I had the issue
Cannot process consistency group 'test' with role 'target' when expected consistency group role 'promotedTarget'
Which happened after I ran SRM in disaster recovery mode.
I had the storage guy set the luns correctly to RW in DR and to RO in the original protected site. Then he re-enabled the replication from DR to Pro
Then it didnt work straight away but when I came back the next day and tried it again it did.
