Member CTETEVLT of the CA 1 or CA TLMS EARL data set hlq.CTAPEARL is provided for users who also run the CA Tape Encryption product. Use CTETEVLT to identify if tapes being sent off-site are protected with encryption.
CA Tape Encryption creates a BES Key Index for each new symmetric key instance. The BES Key Index is saved in the CA 1, CA TLMS, or IBM DFSMSrmm tape catalog record for each encrypted file. EARL field BES_KEY, in the common record, reports on the BES Key Index. If the BES_KEY field is not zero, the file is encrypted. This lets you quickly identify an encrypted tape by comparing the BES_KEY field to zero.
Report CTETEVLT checks the BES_KEY for each file in the tape catalog that is selected for movement off-site "today". A BES_KEY of zero, causes the report to end with an RC=8 to alert you that not all tapes are protected.
Report CTETEVLT uses CTSEPM pattern masking capability to either include or exclude data sets matching specific name patterns. The pattern matching techniques that are used in the CTETEVLT EARL report provide a good example for exploiting this feature in user written EARL reports.
