Field Description
from-cluster
Cluster ID of the source device, or devices in the consistency group.
percentage-done
Percentage completion of the migration. 100 % if migration is complete or committed.
source
Source device.
source-exported
Whether the source device was exported during the migration. Applicable if the migration
is an inter-cluster device migration and if the device was not already exported. Devices
are exported to a remote cluster to make them visible at that cluster and can be used as
a leg in a temporary distributed RAID 1 during the migration.
● false - Source device was not exported.
● true - Source device was exported.
start-time
Date and time migration was started.
status
Status of the migration.
● ready-The migration is ready.
● queued-The migration is in the queue.
● in-progress-The migration is in progress.
● paused-The migration is paused.
● Commit Pending-The migration is complete (but not committed).
● committed-The migration is committed.
● Partially-committed-The commit operation is failed.
● error-Error condition, including source or target unreachable.
● cancelled-The migration is cancelled.
● partially-cancelled - Attempt to cancel the migration failed. Retry the cancel.
target
Destination device.
target-exported
Whether the target device was exported during the migration.
● false - Target device was not exported.
● true - Target device was exported.
to-cluster
Cluster ID of the destination device.
transfer-size
Size of the region in cache that is used to service the migration. 40 KB-128 MB.
type
Type of rebuild.
● full - Copies the entire contents of the source to the target.
● logging - Copies only changed blocks from the source to the target.
