Data Error Identification Prior to Role Reversal on a Remote Data Replication Facility - A simplified explanation of the abstract
This abstract first appeared for US patent application 18064318 titled 'Data Error Identification Prior to Role Reversal on a Remote Data Replication Facility
Simplified Explanation
Before switching roles on a remote data replication system, a data verification process is used to find any errors in the data. This helps prevent issues during failover or failback procedures. The process involves comparing data on the primary storage array with data on the backup storage array to ensure they match.
- Data verification process implemented before role reversal on remote data replication facility
- Full data scan compares Data Integrity Field (DIF) information on primary and backup storage arrays
- Quick scan compares metadata signatures on primary and backup storage arrays
- Errors identified in backup data can be corrected before role reversal

Questions about Data Verification Process for Remote Data Replication Systems
How does the data verification process ensure data integrity during role reversal?
The data verification process compares Data Integrity Field (DIF) information and metadata signatures between the primary and backup storage arrays to identify any errors before switching roles.
What are the potential implications of data mismatch errors during failover or failback procedures?
Data mismatch errors can lead to data loss, corruption, and system downtime, highlighting the importance of the data verification process in preventing such issues.
Original Abstract Submitted
A data verification process is implemented before performing role reversal on a remote data replication facility to identify data mismatch errors prior to failover or failback on the remote data replication facility. In situations where the role reversal is planned sufficiently far in advance, a full data scan is implemented by comparing the Data Integrity Field (DIF) information of each track of data on the primary storage array with the DIF information of each corresponding track of data on the backup storage array. In situations where the role reversal is more imminent, a quick scan is implemented by comparing metadata signatures for each track of data on the primary storage array with the metadata signatures of each corresponding track of data on the backup storage array. Once any data mismatch errors are identified, the data on the backup storage array can be corrected prior to role reversal.
