January 13, 1998 Robin Miller
The following changes have been made to 'dt' Version 11.2:
o Support for tape Extended Error Information (EEI) and SCSI bus
or device reset recovery has been added (to reposition the tape).
The EEI support is enabled by default, but the reset support is
disabled by default (to avoid breaking existing test scripts).
The reset option can also be used w/POSIX Asynchronous I/O (AIO).
NOTE: EEI support is Digital UNIX specific (MTIOCGET extension).
[ Use the "enable/disable={eei,resets}" option to control these. ]
o The logical block data feature, "enable=lbdata" option, has been
extended so it can be used with random I/O, "iotype=random" option.
What is 'lbdata' option?
'lbdata' places the block number in the 1st 4 bytes of each block,
which gets verified during the read pass. In the case of disks,
the lbdata is stored in each sector, normally every 512 bytes.
This uniqueness works well for random I/O with overwrites, but
works equally well for any data stream (it's not device specific).
o Two new options were added for better range control of random I/O.
The "ralign=value" option forces block alignment to a byte offset.
For example, "ralign=32b" aligns each random request to 32 blocks.
The "rlimit=value" option contols the upper random I/O data limit.
If rlimit isn't specified, it defaults to the data limit, or to the
entire disk if no limits are specified.
o Changes to cluster DLM code were merged from work by George Bittner.
George also enhanced the random I/O code so the random number is
taken as a block, rather than a byte offset, which provides better
randomness for large disks or files. (Thanks George!)
o Other changes and/or bug fixes:
- When specifying a runtime, ensure we break out of the passes loop
if we exceed the error limit. Previously, we'd loop (possibly with
error) for the duration of runtime.
- Fix incorrect record number displayed when Debug is enabled.
- Don't exit read/write loops when processing partial records.
- Fix problem in write function, where short write processing,
caused us not to write sufficent data bytes (actually, the
file loop in write_file() caused dtaio_write_data() to be
called again, and we'd actually end up writing too much!
- When random I/O and lbdata options are both enabled, use the
file offset seeked to as the starting lbdata address.
- Fix problem reporting total files processed count when we have
not completed a pass (exiting prematurely due to error or signal).
o 'dt' compiles and runs on MS Windows 95/98/NT using Cygwin tools.
Use Makefile.win32 for compiling on Windows.
[ a.k.a. GNU-Win32, URL: http://sourceware.cygnus.com/cygwin/ ]
o When directing output to a log file, "log=LogFile" option, the
command line and version string are also emitted. Example:
Command Line:
% dt of=/dev/rmt0h bs=64k limit=10m aios=16 files=2 enable=lbdata,resets log=resets.log
