How to decrypt all the data sets on the CA Disk Archive and Backup Tape volumes?
Environment
Component:
Resolution
Set up CA Disk MERGE to read the encrypted tapes and write them non-encrypted to another tape device type.
The customer created a listing of all Archived and Backup Tape volumes in use and verified the following process:
1) Dump the header to determine if it is an encrypted tape volume.
You can use an IDCAMS to print the header label and verify that you have UHL (User Header Label) which will confirm you that the tape is encrypted. You will find there BES dataclas used and other BES information into them.
2) Run the MERGE specific to this tape volume
=> it is decrypted
=> a new tape volume is created unencrypted
3) Dump the new tape volume header to verify it is unencrypted. (Use the same IDCAMS to verify this as for step 1)
4) Verify the old encrypted volume is now in the Scratch pool
