Before upgrading to ONTAP 8.1.2 we are trying to update all the firmware. According to the Upgrade Advisor Plan, it says our current Service Processor version is 2.1, and recommends we upgrade to 2.1.1. The NetApp support site gives me to options to do the update, either via the Service Processor Command Line Interface or Data ONTAP Command Line Interface.
I'm not sure which ones which, and whether we need to download it from somewhere. Is it even necessary. So far we've been doing everything via SSH. Is this update somehow different?
One other question that the Upgrade Advisor mentions: "The VLD protocol is licensed on this node and ONTAP 8.1.2 does not support VLDs. If VLDs exist on this system, SnapDrive must be upgraded to at least version 3 and the VLDs must be converted to iSCSI LUNs."
What are VLDs?
Since we only use NFS volumes, does this apply to us or can we ignore it?
