Re: Copy DSS Dump File to DASD
Todd, this is not a stupid suggestion at all. Many (most?) of these data sets contain back up copies of existing VSAM datasets, so restoring them without a rename would be a problem, unless I: - restore them to my test system (no shared catalogs) - rerun DSS back up on test system, with output to DASD - Run DSS COPYDUMP on prod system to create final SMS managed backup GDG It would be like going all the way around the block to get next door, so I wouldn't want to do this for all the data sets getting converted from Tape to DASD, but for those 24 generation monthly / quarterly / yearly ones, it just might be worth the effort to free up the tapes. The other tapes will free up on their own soon enough. Thanks! Tom Chicklon This may be a stupid suggestion, but why not just restore the data to spare volume(s), and then recreate the dump on disk with the same dataset name as the current tape (rerun the dump)? Since the COPYDUMP command does not seem to be a good option, I'd just try to recreate the dump in another way if it was that important to move it. C.

Re: Copy DSS Dump File to DASD
Thanks for the confirmation Andrew, this is as I suspected. I guess we'll just have to wait for the tape data sets to roll off (they are all GDGs).

Re: Copy DSS Dump File to DASD
You may use TV (Tape to VSAM) function of DITTO/ESA. If the tape block size is less than 32760 bytes, you can use TS (Tape to Sequential data) function. When you define the VSAM ESDS for over 32K tape block size, you have to specify SPANNED parameter and large number of RECORDSIZE that fit the tape block size. 2007/7/6, Chicklon, Tom <[EMAIL PROTECTED]>: I think I'm out of luck, but wanted to verify first. We're z/OS 1.7. We've had a number of small DSS DUMP files written to tape that I want to move to DISK. Unfortunately, it seems that the dump files on tape get created with a block size of about 64K, and from the DSS manual: The COPYDUMP command cannot change the block size of the DFSMSdss dump data set. If you are copying a dump data set to a DASD device, the source block size must be small enough to fit on the target device. Is there no way to copy these DSS dump files to disk other than restoring the files (renaming them of course) and backing them up again?
