I am getting similar issue with SMO configuring for RAC database having ASM with iscsi luns from netapp.
snapdrive storage show -devices -- finally working after tweaking snapdrive.conf file.
But when i try to register profile getting same error
SMO-13527: Error performing fast restore check: FLOW-11019: Failure in Discover: SD-00018: Error discovering storage for /dev: SD-10016: Error executing snapdrive command "/usr/sbin/snapdrive storage show -fs /dev -v": 0001-185 Command error: storage show failed: no NETAPP devices to show or add the host to the trusted hosts (options trusted.hosts) and enable SSL on the storage system or retry after changing snapdrive.conf to use http for storage system communication and restarting snapdrive daemon.
/dev -- not found, additional information not available
..
Please help with the steps needed for ASM storage configuring using smo.
Thanks,
Srini
