With the LPAR tool, statistics for all virtual FC clients can be displayed at any time using the “vios fcstat” command. This allows you to determine at any time which client LPARs have which I/O throughput (when using NPIV).
Which NPIV-capable FC adapters are available on a virtual I/O server can easily be found out with “vios lsnports“:
$ vios lsnports ms15-vio1 NAME PHYSLOC FABRIC TPORTS APORTS SWWPNS AWWPNS fcs0 U78CB.001.XXXXXXX-P1-C5-T1 1 64 62 2032 2012 fcs1 U78CB.001.XXXXXXX-P1-C5-T2 1 64 62 2032 2012 fcs2 U78CB.001.XXXXXXX-P1-C5-T3 1 64 61 2032 1979 fcs3 U78CB.001.XXXXXXX-P1-C5-T4 1 64 61 2032 1979 fcs4 U78CB.001.XXXXXXX-P1-C3-T1 1 64 50 3088 3000 fcs5 U78CB.001.XXXXXXX-P1-C3-T2 1 64 63 3088 3077 $
We display the FC client statistics with the command “vios fcstat”. By default, the data for all virtual FC clients of the specified virtual I/O server are shown every 10 seconds:

The LPAR name, the physical FC port (PHYSDEV) on the virtual I/O server, the WWPN of the client adapter, the virtual FC client port (DEV), as well as the number of requests (INREQS and OUTREQS) and thereby transferred bytes (INBYTES and OUTBYTES). The transfer rates are output in KB/s, MB/s or GB/s. The output can be very long on larger systems! The output is sorted according to throughput, i.e. the most active virtual client adapters are output first. With the option ‘-t‘ (top) the output can be restricted to a desired number of data records: e.g. with ‘-t 10‘ only the top ten adapters with the highest throughput are shown. In addition, the interval length (in seconds) can be specified via a further argument, here is a short example:

With the “vios fcstat” command, FC throughput of any LPAR can be shown at any time in an extremely simple way, at the push of a button, so to speak.
If the intervals are smaller, the accuracy of the displayed values suffers. At 2 second intervals the inaccuracy is approx. 10%. However, the relationship between the displayed values is still correct.
