HP IO Accelerator for BladeSystem c-Class - Manual (Page 26)

Utilities 26
Options Description
-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-status
Description
Provides detailed information on installed devices. This utility operates on either fctx or fiox devices. The
utility runs from root level and having the IO Accelerator loaded. If no IO Accelerator is loaded, there is less
content reported from the query.
Enabling fio-status provides alerts for certain error modes, such as a minimal-mode, read-only mode,
and write-reduced mode, describing what is causing the condition.
Syntax
fio-status [<device>] [<options>]
where <device> is the name of the device node (/dev/fctx), where x indicates the card number: 0, 1,
2, and so on. For example, /dev/fct0 indicates the first IO Accelerator device installed on the system.
If <dev> is not specified, fio-status displays information for all cards in the system. If the IO Accelerator
is not loaded, this parameter is ignored.
Options Description
-a Report all available information for each device.
-e Show all errors and warnings for each device. This option is for diagnosing issues, and
it hides other information such as format sizes.
-c Count: Report only the number of IO Accelerator devices installed.
-d Show basic information set plus the total amount of data read and written (lifetime data
volumes). This option is not necessary when the -a option is used.
-fj Format JSON: creates the output in JSON format.
-fx Format XML: creates the output in XML format.
