2 Product description Product description The EMC Navisphere Storage Processor (SP) Agent is storage-system software that allows a Navisphere client application (such as Navisphere Manager or Navisphere CLI) to communicate with FLARE software in an AX-series storage system. The SP Agent is an application with no direct user interface. You configure and control the SP Agent through the Remote Agent Configuration feature of Navisphere Manager and CLI. Several Navisphere clients can communicate with one Navisphere SP Agent running on one SP in a storage system. New features and changes This section describes any new features - enhancements to existing functionality or added functionality - and changes for this release of the product. Support for AX150-series storage systems Environment and system requirements Hardware FLARE software This section identifies the hardware and software requirements for proper operation of this release of the SP Agent. The minimum hardware requirement is an AX150-series storage system. FLARE Operating Environment (OE) version yyy is required for AX150-series storage systems. Navisphere management software requirements Fixed problems Navisphere Manager version 6.20.xx.xx.xx is required for the AX150- series storage systems.

3 Known problems and limitations Known problems and limitations Problem area and description Visit the EMC Powerlink Issue Tracker website at for the most recent updates and information on previous Navisphere SP Agent releases. NDU failure due to problems writing to the event log. The agent logs an event in the application log if it encounters an error when trying to write to the Event Monitor Log. The error logged in the application log is EM_EventLog::WriteLog - Error Writing Event. The agent then terminates and as a result the NDU fails. [116046] You cannot not create an incremental copy session with a source LUN that is currently active. [109454] The loopback address that a client uses is equivalent to the local hostname or IP address, independent of any "-a" options used when invoking the agent. When a hot spare is replaced with another drive of same or larger capacity, the new drive's properties should be displayed in the hot spare properties. Instead the old drive's properties are displayed.[125157] If you have an off-array CIMOM on the same management station as the central agent and you stop the agent to add the user privileges into the agent.config file and restart it, the off-array CIMOM will not know about the new user entries you just added. [127726] While you try to install a software update with CLI you see the following error: Error: NDU command failed Error returned from Agent User connect attempt timed out. An inspection of the logs indicates the agent logged the following message: Agent Closing Log File -- Too many consecutive exception events. To prevent an overflow of messages in the application event logs, the logging is turned off and no further events are logged until the socket is reset again and the agent is communicating. The agent is still up and can be connected to once the socket gets reset. [127776] Work-around The primary SP for the NDU must be rebooted. Wait until the active session completes and try again. None. None. The user has to stop the NaviGovernor and restart it to make the CIMOM aware of the changes in the user privileges. This is a result of a transient network condition. Try the operation again. 3

4 Technical notes Technical notes Software upgrades Polling of FLARE This section includes important information that does not appear anywhere else. For an AX-series storage system, the SP Agent is an integral part of the AX-series storage-system software called the FLARE Integrated Operating Environment software. An upgrade to the SP Agent is available only as a new version of the AX-Series FLARE Integrated Operating Environment software. The SP Agent is in degraded mode when a poll (a get operation) of FLARE returns any error. When a set operation, such as binding a LUN, returns an error, the SP Agent does not go to degraded mode. When the AX-series SP Agent is in degraded mode, Navisphere Manager displays an F on the storage system icon, and the following message appears in the Event Log: INTERNAL: Poll failure: agent going into degraded mode: 4

5 Documentation Documentation In this situation, only the following functions are guaranteed to work: Retrieval of event log messages File Transfer Manager functionality of the SP Agent Software installation (only if the SP software allows it) Rebooting the SP (for peer or both SPs) The following table lists the documents with information on reinstalling and configuring the SP Agent: Part Number Description EMC Navisphere Manager Administrator's Guide EMC Navisphere Command Line Interface (CLI) Reference EMC AX100-Series Integrated Management Software Version yyy Release Notes EMC AX150-Series Integrated Management Software version yyy Release Notes These manuals can be found on the EMC Navisphere Manager Upgrade Documentation CD that shipped with the Navisphere Manager upgrade kit or on the AX100-series or AX150-series support website. 5

6 Software media, organization, and files Software media, organization, and files The following table lists the applicable documentation media for this release: Part Number Description For AX100-series storage systems - EMC CLARiiON Storage-System Hardware and Software Documentation CD For AX150-series storage systems - EMC Navisphere Manager Upgrade Documentation CD Installation AX-series storage systems ship from the factory with the latest version of the SP Agent installed on each SP. Since the SP Agent is an integral part of the FLARE Integrated Operating Environment on an AX-series storage system, updates to the SP Agent are integral parts of this FLARE software. To update the FLARE Integrated Operating Environment, use the software installation procedure in the EMC Navisphere Manager Administrator's Guide or the EMC Navisphere Command Line Interface (CLI) Reference. 6
