Installing and Using the Navisphere Host Agent or Server Utility

17.If you installed a new version of the Host Agent and will be using Event Monitor, refer to Using the Event Monitor configuration file on page 3-11.

If you updated the Host Agent and were using Event Monitor, restore the Event Monitor configuration from a previously copied Navimon.cfg file:

a.Stop the Agent, as described on page 3-13, Stopping the Host Agent service.

b.Move or copy the saved Navimon.cfg to the real Navimon.cfg file, as described on page 3-12, Starting the Host Agent service.

c.Start the Agent, as described on page 3-12, Starting the Host Agent service.

18.If you are managing pre-FC4700 storage systems, you must edit the Host Agent configuration file to add device entries for each storage system the server will communicate with. To edit the Host Agent configuration file use one of the following:

•the Remote Agent Configuration feature of Manager as described in the EMC Navisphere Manager Administrator’s Guide.

•the CLI remoteconfig command as described in the Navisphere Command Line Interface (CLI) Reference Manual.

When a pre-FC4700 storage system experiences heavy input/output traffic (that is, applications are using the storage system), information may not be reported to the Host Agent in a timely manner. In such a situation, the Host Agent may take several minutes to execute a storage-system management task. This behavior is most evident when one Host Agent is managing multiple storage systems. Also, if the SP event log is large and the Host Agent configuration file is set up to read all the events, it may take a few minutes for the Host Agent to start.

19.If you have an iSCSI configuration with a multi-homed server (multiple NIC cards installed on the server), and are running Windows Server 2003 or Windows 2000, do the following to ensure that the Agent finds the correct NIC card:

a.Create a text file in the Host Agent directory and name it agentid.txt.

b.Open the agentid.txt file and on the first line, type the fully qualified domain name of the host that you want to display in Navisphere.

CLARiiON specifications

EMC CLARiiON is a storied name in the realm of data storage solutions, renowned for its reliability, scalability, and advanced features. As a part of EMC's pioneering approach to enterprise storage, CLARiiON systems are designed to meet the demands of businesses ranging from small enterprises to large data centers.

One of the standout features of EMC CLARiiON is its support for both Fibre Channel and iSCSI protocols, which allows for versatile deployment options in various network environments. This dual-protocol capability is key in enabling organizations to leverage existing network infrastructures while providing the flexibility to scale as needed.

The architecture of CLARiiON is built on a modular design, featuring a series of storage processors, also known as storage controllers. This design not only enhances performance but also allows for easy upgrades and expansions. The use of RAID (Redundant Array of Independent Disks) technology ensures data redundancy and integrity, offering a variety of RAID levels to cater to specific performance and data protection needs.

EMC CLARiiON also integrates advanced data management features such as online capacity expansion, which enables administrators to add drives without disrupting operations. This is complemented by the system's support for thin provisioning, which allows for more efficient use of storage space, presenting only the amount of storage that is actually being used.

One notable technology employed by CLARiiON is the Storage Resource Management (SRM) suite, which provides powerful tools for monitoring, reporting, and managing storage usage and performance. This suite enables IT teams to optimize their storage investments by identifying trends and potential issues before they affect service levels.

Another critical aspect is the inclusion of automatic load balancing features, which help distribute workloads evenly across available storage resources. This promotes optimal performance and reduces the risk of bottlenecks during peak usage times. Additionally, the snapshot technology embedded in CLARiiON offers users the ability to create point-in-time copies of data, facilitating rapid recovery in the event of data loss or corruption.

Lastly, EMC CLARiiON systems are designed with high availability in mind. They often feature redundant components and advanced failover capabilities to ensure seamless operations. With these characteristics, EMC CLARiiON stands as a robust solution for organizations seeking to enhance their data storage strategy, driven by cutting-edge technology and tailored to meet diverse business requirements.
