Viewing Redundancy Information

Three commands allow you to view key information about the redundancy feature:

• redundancy show configuration
• redundancy show statistics
• redundancy show status.

Viewing Redundancy Configuration

Enter the following command to view details of the redundancy configuration:
redundancy show configuration

The output will be similar to the following:

Note the following points about the redundancy configuration:

• Replication type: Currently, this is always set to Geo redundant. Other modes may be available in future releases.
• Auto-failover: Possible values are: Enabled and Disabled. It is set to Enabled by default. The system will switch from the active to the passive when it determines that this is necessary. Auto-failover can be disabled, but this should be done with caution. For more information, see Disabling Automatic Failover.

Viewing Redundancy Status

Enter the following command to view the status of the redundancy feature:
redundancy show status

The output will be similar to the following:

The possible redundancy status results are as follows:

• Global Status: Possible values: Started, Stopped, Suspended.
• Node Status: Possible values: Active, Passive, Offline
• Replication status: Possible values: Up, Down, Synchronizing:
• Up means data is being transferred from the active to the passive site.
• Down means data is not being transferred from the active to the passive site. This is normal if the Global Status is Stopped or Suspended. This is not normal if the Global Status is Started.
• Synchronizing means the system is catching up on replicating data. This happens after redundancy starts or after a long suspension.

Viewing Redundancy Statistics

Enter the following command to view statistics about redundancy:
redundancy show statistics

The output will be similar to the following:


Note that the redundancy statistics that displayed are expressed in terms of the site on which you are logged on and currently viewing the statistics:

• Network sent: Data sent from the local site to the other site.
• Network received: Data received by the other site.
• Disk write: Data written on the local site.
• Disk read: Disk read on the local site.
• Out of sync: This value should be close to 0 during normal operations.
