To setup authorized keys for a Netapp, put the keys in:
/<netapp>/root/etc/sshd/<user>/.ssh/authorized_keys
where <netapp> is just the name of the netapp, <user> is the name of the user account on the netapp. I suggest you make a seperate restricted account for stuff like this.
You can use the 'useradmin role ...' commands to create a user account and then limit which command(s) can be run. Very nice.
