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 -yoption.) This option can only be used

 

with the -ooption.

-q

Quiet mode: Disable the display of the progress-percentage indicator.

 

 

-s <size

Set the device capacity as a specific size (in TB, GB, or MB) or as a percentage of the

BKMGT%>

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

Over-format the device size (to greater than the preset capacity), where the maximum

BKMGT%>

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 -ooption; see

 

the -soption above for size indicator descriptions.)

-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-statusprovides 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-statusdisplays 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 -aoption is used.

 

-fj

Format JSON: creates the output in JSON format.

 

-fx

Format XML: creates the output in XML format.
