Hi folks, We are in the process of migrating from 3590 to 3592 tape. We would like to use HSM's Tape Mount Management (TMM) to stack data on the new tapes, thus taking advantage of their much greater capacity.
However, much of the data we have on 3590 tape currently is backups in DFDSS DUMP format with a blocksize of 229360 (LBI). The fine DFDSS manual says that COPYDUMP is the only supported method for copying DUMP datasets, and that it cannot be used to change the blocksize of the DUMP dataset. This means that we cannot copy this data from tape to DASD as it does not support block sizes larger than 32760. Therefore we cannot copy it to TMM. I have considered restoring the datasets in these dumps and then re-dumping them to TMM. However, since the datasets in the dumps largely still exist, they would have to be restored to a non-SMS volume as uncataloged datasets. Given that we have some 22,000 datasets on tape and a lot of them are DFDSS DUMP's, that is starting to look very ugly. So, does anybody have a more practical approach?
