Wow. Lots of really good advice from several folks. I have it working on the command line as well, so that makes some things easier. It seems that if I have one or two option areas that I care about, having a specific script to examine might be better than asking DFM to generate a full comparison report (which will have lots of differences that I might not care about).
Got all the plugins. Almost all the data received. Now I just have to figure out why a few filers that otherwise report fine in Ops manager don't get the detailed information for the configurations.
$ dfm config dump <filer> Error: Failed to pull configuration from <filer>(3972). Unable to open /vol/vol0/etc/dfm-10.0.36.39-04082011084439.cfg: No such file or directory Error: Failed to get configuration dump from <filer>.
Thanks again for all the pointers

Operations Manager (DFM) offers the ability to compare the configurations of all the systems, and report on any differences.
Download DFM plugins for all relevant versions of Data ONTAP.
In the DFM GUI, go to Management > Storage System > Configuration
Files
- Create a new configuration file and call it something similar to
baseline.options.config.
- In DFM GUI, go to Management > Storage System > Compare
Configurations
- Compare the baseline.options.config to the other filers that should
have the same configuration information.
- Refresh and click on the completed job to view any differences

I would like to check the options on my filers for various items, but I'm not sure the best way to do it. Could anyone tell me if I'm missing something?
SNMP and Operations Manager: I don't see that I can pull the data from either of these sources.
SSH and SDK access: I could create an account, but it seems to me that the only restriction available is the ability to run the "options" command. There's no way to grant an account read-only access to the data. I'd rather not give the monitor direct access to modify things.
NFS: The current options appear to be visible as a local file in /etc, but creating NFS access to vol0 for lots of filers for a single file seems more of a hassle to me.
At the moment I'm leaning toward a collector that would poll all the filers via SSH or SDK to run "options" and dump that into static files on a normal export that the monitoring system could examine. Anyone have any other suggestions?
Thanks!

Hello Toasters,
I am in the process of moving our data to new shelfs via snapmirror. In my last test I swichted to the new vols, rebooted and realized that our iSCSI settings (initiator groups, mappings) where missing.
Where are they stored? Is there something I forgot? Is there any Document I should read?
Thanks from Hamburg,
René

When you snapmirror a volume that contains LUNs, you create new LUNs and the old LUNs are still present.
I've always run this:
lun show -v
to see the old LUN mappings, offlined the old LUNs and mapped the new LUNs, etc.
lun map ...
If you are moving to a new filer, you can run
igroup show
on the old filer and create the igroups on the new filer.
igroup create ...
If moving to a new filer, you need to migrate the iscsi login accounts. So on the old filer run
iscsi security show
to get your iscsi login accounts. Unfortunately, this doesn't show you the passwords (don't know how to get them) but you can often get them from the iscsi initiator systems, or else just add the accounts on the new filer with new passwords and change them on the initiators.
iscsi security add ...
