Do a normal mount of the tape (i.e. leave off the /FOREIGN and supply the volume label) and get a directory listing of the tape using your standard DCL directory command. Just like disk based save sets, you will find the file names are your save set names. -Ron-

Yes, just do $ BACKUP /LIST MUA0:* Another hint: $ BACKUP /LIST=NLA0: MUA0:* is a good way to test if your backup tape is readable (at least) without having to do a /VERIFY due to time constraints. However, even BACKUP /LIST isn't terribly fast. = Frank J.

I appreciate your remarks concerning BACKUP. Indeed, due to all the replies I have received, I have learned a good deal about the parameters associated with BACKUP. This has led me to a broader question: Is it possible to manage tapes sensibly on VMS? I used a CDC Cyber for many years and I cannot find anything under VMS to approach the LABEL command under NOS. In general, I am concerned about the issue of security and device allocation and deallocation. Have you addressed these issues in your shop, or do you know of anything on the DECUS tapes or commercially available that addresses this issue? Thanks for your help Frank Simmons

I used a CDC Cyber for many years and I cannot find >anything under VMS to approach the LABEL command under NOS. The answer to your question is "no". MTAACP seems to be designed for a shop consisting of four or five guys who are friendly and cooperative, and have offices or workbenches in the same room with the machine. Cyber gurus aren't the only ones who find VMS lacking in this area: our site also runs a DECSYSTEM20 whose labelled-tape subsystem is five to ten years ahead of VMS'. > In general, I am >concerned about the issue of security and device allocation and deallocation. You should be: anybody can override tape label "security" at any time. We take the approach used by a certain other vendor: we just don't tell our users how to do it. >Have you addressed these issues in your shop, or do you know of anything >on the DECUS tapes or commercially available that addresses this issue? I wish I did. The extent of our efforts here has been to build a (rather hokey) tape staging system that feeds our backup jobs. (It would be interesting to know why BACKUP seems purposely designed *not* to be able to run reliably in batch. System backup is *not* an interactive task.) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ The good news is that there are believable rumors of significant improvement in tape handling for a future unmentionable release. I have heard that a tape management system will be available as a layered product, and our site is waiting impatiently to see what it turns out to be. The rumors also speak of improvements in the base system, including BACKUP. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Mark H.
