operations. This parameter can be used with all test
flags.
−err_lines
Specifies the maximum number of error messages
that are produced as a result of an individual test.
A limit on error output prevents a large number of
diagnostic messages if persistent errors occur. This
parameter can be used with all test flags.
−minutes
Specifies the number of minutes to test. This
parameter can be used with the −r and −w test flags.
−max_xfer
Specifies the maximum transfer size to be
performed. If transfers are done using random
sizes, the sizes are within the range specified by the
−max_xfer and −min_xfer parameters. If fixed
size transfers are specified (see the −F flag),
transfers are done in a size specified by the
−min_xfer parameter.
Specify transfer sizes to the character special file in
multiples of 512 bytes. If the specified transfer size
is not an even multiple, the value is rounded down
to the nearest 512 bytes. This parameter can be
used with the −r and −w test flags.
−min_xfer
Specifies the minimum transfer size to be
performed. This parameter can be used with the −r
and −w test flags.
−num_xfer
Specifies the number of transfers to perform before
changing the partition that is currently being
tested. This parameter is only useful if more than
one partition is being tested. If this parameter is not
specified, the number of transfers is set to a number
that completely covers a partition. This parameter
can be used with the −r and −w test flags.
−o
filename
Sends output to the specified file name. The default
is to display output on the terminal screen. This
parameter can be used with all test flags.
