -o option.
-q Quiet mode: Disable the display of the progress-percentage indicator.
-s <size
B|K|M|G|T|%>
Set the device capacity as a specific size (in TB, GB, or MB) or as a percentage of the
advertised capacity:
• T Number of terabytes (TB) to format
• G Number of gigabytes (GB) to format
• M Number of megabytes (MB) to format
• % Percentage, such as 70% (The percent sign must be included)
-o <size
B|K|M|G|T|%>
Over-format the device size (to greater than the preset capacity), where the maximum
size equals the maximum physical capacity. If a percentage is used, it corresponds to
the maximum physical capacity of the device. (Size is required for the -o option; see
the -s option above for size indicator descriptions.)
Before using this option, for supported recommendations, contact HP Support
( http://www.hp.com/support )
-r Enable fast rescan on non-ordered shutdowns at the cost of some capacity.
-y Auto-answer "yes" to all queries from the application (bypass prompts).
fio-pci-check
Description
Checks for errors on the PCI bus, specifically for IO Accelerators. This utility displays the current status of each
IO Accelerator. It also prints the standard PCI Express error information and resets the state.
It is normal to see a few errors (perhaps as many as five) when fio-pci-check is initially run. Subsequent
runs reveal only one or two errors during several hours of operation.
Syntax
fio-pci-check [options]
Options Description
-d <value> 1 = Disable the link; 0 = enable the link (Not
recommended)
-f Scan every device in the system
-i Print the device serial number. This option is invalid when
the IO Accelerator is loaded.
-r Force the link to retrain
-v Verbose: Print extra data about the hardware
