where:

--ck_cond | -C set ck_cond field in pass-through (def: 0)
--count=CO | -c CO count of page numbers to fetch (def: 1)
--dma | -d Use READ LOG DMA EXT (def: READ LOG EXT)
--help | -h output this usage message
--hex | -H output response in hex bytes, -HH yields hex
words + ASCII (def), -HHH hex words only
--len=CDB_LEN | -l CDB_LEN cdb length: 12, 16 or 32 bytes (def: 16)
--log=LA_L | -L LA_L Log address, log address range or list of ...
See below for syntax
--page=PN|-p PN Log page number within address (def: 0)
--ppt=PPT|-P PPT pages per transfer (def: 64)
--readonly | -r open DEVICE read-only (def: read-write)
--smart | -s send the ATA SMART READ LOG command instead
--verbose | -v increase verbosity
recommended if DEVICE is ATA disk
--version | -V print version string and exit
Sends an ATA READ LOG (DMA) EXT or a SMART READ LOG command via a SAT
pass-through to fetch one or more General Purpose (GP) or SMART log pages.
Each page is accessed via a log address (LA) and then a page number
within that address. Multiple log addresses can be given in the LA_L
argument to the --address= and --log= options. It may contain a comma
separated list with each element either being a single LA or a range with
this format: 'lo:hi'. LA_R syntax summary: lo:hi,lo2:hi2,lo3:hi3,...
Options (14)
| Option | Description | Source |
|---|
--address, -a LA_L | where LA_L is as single "log address", a range of log addresses, or a list of (ranges of) log addresses. | help + man |
--ck_cond, -C | sets the CK_COND bit in the ATA PASS-THROUGH SCSI cdb. | help + man |
--count, -c CO | the number CO is placed in the "count" field in the ATA READ LOG EXT command. | help + man |
--dma, -d | use the ATA READ LOG DMA EXT command instead of ATA READ LOG EXT command. | help + man |
--help, -h | outputs the usage message summarizing command line options then exits. | help + man |
--hex, -H | output response in hex bytes, -HH yields hex words + ASCII (def), -HHH hex words only | help + man |
--len, -l CDB_LEN | where CMD_LEN is the command (cdb) length of the SCSI ATA PASS-THROUGH command that is used to tunnel ATA commands. | help + man |
--log, -L LA_L | Log address, log address range or list of ... | help + man |
--page, -p PN|-p | the number PN is the page number (within the log address) and is placed in bits 32:16 of the "lba" field of the ATA READ LOG (DMA) EXT command. | help + man |
--ppt, -P PPT|-P | where PPT is the number of pages to transfer from the DEVICE per ATA READ LOG EXT or an ATA READ LOG DMA EX command invocation. | help + man |
--readonly, -r | causes the DEVICE to be opened with the read-only flag (O_RDONLY in Unix). | help + man |
--smart, -s | in the ATA SMART feature set, "SMART" log pages have been present for a long time and pre-date the later addition of the "general purpose" log pages. | help + man |
--verbose, -v | increase verbosity recommended if DEVICE is ATA disk | help + man |
--version, -V | print version string and exit | help + man |
