An environment setup operation is required to convert a Metro session and a DR session into a Smart DR environment which enables the ability to closely couple the SRDF/A sessions from each side of the Metro session when the DR site devices are in SRDF/A asynchronous mode. To set up a Smart DR environment, the user must use the new symmdr environment –setup command in Solutions Enabler 9.2 or similar Unisphere 9.2 interface steps as covered in greater detail within the associated Smart DR Unisphere Setup appendix below.
To perform a Smart DR setup operation, the user will need the following:
Note: The setup operation will not change the state of the Metro or DR session. For example, if the SRDF pair state of the Metro session is ActiveActive and the SRDF mode of the DR session is Asynchronous and the SRDF pair state of the DR session is Consistent. Device states of these SRDF pairs should remain the same after the setup operation has completed.
In addition, the setup operation will adjust the newly created SRDF mirror from the MetroR2 array to the DR array so that it mimics the state of the existing DR states. For example, ensures that the minimum cycle time that exists on the MetroR1 to DR is the same minimum cycle time that exists on the Metro R2 to DR.
SYMCLI setup command example:
symmdr –sid -56 –name metrodr1 –metro_rdfg 119 –dr_rdfg 76 env –setup
A MetroDR 'Environment Setup' operation is in progress for ‘metrodr1’. Please wait...
