Allows you to display details about the replication pair LUNs.
To display the Volume Protection page, choose . The Source Host and Target Host options list the names of the primary and secondary the replication pairs. By default, all of the volume replication pairs display. Use the Plan Name, Source Host, Target Host, and Volume Name filters to narrow the search, and click Search.
Protected volume replication pairs are listed in the
Volume Protection table. Click the plus sign (+) located next to the name of a protection plan to expand the plan details.
Note: If the list is too long, you can filter the search results.
The Volume Protection page displays the following:
- Server
- Names the primary and secondary Replication Engines.
- Volume Agent Pair
- Displays the LUN name and LUID of the source and target LUNs that are included in the protection plan.
Note: The associated Oracle FS System can be determined by the last four digits of the LUID, which would match the last four digits of the serial number of the Oracle FS System.
- RPO
- Displays the recovery point objective (RPO), in units of time.
Note: When the RPO exceeds 120 minutes, the numeric units of the display switches to hours.
- Resync Progress
- Displays the progress of the resynchronization operation in terms of percent complete.
- Status
- Displays the status of the resynchronization operation:
Resyncing (Step I)
Resyncing (Step II)
Differential Sync
- Resync Required
- Indicates whether the target LUNs in the protection plan need to be resynchronized with the source LUNs: YES or NO. Can also show N/A to indicate that the plan is inactive.
- Resync Data in Transit (in MB)
- Displays the number of megabytes of data in transit for Step 1 or Step 2 of a resynchronization.
- Differential Data in Transit (in MB)
- Displays the number of megabytes of data in transit on a Replication Engine process service or on a secondary server.
Note: If the data that is in transit exceeds the value set in the Differential File Threshold option, then replication stops. The replication stops while the data transitions from data mode, which includes write order fidelity, into meta data mode, which is not write order fidelity. When the replication stops, it is an indication of the importance of the Differential Data in Transit option.
- Action
- Displays the protection plan and volume details when Summary is clicked.
The Volume Summary page provides the following
Pair Settings information:
- Primary Volume Size (MB)
- Displays the primary server LUN capacity in megabytes.
- Process Service
- Identifies the name and IP address of the Replication Engine that is running the process service for this volume.
- Secure data transfer Replication Engine Process Service to Secondary Server
- Indicates whether encryption is enabled from the process service Replication Engine to the secondary server.
- Resync Mode
- Indicates the type of resynchronization used for this replication pair.
Resync I
Resync II
Differential Sync
- Target Volume Visible
- Indicates whether the secondary volume on the secondary server is in read‑only mode.
- RPO Threshold
- Sends alerts if the recovery point objective (RPO) exceeds the selected threshold as defined during protection plan creation. The system sends alerts to the designated user and to the Alerts and Notifications section in the Oracle MaxRep GUI.
- Replication Pool
- Identifies the number of the replication pool, possibly one of many, to which this replication pair belongs.
- Resync File Threshold (MB)
- Indicates the maximum storage capacity on the process service Replication Engine to use for storing files during resynchronization, in MB.
- Differential File Threshold (MB)
- Indicates the maximum storage capacity to use for storing files during the differential synchronization, in MB.
- Compression
- Indicates whether to compress the protected data. Yes indicates whether compression takes place at the process service Replication Engine or at the primary server.
- CDP Retention
- Indicates whether continuous data protection (CDP) retention is configured for this replication pair.
- Retention Window Size
- Indicates the period of time that data is retained at the target location as defined during the creation of the protection plan.
The Volume Summary page provides the following
Resync Details:
- Resync Start Time (Step 1)
- Indicates when the initial resynchronization starts.
- Resync End Time (Step 1)
- Indicates when the initial resynchronization ends.
- Resync Start Time (Step 2)
- Indicates when the resynchronization Step 2 starts.
- Resync End Time (Step 2)
- Indicates when the resynchronization Step 2 ends.
The Volume Summary page provides the following
Differential Sync Details:
- Start Time
- Indicates when the differential synchronization starts.
- Last Update Time
- Displays the last updated time from the Replication Engine.
- Agent Log
- Displays as enabled if logs are present.
