There are several SnapMirror active sync components and operations you can monitor. |
You can monitor the following SnapMirror active sync operations to ensure the health of your SnapMirror active sync configuration:
-
ONTAP Mediator
-
Planned failover operations
-
Automatic unplanned failover operations
-
SnapMirror active sync availability
Note
|
Beginning in ONTAP 9.15.1, System Manager displays the status of your SnapMirror active sync relationship from either cluster. You can also monitor the ONTAP Mediator’s status from either cluster in System Manager. |
During normal operations, the ONTAP Mediator state should be connected. If it’s in any other state, this might indicate an error condition. You can review the Event Management System (EMS) messages to determine the error and appropriate corrective actions.
You can monitor status and progress of a planned failover operation using the snapmirror failover show
command. For example:
ClusterB::> snapmirror failover start -destination-path vs1:/cg/dcg1
Once the failover operation is complete, you can monitor the SnapMirror protection status from the new destination cluster. For example:
ClusterA::> snapmirror show
Refer to the EMS reference to learn about event messages and corrective actions.
During an unplanned automatic failover, you can monitor the status of the operation using the snapmirror failover show
command.
ClusterB::> snapmirror failover show -instance Start Time: 9/23/2020 22:03:29 Source Path: vs1:/cg/scg3 Destination Path: vs3:/cg/dcg3 Failover Status: completed Error Reason: End Time: 9/23/2020 22:03:30 Primary Data Cluster: cluster-2 Last Progress Update: - Failover Type: unplanned Error Reason codes: -
Refer to the EMS reference to learn about event messages and about corrective actions.
You can check the availability of the SnapMirror active sync relationship using a series of commands, either on the primary cluster, the secondary cluster, or both.
Commands you use include the snapmirror mediator show
command on both the primary and secondary cluster to check the connection and quorum status, the snapmirror show
command, and the volume show
command. For example:
SMBC_A::*> snapmirror mediator show Mediator Address Peer Cluster Connection Status Quorum Status ---------------- ---------------- ----------------- ------------- 10.236.172.86 SMBC_B connected true SMBC_B::*> snapmirror mediator show Mediator Address Peer Cluster Connection Status Quorum Status ---------------- ---------------- ----------------- ------------- 10.236.172.86 SMBC_A connected true SMBC_B::*> snapmirror show -expand Progress Source Destination Mirror Relationship Total Last Path Type Path State Status Progress Healthy Updated ----------- ---- ------------ ------- -------------- --------- ------- -------- vs0:/cg/cg1 XDP vs1:/cg/cg1_dp Snapmirrored Insync - true - vs0:vol1 XDP vs1:vol1_dp Snapmirrored Insync - true - 2 entries were displayed.
