Primary takeover

The Primary role can be arbitrarily taken over by a Secondary node. This process is similar to a Primary role migration but presumes that the old Primary is inoperable and unable to participate in the migration process.

Primary takeover is intended to support disaster recovery applications. Only a limited number of error scenarios prior to loss of the Primary node can prevent a takeover because they leave the RLINK in an inconsistent state. All such scenarios require the hardware failure of a data volume or SRL.
