Continuous Access replication Tunnels

Ivan Ferreira — Thu, 09 Nov 2006 16:31:00 GMT

I can't find information about how the replications tunnels are created for a EVA CA replication.

I want to know, in a two fabric redundant SAN, if one of the fabrics goes down, how it will affect to the replication? Will the Controller Software use an alternate path or dr tunnel? Will detect the failure and create a new drt?

The information you are looking for is in USC423S B.0 HP Replication Student Guide, module 11. Only covers HSV110 controllers.

Each source controller can have a maximum of two tunnels to a specfic array (one tunnel to ctrl A and one to ctrl B)

Tunnels are created and opened based on information received from the FC fabric (RNID) if a DR group exist. This information is pulled from the switch the EVA is connected to every 10 seconds. Tunnels are closed when the link between the source and dist. ctrl goes down or when the DR groups between the source and dist. are deleted.
