  • Page 51: Naming A Connection

    Using the CLI Naming a connection This command is used to name the association between the Fibre Channel Initiator (HBA in the server) and the MSA, while at the same time identifying the operating system (connection profile) of the server. The name given to a connection is user defined, according to a naming convention that makes identification and setup of the ACL for each connection easier.
