Basic Commandsbackendbus -get -all (CX3 series and CX4 series only)Displays the bus speeds, SFP state, and physical location of thebus.DescriptionThe naviseccli backendbus command with the -get -all functiondisplays the bus speeds and the current condition of each back-endSFP, which is a small form-factor pluggable (SFP) optical modulartransceiver for the back-end buses on a storage system. It displays thephysical location of the back-end bus (I/O module and the physicalport ID) only for the CX4 series storage system.You can target aspecific back-end bus and display information for only that bus, oryou can display back-end bus information for all buses on the storagesystem.The current speed indicates the speed the bus is currently running at;the available speed(s) indicates the speed(s) available to the back-endbus. If the current speed is less than the maximum available speed,you can run the backendbus -analyze command to verify if there arelimiting devices on the back-end bus. If a device is limiting, it has amaximum speed lower than the maximum speed of the back-endbus. If you have a limiting device, a reset will not occur when youissue backendbus -resetspeed.The SFP states are Online, Faulted, and Removed. Online indicatesthat the back-end SFP is functioning normally; Faulted indicates anunsupported or faulted SFP; and Removed indicates that it does notexist.Use backendbus -analyze to display speed information for eachdevice on a back-end bus.Syntax backendbus -get -all is used with naviseccli (described on page 37)as follows.backendbus -get -all [backend bus number]PrerequisitesOptionsYou must have a user account on the storage system on which youwant to execute the command.backend bus numberSpecifies the back-end bus for which you want to display businformation.74 EMC Navisphere Command Line Interface (CLI) Reference
