Checking Source and Target Compatibility

Remote replication is compatible between most Oracle ZFS Storage Appliance software versions. Compatibility failures are caused if a replication update uses a feature that is not supported on the replication target. Features are delivered with software updates or as deferred updates.

For details about compatibility and deferred update features for each software version, see the Oracle ZFS Storage Appliance Remote Replication Compatibility document (Doc ID 1958039.1) on My Oracle Support (http://support.oracle.com/).

  1. Check the current software version on the source and target appliances.
    • BUI - From the Maintenance menu, select System.
    • CLI - Navigate to maintenance system updates and enter show.
  2. Ensure that the replication target provides support for any deferred update feature used by the source project or share.

    For example, if the source share uses large blocks, ensure that the replication target provides support for this feature. As another example, if the source share uses the mandatory file retention policy, the replication target pool must have a redundant profile and, therefore, the striped profile cannot be used.

  3. Update software and apply deferred updates on the replication target, as needed.

    For more information, see Deferred Updates in Oracle ZFS Storage Appliance Customer Service Manual, Release OS8.8.x.

  4. If the project or share to be replicated is encrypted, ensure that the encryption key used at the source is also available at the target.

    For information about configuring encryption keys, see Data Encryption.

  5. Optional: On the source and target appliances, set the SSL/TLS versions and ciphers for replication as described in Configuring SSL/TLS Versions and Ciphers.

    Set the values according to your site's security requirements. The versions and at least one of the ciphers must be identical on the source and target appliances. Oracle ZFS Storage Appliance systems running older firmware might not support ciphers offered in newer TLS versions.
