Create a plan that includes all of the environments where CA Tape Encryption will run before commencing installation.
Business Value:
Planning ahead to identify the z/OS system and cryptographic components available at your disaster recovery (DR) site ensures that CA Tape Encryption can initialize and run smoothly at DR. This avoids any problems with not having the required cryptographic components available at DR. For example, if your production site runs a z9 with CPACF enabled and your DR site runs a z890, the CPACF processor may not be enabled at the DR site. This would require you to use slow software-based algorithms rather than the fast hardware-based implementations of the algorithms
Additional Considerations:
If a third party hosts your disaster recovery processing, contact them to identify the cryptographic capabilities of the systems at DR.
