Changing a mirroring schedule for local peers

Use the mirror_change_schedule command to change the replication schedule for peers on the local system.

mirror_change_schedule < vol=VolName | cg=cgName > [ target=TargetName ] schedule=Schedule

Parameters

Name Type Description Mandatory Default
vol Object name Volume name on the local system. N N/A
cg Object name CG name on the local system. N N/A
target Object name Target name of the mirror, mandatory if there are two mirrors defined on the volume. N [none]
schedule Object name A reference to a mirroring schedule. Y N/A

This command changes the replication schedule for a peer on the local system. The new scheduling will become effective only if the peer is set as master.

Prerequisites:
  • The coupling must be ASYNC_INTERVAL.
  • The schedule’s interval has to be shorter than the corresponding mirror's RPO.
The command fails under the following conditions:
  • The specified target does not exist
  • The specified target is non-mirrored
  • The specified target is a volume that belongs to a mirrored consistency group
  • The specified target synchronization type is not ASYNC_INTERVAL
Setting a scheduling reference:
  • The system displays the following warning: ″Are you sure to change schedule″
  • An event is generated
  • New sync jobs will be generated according to updated schedule. A running sync job is unaffected.
