Description
This command enables auto mirror unisolation.
Mirror isolation provides a mechanism to automatically unisolate mirrors that were previously isolated. When mirror isolation is enabled, auto-unisolation allows the system to automatically unisolate the underlying storage-volumes once their performance is in the acceptable range.
Examples
Shows auto-unisolation enabled when mirror isolation is disabled on both clusters:
VPlexcli:/> device mirror-isolation auto-unisolation enable
Mirror isolation is not enabled on clusters cluster-1,cluster-2.
Auto-unisolation is enabled on clusters cluster-1,cluster-2.
Shows auto-unisolation enabled when mirror isolation is disabled on one of the clusters:
VPlexcli:/> device mirror-isolation auto-unisolation enable
Mirror isolation is not enabled on cluster cluster-2.
Auto-unisolation is enabled on clusters cluster-1,cluster-2.
Shows auto-unisolation when mirror isolation is enabled:
VPlexcli:/> device mirror-isolation auto-unisolation enable
Auto-unisolation is enabled on clusters cluster-1,cluster-2.
Shows auto-unisolation enable operation failed as the feature is not supported:
VPlexcli:/> device mirror-isolation auto-unisolation enable
Mirror isolation is not enabled on clusters cluster-1,cluster-2.
device mirror-isolation auto-unisolation enable: Evaluation of <<device mirror-isolation auto-unisolation enable>> failed.
cause: Could not enable auto unisolation.
cause: Could not enable auto unisolation.
Modifying auto unisolation is not supported by this version of firmware.
Shows auto-unisolation enable operation failed because one cluster is not available:
VPlexcli:/> device mirror-isolation auto-unisolation enable
device mirror-isolation auto-unisolation enable: Evaluation of <<device mirror-isolation auto-unisolation enable>> failed.
cause: Could not enable auto unisolation.
cause: Firmware command error.
cause: communication error recently.
Shows auto-unisolation enable operation failed because the meta volume is not ready:
VPlexcli:/> device mirror-isolation auto-unisolation enable
device mirror-isolation auto-unisolation enable: Evaluation of <<device mirror-isolation auto-unisolation enable>> failed.
cause: Could not enable auto unisolation.
cause: Could not enable auto unisolation.
Firmware command error. The active metadata device is not healthy enough to persist the change fully.
