Fred, Unlike the MVS/Catalog were CA-1 will un-catalog the file as it goes scratch, with HSM CA-1 will NOT tell HSM that a tape has gone scratch and should be removed from the CDS; it is the other direction. HSM notifies CA-1 when a tape can be released and put back into the scratch pool. Since HSM believes these tapes are scratch, then HSM notified CA-1 and CA-1 scratched the tapes. It sounds like something was changed within HSM so that it believed it only needed a smaller number of duplex tapes and released the extra's.

We are a bit nervous about releasing them for scratch, since they are HSM migration tape duplex copies and we don't see the original tape of the duplex pair in this list. We expected that both tapes of a duplex pair would be marked scratch at the same time. We would like to identify some datasets on these tapes and check that they really do no longer exist as catalog entries with VOLSER of MIGRAT* on the system. Unfortunately, as far as HSM is concerned, the tapes are now marked as scratch. This means we cannot do a LIST TTOC for these volumes in the OCDS to see what datasets are on the tape. We also cannot identify what the VOLSER is of the other volume in the duplex pair. Tape utilities to list the tape's contents seem to be a waste of time, as there is only one dsname on the tape, ie HSM.COPY.HMIGTAPE.DATASET and the actual data is in a compressed form. We ran a HSM audit to see if that gave us a warm fuzzy feeling. We saw lots of "FIX ATTEMPT - BAD TTOC SUCCESSFUL", but no VOLSER's were mentioned in the output. This also makes us nervous. Some manual changes to CA1's OUTCODE for various tapes were made prior to the increase in the scratch tape list. But we are not sure if this is related to the problem. HSM gurus.... help! Please. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
