M2488 PRODUCT GUIDE TAPE UNIT SCSI COMMANDS
April 1997 CG00000-011503 REV. A 4-73
** NOTE **
1. A buffer may be altered between the WRITE BUFFER and READ
BUFFER commands by execution of commands from another initiator
or background diagnostics. Buffer testing applications may avoid
buffer usage conflicts with other initiators by use of linked command,
or by reserving the addressed LUN.
2. There is only one 512-byte NVRAM area available. This area may
be accessed by any initiator. The NVRAM is not partitioned into “per
initiator” areas.
