Hi,

I'm having a problem with nmonversion 10 and 11 on one of my server.
It's not collecting or displaying the stats correctly on the HBAs but
curriously version 9a does it OK.

It repeats fcs1 5 times in the display of version 11 and 10 of nmon:
nmon m=Memory Host=sxpjde0001 Refresh=2 secs 11:51.11

It's also reflected in the nmon2rrd collection:

The server is running AIX 5.2 ML02 and it's connected to a Hitachi HDS.

We have serveral AIX 5.2 servers connected to the HDS but this is the
only one showing this problem. The only thing different is that this is
the only one using 4 HBAs.

Thanks in advance
