You can use the command-line interface (CLI) to reverse
the roles of primary and secondary virtual disks in a stand-alone Metro
Mirror or Global Mirror relationship
when that relationship is in a consistent state. Relationships that
are members of consistency groups must be switched by using the consistency
group CLI commands.
To switch the roles of primary and secondary VDisks in Metro
Mirror or Global Mirror relationships,
follow these steps:
- To make the master disk in a Metro
Mirror or Global Mirror relationship
to be the primary, run the svctask switchrcrelationship
-primary master command. For example,
enter:
svctask switchrcrelationship -primary master rc_rel_id
Where rc_rel_id is the ID of the
relationship to switch.
- To make the auxiliary disk in a Metro
Mirror or Global Mirror relationship
to be the primary, run the svctask switchrcrelationship
-primary aux command. For example, enter:
svctask switchrcrelationship -primary aux rc_rel_id
Where rc_rel_id is the ID of the
relationship to switch.
