Error Message

VCS ERROR V-16-20017-3 SRDF: :online:devices in group are in an invalid mix of writable states; administrative intervention required

Cause

SRDF replication mode is set to a unsupported mode - only "Synchronous" and "Asynchronous" are supported.

This error may occur if the customer is using the unsupported replication mode of "Adaptive Copy"

 

ex.

# symdg show test-dg
...
RDF Mode : Adaptive Copy
RDF Adaptive Copy : Enabled: Disk Mode
RDF Adaptive Copy Write Pending State : N/A
RDF Adaptive Copy Skew (Tracks) : 32767
...

Resolution

Customer must use symrdf commands to set supported replication mode:

# symrdf -g dgname set mode sync

or

# symrdf -g dgname set mode async
