What is the proper way to change iSCSI and NFS IP used to access the storage domains?  My IB fabric which was doing storage crashed and we have a scheduled maintenance window for next week at which time I'd like to either move my storage to 10GbE or back to IB.  I was able to move things off IB to standard TCP/IP by editing the database but that is likely not the correct way.  I am on ovirt 3.4.3.  My NFS domain is the master and iSCSI data domain is only used by two VMs while NFS is used by ~30 VMs.
