[--wrap-offset=WO] DEVICE
where:
--10|-T do PRE-FETCH(10) command (def: SEEK(10), or
PRE-FETCH(16) if --pre-fetch also given)
--count=NC|-c NC NC is number of commands to execute (def: 1)
--grpnum=GN|-g GN GN is group number to place in PRE-FETCH
cdb; 0 to 63 (def: 0)
--help|-h print out usage message
--immed|-i set IMMED bit in PRE-FETCH command
--lba=LBA|-l LBA starting Logical Block Address (LBA) (def: 0)
--num-blocks=NUM|-n NUM number of blocks to cache (for PRE-FETCH)
(def: 1). Ignored by SEEK(10)
--pre-fetch|-p do PRE-FETCH command, 16 byte variant if --10 not
given (def: do SEEK(10))
--readonly|-r open DEVICE read-only (if supported)
--skip=SB|-s SB when NC>1 skip SB blocks to next LBA (def: 1)
--time|-t time the command(s) and if NC>1 show usecs/command
(def: don't time)
--verbose|-v increase verbosity
--version|-V print version string and exit
--wrap-offset=WO|-w WO if SB>0 and WO>0 then if LBAn>LBA+WO
then reset LBAn back to LBA (def: 0)
Performs SCSI SEEK(10), PRE-FETCH(10) or PRE-FETCH(16) command(s).If no
options are given does one SEEK(10) command with an LBA of 0 . If NC>1
then a tally is kept of successes, 'condition-met's and errors that is
printed on completion. 'condition-met' is from PRE-FETCH when NUM blocks
fit in the DEVICE's cache.
Options (14)
| Option | Description | Source |
|---|
--count, -c NC|-c | NC is the number of commands (one of SEEK(10), PRE-FETCH(10) or PRE-FETCH(16)) that will be executed. | help + man |
--grpnum, -g GN|-g | GN is the group number, a value between 0 and 63 (in hex: 0x3f). | help + man |
--lba, -l LBA|-l | LBA is the starting logical block address that is placed in the command descriptor block (cdb) of the selected command. | help + man |
--num-blocks, -n NUM|-n | NUM is the number of blocks, starting at and including LBA, to place in the DEVICE's cache. | help + man |
--skip, -s SB|-s | SB is the number of logical block addresses to skip, between repeated commands when NC is greater than 1. | help + man |
--wrap-offset, -w WO|-w | WO is the number of blocks, relative to LBA, that when exceeded, set the next command's logical block address back to LBA. | help + man |
-T, --10 | use a 10 byte cdb command, either SEEK(10) or PRE-FETCH(10) command. (in the manual page but not in --help) | man |
-h, --help | output the usage message then exit. (in the manual page but not in --help) | man |
-i, --immed | this option only applies to PRE-FETCH(10) and PRE-FETCH(16), setting the IMMED bit. (in the manual page but not in --help) | man |
-p, --pre-fetch | this option selects either PRE-FETCH(10) or PRE-FETCH(16) commands. (in the manual page but not in --help) | man |
-r, --readonly | this option sets a 'read-only' flag when the underlying operating system opens the given DEVICE. (in the manual page but not in --help) | man |
-t, --time | if given the elapsed time to execute NC commands is recorded. (in the manual page but not in --help) | man |
-v, --verbose | increase the level of verbosity, (i.e. debug output). (in the manual page but not in --help) | man |
-V, --version | print the version string and then exit. (in the manual page but not in --help) | man |
