Monitoring and maintaining the TC system

Parent Topic

• TrueCopy

  TrueCopy synchronous remote replication software duplicates data from one storage system to another at a remote location. TrueCopy automates the recovery process and enables normal business operations to resume in minutes rather than hours or days following an outage at the primary site. TrueCopy software provides host-independent data replication, including heterogeneous replication capabilities for any type of data across long distances, without affecting application performance. Copies generated by replication software products can be used for the rapid recovery of production systems or the restart of production on disaster recovery systems following an outage. They can also be used for data warehousing, data mining, or data migration applications.

Child Topics

• Monitoring pair status and license capacity

  You should monitor the TrueCopy system frequently to keep track of and maintain the copy pairs.

• Monitoring TC pair synchronization rate

  You can check on the percentage of synchronized data between the P-VOL and S-VOL.

• Monitoring TC operations history

  In HDvM - SN, you can review the history of operations for a pair, including the operation's description, date and time it took place, primary and secondary system information, and other details.

• Changing P-VOL fence level
• Forcibly deleting pairs

  You forcibly delete a pair using HDvM - SN for the following reasons: A currently unpaired volume that was previously in a pair is unusable because previous pair information is still in the volume, or the pair cannot be connected to the remote storage system because of a communication error.

• Saving pair information to a text file
• Monitoring copy operations and I/O statistical data

  In HDvM - SN, you can monitor copy operations and I/O statistical data.

• Monitoring and maintaining remote connections and paths

  You can access information about remote connections and paths to determine their status. This information is useful when you are diagnosing connectivity between the primary and secondary systems.

• Deleting remote connections

  You can delete the remote connection from the local storage system to a remote storage system.

• Managing power-off for systems and network devices

  You might have to have a planned outage of the primary system, the secondary system, or both to maintain the systems.
