I noticed something very peculiar with regards to the interactive output from nmon on the [b]fcs0,fcs1[/b] adapter stats. For some reason even though the HBA cards are doing balanced I/O (separate attachment from switch stats), [b]fcs1[/b] seems to be display the cumulative I/O and [b]fcs0[/b] with none of the I/O. I don't recall seeing this in versions previous to 10 (it's happening in [b]10r[/b] as well as [b]11d[/b]).
We are running AIX 5.3 ML3 (64 bit) as well as the same model of HBA's. Please let me know if you need any more information regarding our configuration and/or whether anyone can confirm this.
