P.P.S. NetApp Engineering is looking into building checks for illegal configurations into future versions of ONTAP.
What version are you running? 5.3.4 (and possibly earlier 5.3's) have a "sysconfig -c" which does the check for you. I think it also complains on bootup if it finds unsupported slot configurations. The data is stored in /etc/sysconfigtab on the filer. I noticed that there are already entries for the F840 and C840 filers in there. ;-)
Cluster caveat: If you install a ServerNet cluster interface and a second FC-AL adapter connected to the partner's disks *without* enabling clustering, "sysconfig -c" will report that those two cards are in an unsupported configuration. What it really means is that clustering hardware is not supported until clustering is turned on (well, okay....). Netapp tech support even reproduced the "bug" in their lab, until they realized what was going on. ;-)
