3ware allows for a browser interface to be used, however unless accessed locally this can be a security risk. Therefore we suggest using the command line interface if at all possible.
You need to download the 3ware CLI utilities from the vendor website or from your datacenter portal. Installation is as simple as unzipping the file into a separate folder. Please note you MUST be root/administrator to run the utility.
