To delete all migrated datasets from Tapes

hi all,

i need to do a region refresh. there are around 36000 datasets.
most of them are in migrated status. i need to delete a set of datasets that are in the migrated status migration level2(tape migrated). is there any way i can delete these migrated datasets(ex zjpvpj2.td**) using a single command on the command line or any jcl which does this fuction.

please let me know for any clarifications.

Regards,
Pavan

Pavan,

For deleting datasaets(Test/Production) you need to have the permission to do that?

I beleive you need to check out with your system programmers.

Let me know why you need to delete them ? Since all the datasets are migrated, you wont encounter any problem.

Hi diwa,

thanks for the reply. i do have the access to delete the datasets.
we are doing the region refresh of the test region because there is a lot of junk data present in this test region(lot of unecessary tape resource used). moreover we are trying to simulate it with the production region data and carry out testing in this region, thts the reason we are deleting the data in this particular region

Regards,

Pavan,

I beleive we cannot delete migrated tape datasets.

You need to check with your system programmers to do tat.

Hi,
This can be done using group of ISPF commands
1. Use the first qualifier/ or the qualifier datasets you are looking for in 3.4
2. Issue "SAVELIST ABC", all the datasets will be stored in one dataset.
3. By using Edit commands, IDCAMS you can delete the migrated datasets

Thanks

Hi Diwa,
i got it ...just written a JCL which would delete the migrated datasets at a single go..

thanks for the responses

Expat,

In my environment, we do not have permission to delete the datasets which got migrated to TAPE.

If it is archieved ,we can restore and delete, but we do not have access the tape .

So i thought only sytem programmers might have access to delete.

Murali,

That is the access level given to the programmers to safeguard production data. We cannot comment on that.

You can always the delete the dataasets created under your ID.

You do not need access to the tape to delete a migrated dataset.

Try HDEL next to the dataset ( assuming HSM is your ILM ) and see what happens. Also IDCAMS will delete a migrated dataset without need for recall.

I wonder if the dataset is migrated to tape or any offline volume, then we can delete it without actually mounting that volume/tape.
I think the catalog entry will be deleted in this case, but the data will be still there on tape/volume.

Thanks,
Ganesh

Yes, the data would remain on the tape until the tape was recycled. It is possible to sometimes recover a deleted ML2 dataset, before recyling has been processed, although if the ML2 / backup relationship is properly planned not usually required.

Something I have recently discovered is that there are different levels of RACF protection for HDEL and HSEND DELETE, with HDEL normally being generally available, but HSEND DELETE has a completely different RACF profile to protect it and is usually only available to storage admin. Wierd eh ?

Hi Pavan,

I am also searching for an option to delete the migrated GDG generations.

Please let me know how you have done that.

Why resurrect a 5 year old topic.
Search the forum.
