NOTE: The replacement disk must be a hot spare or an unconfigured disk without a foreign configuration. It must have the same or greater capacity and should be of the same type as the disk it is replacing.

Restrictions and Limitations

The following restrictions and limitations apply to the Replace Member operation:

•The Replace Member functions are restricted to one per array for RAID 0, RAID 1, and RAID 5, and two per array for RAID 6.

•The Replace Member function and rebuild cannot run simultaneously on a RAID 6 virtual disk. The rebuild operation has a higher priority, and the Replace Member operation is aborted if a rebuild begins.

•The Replace Member function and rebuild cannot run simultaneously on a RAID 6 virtual disk. The rebuild operation has a higher priority, and the Replace Member operation is aborted if a rebuild begins.

Stopping Background Initialization

Background initialization (BGI) is the automated operation in which parity is created and written. BGI does not run on RAID 0 virtual disks. Under certain conditions, the BIOS Configuration Utility (<Ctrl> <R>) displays a message if you want to stop BGI in progress. An alert message is displayed if BGI is in progress and you start any of the following actions:

•A Full Initialization on the virtual disk

•A Fast Initialization on the virtual disk

•A Consistency Check on the virtual disk

The following alert message is displayed:

The virtual disk is undergoing a background initialization process. Would you like to stop the operation and proceed with the <full initialization/quick initialization/consistency check> instead?

Click Yes to stop the BGI and start the requested operation or No to allow BGI to continue.

Performing A Manual Rebuild Of An Individual Physical Disk

CAUTION: If a physical disk is a member of a disk group that contains multiple virtual disks and one of the virtual disks is deleted when a rebuild operation is in progress, the rebuild operation stops. You can then resume the rebuild operation manually using a storage management application. To avoid interruption, ensure that none of the virtual disks are deleted until the rebuild is complete.

Use the following procedures to rebuild one failed physical disk manually.

1.Press <Ctrl> <N> to access the PD Mgmt screen.

A list of physical disks is displayed. The status of each disk is displayed under the heading State.

2.Press the down-arrow key to highlight a physical disk that has a failed state.

3.Press <F2> to display a menu of available actions.

The Rebuild option is highlighted at the top of the menu.

4.Press the right-arrow key to display the rebuild options and select Start.

5.After you start the rebuild, press <Esc> to display the previous menu.

NOTE: You can also use the VD Mgmt screen to perform a manual rebuild. Use the arrow key to highlight a physical disk, and press <F2>. In the menu that is displayed, select the Rebuild option.

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.
