To find out a little more of what this feature does, have a read here: http://www.opensolaris.org/jive/thread.jspa?threadID=12523&tstart=0 > > Is it possible to monitor *somehow* whether the variable becomes > sort of bottleneck ?

What you are doing when you set these commands is effectivly limiting the total number of io requests to a particular device. This is "recommended" with arrays because they share out multiple "luns" over a single port and thus the number of io requests from the hosts may overwhelm the FEP. > Regards > przemol _______________________________________________ dtrace-discuss mailing list [email protected]
