Viewing Mirror Status
List mirror volumes and their status using the Control System and the CLI.
You can see a list of all mirror volumes and their current status in the Mirror
Volumes view (in the Control System, select Mirror Volumes from
the drop-down menu in the Volumes page under ) or using the
volume list
command.
Use the volume mirror status command to view the details of the
mirroring operation that is in progress. The volume mirror status
command helps in troubleshooting the mirroring operation. For more information on
trouble shooting mirroring, see the support article titled Monitor and Understand Volume Mirroring in HPE Ezmeral Data Fabric.NOTE
The Volumes page is
under the Volumes menu in the Kubernetes version of the
Control System.To use the volume list command to explicitly list mirror volumes, you must define a filter.
For example:
maprcli volume list -filter [n==<mirror name>] -columns \
n,p,mirror-percent-complete,mrt -cluster <target cluster>
Mirrors and Performance
Completion time for a mirroring operation is affected by the available network bandwidth, and the amount of data to transmit. For best performance, set the mirroring schedule according to the anticipated rate of data changes, and the available bandwidth for mirroring.
