The Question is:
Does VMS 7.1 support a tapedrive with QIC 157 standard?
If not, Does 7.2 support this?
The Answer is :
QIC-157 is an interface specification for ATAPI/IDE-based Quarter
Inch (QIC) tape drives.
The OpenVMS Wizard is unaware of any ATAPI/IDE peripheral support
(disks, tapes, or otherwise) for VAX systems, though third-party
options might exist.
OpenVMS typically operates with various SCSI-based tape drives and
other SCSI peripherals, including QIC, DDS, DLT, 9-track 1600/6250
BPI, and other tapes. (In the case of QIC tapes, also assuming that
the device supports variable block mode operations.)
As for SCSI QIC tape drives, Tru64 UNIX interchange with OpenVMS via
QIC is most common with the ltf utility.
The officially supported QIC drives are in the TZK1x family -- these
are known to work. These devices are obviously SCSI, not ATAPI/IDE.
The OpenVMS Alpha ATAPI (IDE) interface is the DQDRIVER, and this
device driver is not currently configured as a class and port driver.
This means that any attempt to connect tapes will end up using at least
some disk-derived semantics, and there is currently no easy way to
connect a tape-oriented class driver onto an ATAPI/IDE port driver.
While nothing has been done to specifically preclude operations of
tapes, no testing and no support presently exists for ATAPI tapes.
