On excessive bit errors for the FCP channel ingress fibre path, the channel notifies us. Previously, we only emitted a kernel message and a trace record. Since performance can become suboptimal with I/O timeouts due to bit errors, we now stop using an FCP device by default on channel notification so multipath on top can timely failover to other paths. A new module parameter zfcp.ber_stop can be used to get zfcp old behavior.
Ugh, module parameters? This isn't the 1990's anymore :(
Why not just make this a dynamic sysfs variable, that way you properly can set this on whatever device you want, not just "all or nothing"?
thanks,
