consistency-group choose-winner
Selects a winning cluster during an inter-cluster link failure.
Contexts
All contexts.
In /clusters/cluster-n/consistency-groups/group-name context, command is choose winner.
Syntax
consistency-group choose-winner
[-c|--cluster] cluster
[-g|--consistency-group] consistency-group
[-f|--force]
Arguments
Required arguments
[-c|--cluster] cluster *The cluster on which to roll back and resume I/O.
[-g|--consistency-group]
consistency-group
* Context path of the consistency group on which to roll back and resume I/O.
Optional arguments
[-f|--force]
Do not prompt for confirmation. Allows this command to be run using a non-interactive
script.
* - argument is positional.
Description
Use the choose-winner command when:
● I/O must be resumed on a cluster during a link outage
● The selected cluster has not yet detached its peer
● The detach-rules require manual intervention
The selected cluster will detach its peer cluster and resume I/O.
CAUTION:
When the clusters cannot communicate, it is possible to use this command to select both clusters as
the winning cluster (conflicting detach). In a conflicting detach, both clusters resume I/O independently.
When the inter-cluster link heals in such a situation, manual intervention is required to pick a winning cluster.
The data image of the winning cluster will be used to make the clusters consistent again. Any changes at the
losing cluster during the link outage are discarded.
Do not use this command to specify more than one cluster as the winner.
