A host is connected to two PowerMax arrays with SRDF/Metro. Host I/Os cannot be delivered across the SRDF link. The devices in the SRDF group have been forced into a Not Ready state to the host. Which attribute is set on the SRDF group to cause this behavior?
When SRDF devices are forced into a Not Ready state because host I/Os cannot be delivered across the SRDF link, it is due to the 'Local Link Domino' attribute. This setting ensures that the devices in the SRDF group are made unavailable if there is an issue with the link, preventing potential data inconsistency or corruption.
