Device SA Status
Hi,
I'd like to know the correlation between the Device Status and Device SA Status when we have a device in Suspend RDF state and another device in Synchronized RDF state.
What does the SA Status represent in a Fibre Channel environment?

It would be helpful if you could provide a text/screen capture of the outputs you're referring to here.. but here are my thoughts:
Device SA Status refers to the status of a device on a specific front end port. For example, you have the ability to set a device as Not_Ready on one FA port, and leave it in a RW_Enabled state on another FA port.
The Device Status you're referring to is most likely either the overall status of the logical volume (eg NR, RW_Enable, RO), or the SRDF status of the device (eg Split, Consistent, FailedOver, Partitioned, etc).
Thanks,

However, I saw on another meta device on the same frame that is also in a Synch'd RDF state with Device Status of Write Disabled and Devices SA Status of Ready.
Each device is only across the standard 2 FAs and should add that they are on different front-end adapters.. Not really understanding the difference here. You also mentioned the ability to chnage the status of Device SA?
Thanks
