sg_turs - executes a user specified number of TEST UNIT READY commands
on the given device
sg_turs [-n=<number of commands to send>] [-t] [-v] [-V] <scsi_device>
sg_turs sends a number of TEST UNIT READY commands to a given SCSI
device. Useful for timing the per command overhead. Note that TEST UNIT
READY has no associated data, just a 6 byte command and a returned SCSI
performs TEST UNIT READY "<num>" times. If not given defaults to
1. These suffix multipliers are permitted: c C *1; w W *2; b B
*512; k K KiB *1,024; KB *1,000; m M MiB *1,048,576; MB
*1,000,000; g G GiB *1,073,741,824; and GB *1,000,000,000 . Also
a suffix of the form "x<n>" multiplies the leading number by
<n>. Alternatively a hex number may be given, prefixed by either
0x or 0X.
-t after completing the requested number of TEST UNIT READY
commands, outputs the total duration and the average number of
commands executed per second.
-v increase level of verbosity: print out SCSI commands in hex
prior to sending them to the device. ’-vv’ and ’-vvv’ are also
accepted yielding greater verbosity.
-V print out version string then exit.
