Troubleshooting RAID Controller Modules

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

CAUTION: In the case of non-redundant configurations, it is recommended that you turn off the host server before turning off the array to prevent loss of data.

•If the array status LED is solid or blinking amber:

a In the AMW, select the Summary tab, and click on Storage Array needs attention. Follow the listed procedures in the recovery guru(s) and wait for up to 5 minutes to check if the LED has turned blue. See "Recovery Guru" on page 232.

b If following the recovery guru procedures does not solve the problem, complete the following procedure to further troubleshoot the array.

c Turn off the host server as appropriate.

d Remove the RAID controller module and verify that the pins on backplane and RAID controller module are not bent. See "Removing a RAID Controller Module Blank" on page 205.

e Reinstall the RAID controller module and wait for 30 seconds. See "Installing a RAID Controller Module" on page 208.

f Check the RAID controller module status LED. g Replace the RAID controller module.

h Turn on the host server.

If the problem is not resolved, see "Getting Help" on page 259.

•If the link status LEDs are not green, see "Troubleshooting Array and Expansion Enclosure Connections" on page 255.

a Turn off the server, storage array, and expansion enclosures.

b Reseat the RAID controller module and reconnect cables on the storage array and the server.

c Restart the storage array and wait until array is fully booted. d Turn on the server.

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.
