SG_READ_BLOCK_LIMITS(8) SG3_UTILS SG_READ_BLOCK_LIMITS(8) NAME sg_read_block_limits - send SCSI READ BLOCK LIMITS command SYNOPSIS sg_read_block_limits [--help] [--hex] [--mloi] [--raw] [--readonly] [--ver- bose] [--version] DEVICE DESCRIPTION Send a SCSI READ BLOCK LIMITS command to DEVICE and outputs the response. This command is defined for tape (drives) and its description is found in the SSC documents at https://www.t10.org . OPTIONS Arguments to long options are mandatory for short options as well. -h, --help output the usage message then exit. -H, --hex output response in hex (rather than decode it). -m, --mloi sets the MLOI bit in the READ BLOCK LIMITS command and if that suc- ceeds, prints out the Maximum Logical Object Identifier (MLOI) value. The MLOI bit was introduced in the ssc4r02.pdf draft. -r, --raw output response in binary to stdout. -R, --readonly open DEVICE in read-only mode. The default is to open it in read-write mode. -v, --verbose increase the level of verbosity, (i.e. debug output). -V, --version print the version string and then exit. EXIT STATUS The exit status of sg_read_block_limits is 0 when it is successful. Other- wise see the sg3_utils(8) man page. EXAMPLES It is usually okay to use no options. Here is an invocation (on the first line following the "#" command prompt) followed by some typical output: # sg_read_block_limits /dev/st0 Read Block Limits results: Minimum block size: 1 byte(s) Maximum block size: 16777215 byte(s), 16383 KB, 15 MB Granularity: 0 AUTHORS Written by Douglas Gilbert.
