I noticed that the dd time had been reduced from 6m+ to 2m+ when the 'eh_deadline' was set as 30s, but the dd time was 6m+(nearly the same as default - 'eh_deadline' was 0) when the 'eh_deadline' was set as 10s. I havn't been able to dig further, but I guess there is some restriction when setting this 'eh_deadline' interface. Maybe should not less than some timeout, otherwise 'eh_deadline' setting will not work?
I've retried and confirmed that the exception above is caused by misoperation - for I had two fc hosts to build a failover multipath, but I just set 'eh_deadline' on one host. When I tested with 10s, the 'eh_deadline' on the host of the active path wasn't set :-( Sorry for my mistake.
