Is there a way to set those iscsi target tuning values for all targets at once? or something as a default? setting one value takes a while, around a minute. so setting 2 values on 40 targets will take me 80 minutes. And I think i'm going to tune a lot. So i hope you see how that an be a problem...

what do you mean by you concern. That i should use bonding of should'nt use bonding?
