Displaying continuous replication information and status

The Replication> continuous show and Replication> continuous status commands display information on continuous replication which allows you to confirm any changes that are made to your replication file system and view the current file system status.

To display the list of file systems which are configured under continuous replication

  • To display the list of file systems which are configured under continuous replication, enter the following command:
    Replication> continuous show

To display the status of a replication file system

  • To display the status of a replication file system, enter the following command:
    Replication> continuous status fs_name

    fs_name

    Specify the file system name that you have configured for continuous replication.

Table:  describes the important attributes displayed by the Replication> continuous status command.

Table:

Attribute

Description

Replicated Data Set

Specifies the name of the replicated data set

Replication role

Specifies the role of the cluster in continuous replication. It is either primary or secondary.

Replication link

Specifies the link name which is created during the authentication of the source and the destination cluster.

Primary site Info

Provides the details of continuous replication related to the source cluster like host name and RVG state.

Secondary site Info

Provides the details of continuous replication related to the destination cluster like host name, configured mode, data status, replication status, current mode and timestamp information.

Host name

For the primary site, it provides the continuous replication IP which binds on the source cluster using the Replication> continuous config bind command.

For the secondary site, it provides the continuous replication IP which binds on the destination cluster using the Replication> continuous config bind command.

RVG state

Specifies the state of the primary RVG.

See Table: RVG status for details on its various states.

Configured mode

Specifies the continuous replication configured mode. It may be synchronous-override or asynchronous.

Current mode

Specifies the mode of replication - asynchronous or synchronous, that is used to replicate data to the secondary.

Data status

Shows the data status for the secondary.

See Table: Data status for details on its various states.

Replication status

Specifies the status of the replication to the secondary.

See Table: Replication status for details on its various states.

Logging to

Indicates whether updates for the secondary are tracked on the primary using the SRL or DCM.

See Table: Logging to status for details on its various states.

Timestamp information

Shows the time by which secondary is lagging behind the primary.

Table: RVG status describes the values for the RVG state.

Table: RVG status

Value

Description

acting_secondary

The primary RVG is currently the acting secondary as part of the fast failback process. Writes to the data volumes in this RVG are disabled independent of whether the RVG is started or stopped.

disabled for I/O

Primary RVG is disabled for I/O. The RVG is stopped.

enabled for I/O

Primary RVG is enabled for I/O. The RVG has been started.

needs recovery

State of the RVG after an import or reboot.

Passthru

The primary RVG is in passthru mode because the primary SRL is detached or missing.

Table: Data status describes the values for the Data status.

Table: Data status

Value

Description

consistent, behind

Secondary data is consistent but not up-to-date with the primary data.

consistent, stale

The data on the secondary is consistent. Replication to the secondary has been stopped. The primary RLINK is detached.

consistent, up-to-date

The secondary data is consistent and is current or up-to-date with the primary data. The primary role can be migrated to the secondary.

inconsistent

The data on the secondary volumes is not consistent and the secondary cannot take over.

N/A

Current state of the secondary data cannot be determined. This may occur because of a configuration error on the secondary.

Table: Replication status describes the values for the Replication status.

Table: Replication status

Value

Description

logging to DCM

DCM is active for the secondary. New updates on primary are tracked using DCM for the secondary.

The following information may be displayed:

  • needs dcm resynchronization - Resynchronize the secondary using DCM resynchronization to continue replication.

needs failback synchronization

The primary RVG is acting as secondary as part of the fast failback process. Start failback resynchronization on the new primary to continue replication.

not replicating

Data is not being replicated to secondary because primary RLINK is in needs_recovery state.

  • primary needs_recovery - Primary RLINK needs to be recovered before replication can resume.

paused by user

Replication to secondary is paused due to some administrative action. This results in the following states:

  • primary paused - primary RLINK is paused.

  • secondary paused - secondary RLINK is paused.

paused due to error

Replication to secondary is paused due to the following errors:

  • secondary config error - secondary has some configuration error.

  • secondary log error - secondary SRL has an I/O error.

paused due to network disconnection

Replication to secondary is paused due to some network problem.

replicating

Replication can take place if there are updates on the primary data volumes.

resync in progress

Resynchronization to the secondary is in progress.

  • autosync - Resynchronization type is autosync.

  • dcm resynchronization - resynchronization after an SRL overflow.

  • failback resynchronization- resynchronization using failback logging.

  • smartsync - resynchronization type is autosync using SmartMove.

resync paused by user

Resynchronization to secondary is paused due to some administrative action. This results in the following states:

  • primary paused - primary RLINK is paused.

  • secondary paused - secondary RLINK is paused.

resync paused due to error

Resynchronization to Secondary is paused because of the following errors:

  • secondary config error - secondary has some configuration error.

  • secondary log error - Secondary SRL has an I/O error.

resync paused due to network disconnection

Resynchronization to secondary is paused due to some network problem.

stopped

Replication to secondary is stopped due to the following:

  • Primary detached - Primary RLINK is detached

  • Secondary detached - Secondary RLINK is detached.

N/A

The replication status cannot be determined.

Table: Logging to status describes the values for the Logging to field.

Table: Logging to status

Value

Description

DCM (contains xxx Kbytes) (log_type)

DCM is active (in use) for the replication to the secondary. The log_type can be autosync, failback logging, or SRL protection logging. The yyy% value can sometimes reach beyond 100%. If synchronization is restarted and the DCM map is full, new incoming writes cause the total yyy% to exceed 100%.

SRL (xxx Kbytes behind, yyy % full)

Updates to be transferred to secondary are logged into the SRL and are currently occupying xxx Kbytes or yyy% of the SRL.

SRL

SRL is used for logging. Check the Data status field for the status of the secondary data.
