Physical Disk Fails During Reconstruction On Redundant Virtual Disk

Issue:

A physical disk fails during a reconstruction process on a redundant virtual disk that has a hot

 

spare.

Corrective

The dedicated hot spare goes to Ready state and the virtual disk goes to Failed state.

Action:

 

Virtual Disk Fails Rebuild Using A Dedicated Hot Spare

Issue:

A virtual disk fails during rebuild while using a dedicated hot spare.

Description:

The dedicated hot spare goes to Ready state and the virtual disk goes to Failed state.

Physical Disk Takes A Long Time To Rebuild

Issue:

A physical disk is taking longer than expected to rebuild.

Description: A physical disk takes longer to rebuild when under high stress. For example, there is one rebuild I/O operation for every five host I/O operations. You cannot add a second virtual disk to a disk group while the virtual disk in that disk group is undergoing a rebuild. The firmware does not allow you to create a virtual disk using the free space available in a disk group if a physical disk in a virtual disk group is undergoing a rebuild operation.

SMART Errors

SMART monitors the internal performance of all motors, heads, and physical disk electronics and detects predictable physical disk failures.

NOTE: For information about where to find reports of SMART errors that could indicate hardware failure, see the Dell OpenManage storage management documentation at dell.com/support/manuals.

Smart Error Detected On A Physical Disk In A Redundant Virtual Disk

Issue:

A SMART error is detected on a physical disk in a redundant virtual disk.

Corrective

Perform the following steps:

Action:

1.

Back up your data.

 

 

2.

Force the physical disk offline.

NOTE: If a hot spare is present, the rebuild starts with the hot spare after the disk is forced offline.

3.Replace the disk with a new physical disk of equal or higher capacity.

4.Perform the Replace Member operation.

NOTE: The Replace Member operation allows you to copy data from a source physical disk of a virtual disk to a target physical disk that is not a part of the virtual disk. For more information about the Replace Member feature, see the topic Using Replace Member And Revertible Hot Spares.

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.
