2227.0. "Fast Tape Positioning" by STOWKS::SLUIS (Hans van Sluis -- Storage Engineering Support Europe- DTN 889 9526) Mon Mar 24 1997 03:01
COPY OF STKHLM::MAGTAPE NOTE 3902
Fast Tape Positioning on DLT drives
===================================
This tool allows system managers to 'skip' directly to the tape position
where their data resides. This tool can be used in places where a
$SET MAGTAPE <Device> /SKIP=FILES=n is used. It is based on
proven code in the HSM for OpenVMS product.
This tool has proven to work on :
- HSJ & HSD connected TZ8x drives
- MSCP-served TZ8x-drives
- Local connected SCSI TZ8x drives
The used version of the Operating System was OpenVMS V6.2 (both VAX and
Alpha). However, recompilation on OpenVMS V6.1 will get this tool to work.
To be able to build this tool, you'll need :
- 1500 blocks of disk space
- A C-compiler (DEC C)
- 5 minutes or less, just to issue a [email protected]
The usage of this tool is as follows :
1) fasttape :== "$DISK$USER:[YOUNAMEIT.ALPHA]FASTTAPE.EXE" or
fasttape :== "$DISK$USER:[YOUNAMEIT.VAX]FASTTAPE.EXE"
2) fasttape -device <Device> -p <Required Position>
This tool can be given to customers without any support.
