The remote replication pair for which you want to initiate a primary/secondary
switchover is not added to a consistency group.
Primary/Secondary switchover can be performed when synchronous remote replication
is in the following states:
– Pair Running Status is Normal, Secondary Resource Data Status is
Synchronized, and Status of Secondary Resource Protection is Read-only.
– Pair Running Status is Split, Secondary Resource Data Status is Consistent,
and Status of Secondary Resource Protection is Read/Write.
Primary/Secondary switchover can be performed when asynchronous remote replication
is in the following states: Pair Running Status is Split, Secondary Resource Data
Status is Consistent, and Status of Secondary Resource Protection is Read/Write.
