14Remove the host with the Unresponsive status from the EMW, and select Add Storage Array to add the host again.

15If the host does not return to Optimal status, go to step 16.

16Ensure that the host is turned on and operational and that the host adapters have been installed.

17Check all external cables and switches or hubs to make sure that no visible damage exists and that they are securely connected.

18Make sure the host context agent software is installed and running.

If you started the host system before you were connected to the RAID controller module in the storage array, the host context agent software is not able to detect the RAID controller modules. If this is the case, make sure that the connections are secure, and restart the host context agent software.

19If you have recently replaced or added the RAID controller module, restart the host context agent software so that the new RAID controller module is recognized.

20If the problem still exists, make the appropriate host modifications, check with other administrators to see if a firmware upgrade was performed on the RAID controller module from another storage management station.

If a firmware upgrade was performed, the EMW on your management station might not be able to locate the new AMW software needed to manage the storage array with the new version of the firmware.

21If the problem persists contact your Technical Support representative.

22Determine if there is an excessive amount of network traffic to one or more RAID controller modules.

This problem is self-correcting because the EMW software periodically retries to establish communication with the RAID controller modules in the storage array. If the storage array was unresponsive and a subsequent try to connect to the storage array succeeds, the storage array becomes responsive.

For an out-of-band managed storage array, determine if management operations are taking place on the storage array from other storage management stations. A RAID controller module-determined limit exists to the number of Transmission Control Protocol/Internet Protocol

MD3200i, MD3220i specifications

The Dell MD3220i and MD3200i are part of Dell's extensive line of modular storage solutions, designed to support organizations in optimizing their data management and scalability requirements. These models offer reliable performance and flexible features, making them suitable for various workloads including virtualization, cloud storage, and disaster recovery.

One of the standout features of the MD3220i and MD3200i is their support for iSCSI storage networking. By utilizing the Internet Small Computer Systems Interface (iSCSI) protocol, these systems provide organizations with a cost-effective way to connect their storage over existing network infrastructure, enabling efficient data transfers and management.

Both models are equipped with dual controllers that ensure high availability and failover capabilities, which are crucial for meeting uptime requirements in mission-critical environments. The dual controllers also facilitate load balancing and increase overall system performance, as they allow multiple paths to the storage, enhancing I/O performance.

Scalability is another key characteristic of the MD3220i and MD3200i. These storage arrays can be expanded to meet growing storage demands, supporting up to 240TB of raw capacity with up to 16 additional expansion enclosures. This flexibility allows organizations to start with a smaller configuration and grow their storage capabilities without a complete overhaul of the existing infrastructure.

The units also support multiple disk types, including traditional spinning disks, solid-state drives (SSDs), and a combination of both. This versatility enables users to tailor storage configurations to their specific performance and budgetary needs. Furthermore, the systems feature advanced data management technologies such as snapshots and remote replication, providing essential tools for data protection.

With their ease of management, the MD3220i and MD3200i are designed for straightforward configuration and operation. The intuitive management interfaces allow IT professionals to monitor performance, configure storage, and manage data effectively, ensuring businesses can maintain optimal system availability.

In summary, the Dell MD3220i and MD3200i are robust, scalable, and versatile storage solutions that cater to diverse organizational needs. Their integrated technologies, such as iSCSI support, dual controller architecture, and advanced data management features, make them an ideal choice for modern data centers looking to enhance storage capabilities while ensuring reliability and performance.
