Navisphere Command Line Interface (CLI) Reference - VMware Communities

Basic Commandsndu -installDescriptionTransfers SP software driver packages to the storage-system privateLUN (PSM LUN)The ndu command with the -install function transfers files frommedia to the storage system, queries and displays information aboutthe packages, and then installs or upgrades selected softwarepackages.Note: For AX series storage systems the process is disruptive.The ndu command is not supported on NetWare and HP-UX operatingsystems. The ndu command is only supported by Secure CLI in NavisphereCLI versions 6.24 and later.The naviseccli ndu command -install function transfers one or moreSP driver packages from a user-accessible file system to thestorage-system private storage LUN (PSM). Media should be presentbefore you issue this command.Note: Beginning with FLARE Operating Environment version02.19.xxx.5.yyy, when you execute ndu -install, the CLI performs a series ofpreinstallation validation checks on a CX3 series, CX series, AX4-5 series, orAX series systems, prior to installing or upgrading customer-installablesoftware packages. Prior to issuing the install, you must satisfy the specifiedconfiguration requirements for the preinstallation validation checksfunctionality, or the installation will not complete. See “Preinstallationvalidation checks” at the end of this section for configuration requirements.You should use a Windows-based Navisphere client (eitherNavisphere Manager or Navisphere CLI) to install software.Before starting a non-disruptive software installation, record the readand write cache sizes because they will be set to zero.Before the SP starts a nondisruptive software installation, it disablesthe caches and sets their sizes to zero. If the write cache is full andI/O is heavy, disabling the cache may take over an hour because thecached data must be written to disk. After the data is written, theinstallation starts.When you install new SP software using the CLI, the only way todetermine when the installation is finished is to issue periodic naviclindu -status commands until the CLI shows the operation iscompleted.224 EMC Navisphere Command Line Interface (CLI) Reference
