Fatal Error or Data Corruption Reported

Issue: Fatal error(s) or data corruption(s) are reported when accessing virtual disks.

Corrective Action: Contact Dell Technical Support.

Physical Disk Displayed as Blocked

Issue: One or more physical disks is displayed as Blocked and can not be configured.

Corrective Action: Update the PERC cards to the latest firmware available on support.dell.com.

Multiple Disks Become Inaccessible

Issue: Rebuilding the physical disks after multiple disks become simultaneously inaccessible.

Corrective Action: Multiple physical disk errors in a single array typically indicate a failure in cabling or connection and could involve the loss of data. You can recover the virtual disk after multiple physical disks become simultaneously inaccessible. Perform the following steps to recover the virtual disk:

CAUTION: Follow the safety precautions to prevent electrostatic discharge.

1Turn off the system, check cable connections, and reseat physical disks.

2Ensure that all the disks are present in the enclosure.

3Turn on the system and enter the BIOS Configuration Utility (<Ctrl><R>) utility.

4Import the foreign configuration.

Press <F> at the prompt to import the configuration, or press <C> to enter the BIOS Configuration Utility (<Ctrl><R>) and either import or clear the foreign configuration.

Dell H310 Fatal Error or Data Corruption Reported, Physical Disk Displayed as Blocked, Multiple Disks Become Inaccessible

H310, H710, H710P, H810 specifications

Dell offers a range of storage controller technologies, notably the H810, H710, H710P, and H310, which cater to different enterprise needs. These controllers are designed to support various storage configurations, enhancing overall system performance and reliability.

The Dell H810 is a high-performance PCIe 3.0 RAID controller that supports up to eight internal drives and is particularly suited for demanding workloads. It features advanced RAID levels including RAID 0, 1, 5, 6, 10, 50, and 60, providing flexibility for various data protection strategies. The H810 also supports up to 32TB of storage capacity, making it suitable for environments that require substantial data management capabilities.

The H710 is another powerful RAID controller, widely recognized for its balance of performance and cost-efficiency. It features 1GB of cache memory, which aids in accelerating read and write operations. The H710 supports the same RAID levels as the H810 and allows for up to 512MB of non-volatile memory. This ensures data integrity even in the event of a power failure, making it reliable for critical applications.

The H710P is an enhanced version of the H710, with a significant upgrade in its cache capabilities. It offers 2GB of battery-backed cache memory, further enhancing data processing speeds and improving responsiveness. The H710P is ideal for intensive workloads and virtualization, where rapid access to data is essential. This controller also includes features such as RAID storage pooling, intelligent data tiering, and support for multiple virtual disks.

Finally, the H310 is a cost-effective option for small to medium-sized businesses or those with less demanding storage requirements. It offers similar RAID support as the higher-end controllers but operates with a simpler architecture. The H310 features 512MB of cache, providing sufficient performance for regular workloads without the additional complexities of more advanced controllers.

In summary, Dell's H810, H710, H710P, and H310 storage controllers each serve distinct purposes, providing various features, technologies, and performance characteristics tailored to different business needs. From high-capacity storage solutions to user-friendly setups, Dell’s offerings ensure that organizations can efficiently manage their data storage requirements.
