ping <host-name-or-IP-address-of-the-host>.

If the network can access the host, continue to step c. If the network cannot access the host, skip to step d.

cRemove the host with the unresponsive status from the MDSM, and add that host again.

If the host returns to optimal status, you have completed this procedure.

dMake sure that the power to the host is turned on and that the host is operational.

eIf applicable, make sure that the host bus adapters have been installed in the host.

fExamine all external cables and switches or hubs to make sure that you cannot see any damage and that they are tightly connected.

gIf you have recently replaced or added the controller, restart the host context agent software so that the new controller is found.

If a problem exists, make the appropriate modifications to the host.

4If you have an out-of-band storage array, use the following procedure. Click Refresh after each step to make sure of the results:

aMake sure that the network can access the controllers by using the ping command. Use the following syntax:

ping <controller-IP-address>.

If the network can access the controllers, continue to step b. If the network cannot access the controllers, skip to step c.

bRemove the storage array with the unresponsive status from MDSM, and add that storage array again.

If the storage array returns to optimal status, you have completed this procedure.

cExamine the ethernet cables to make sure that you cannot see any damage and that they are tightly connected.

dMake sure that the applicable network configuration tasks have been done (for example, the IP addresses have been assigned to each controller).

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.
