However after the SnapDrive wizard completed the below error appears:
Restarting the snapdrive daemon...
Successfully stopped daemon
WARNING!!! Unable to find a SAN storage stack. Please verify that the appropriate transport protocol, volume manager, file system and multipathing type are installed and configured in the system. If NFS is being used, this warning message can be ignored.
Successfully started daemon
I can't find any documentation or support documents that are able to resolve this error?
The Windows SnapDrive is much more straight-forward and just works as required. So any help would be great guys! Thanks.
How is this particular OpenSUSE VM going to be connecting to the target NetApp array? If this is just a VM that will not connect to any outside storage you shouldn't need to install SnapDrive nor the host utilities. If you do plan for the VM to connect to external storage please reply with the protocol that you plan on using. In the chance that you are planning on connecting this VM to external storage via NFS then you can safely ignore this error message.
Checkout this document which explains the entire iSCSI setup process for Linux-based systems (including dm-multipath setup). Once dm-multipath is setup and configured the "Unable to find a SAN storage stack" error message should go away.
We are already using the iSCSI target to a NetGear appliance, however this device does have any redundancy. So I need to move the iSCSI target to our NetApp filers.
iSCSI is already setup and working, I'm use to normally having a GUI for setting up SnapManager and the Linux documentation for this doesn't provide either enough information or clear resolutions. I've created a volume on a filer using OnCommand, no LUN has been created at this point.
Looking through the installation documentation for SnapDrive for UNIX 'sdconfcheck' gives some feedback:
localhost:/etc/iscsi # sdconfcheck version
SnapDrive Configuration Checker Version 1.2.0
localhost:/etc/iscsi # sdconfcheck detect
NOTE: SnapDrive Configuration Checker is using the data file version v12052013
Please make sure that you are using the latest version. Refer to the SnapDrive for Unix Installation and Administration Guide for more details.

I've followed all the documentation up to this point, so I am unsure why I am having issues in the items in bold above?
If I understand correctly you have configured the iSCIS initiator service however you have not yet setup multipathing correct? If that is correct you need need to configure dm-multipath by populating "/etc/multipath.conf" with the necessary content (see the link I posted earlier). Once that is done the error message should go away. Even after the error message goes away you might want to create a test LUN & igroup and see if you see it from the host side (just to make sure everything is configured properly).
