Hi,
I have an question on scsi alua handler and VxDMP on Linux.
we have a scsi_dh_alua handler on linux, which can handle the ALUA related check conditions sent from target controllers. so this will be handled by scsi layer itself and will not be propogated to the upper layers.
So do we have anything simalar with VxDMP to handle the ALUA related errors reported by scsi layer or does it depend on scsi_dh_alua handler to handle the ALUA related check condions from target and retry at the scsi layer it self ???
Thanks,
Inbaraj.

I am not very sure on this but I would expect VxDMP to handle this with ASL/APMs. With ASL/APMs in place, DMP module should communicate to SCSI layer (not sure of exact function/handler name) to handle/respond to the errors.
