"There is another requirement here: to read REAL tape using PC tools. How to read? a) dataset by dataset b) whole tape => AWS tape image"
Radoslaw, Hercules has a really cool utility called TAPECOPY! It reads a real tape and copies it to an AWSTAPE format disk file. Of course, being written by mainframes, TAPECOPY is sensitive to mainframe tape marks, RDW/BDW, etc. The resulting AWSTAPE file is a mirror image of the tape. "The Hercules tape copy program copies a SCSI tape to or from an AWSTAPE disk file. Tapecopy reads a SCSI tape and outputs an AWSTAPE file representation of the tape, or reads an AWSTAPE file and creates an identical copy of its contents on a tape mounted on a SCSI tape drive. If the input file is a SCSI tape it is read and processed until physical EOD (end-of-data) is reached. That is, it does not stop whenever multiple tapemarks or filemarks are read, rather it continues processing until the SCSI tape drive says there is no more data on the tape. The resulting AWSTAPE output disk file may be specified for the filename on a Hercules tape device con- figuration statement. It can then be used in order for the Hercules guest O/S to read the exact same data without having a SCSI tape drive physically attached to the host system. This allows you to easily transfer SCSI tape data to other systems that may not have SCSI tape drives attached to them."
