05-Configuring a P430 storage controller

Configuring a RAID-P430-M1 or RAID-P430-M2 storage controller

About RAID-P430-M1 and RAID-P430-M2 storage controllers

The RAID-P430-M1 and RAID-P430-M2 storage controllers support 6-Gbps and 12-Gbps SAS/SATA data channels and caching, which greatly increases performance and data security. For more information about storage controller details and the supported cache, contact Technical Support.

Features

Operating modes

The storage controller supports the following operating modes:

·     RAID: expose raw modeThis is the default mode. In this mode, the system can identify and assign drive letters to both raw drives and member drives of RAID arrays.

·     RAID: hide raw modeIn this mode, the system can identify and assign drive letters only to member drives of RAID arrays. Raw drives cannot be identified or used by the operating system.

·     HBA mode—In this mode, physical drives are exposed as raw drives and RAID functions are disabled.

·     Auto Volume mode—In this mode, physical drives with system partitions are exposed as raw drives. Physical drives without system partitions are configured as simple volumes.

·     Simple Volume mode—In this mode, only non-redundant RAID arrays with the simple volume level (each contains only one drive) can be created. RAID arrays with other RAID levels cannot be created.

 

 

NOTE:

Raw drives refer to drives that do not have RAID configuration.

 

Before you configure RAID in RAID: expose raw or RAID: hide raw mode or set the controller operating mode to auto volume or simple volume mode, you must initialize target drives.

Before you configure the controller to operate in RAID: expose raw mode without RAID configuration or in HBA mode, you must uninitialize target drives.

For the new mode to take effect, restart the server after an operating mode change.

The operating system might fail to start up after the operating mode of the storage controller is changed. To resolve the issue, you can re-install the operating system. If the issue persists, contact Technical Support.

RAID levels

The supported RAID levels vary by storage controller model. For more information about the supported RAID levels of each storage controller, see H3C Servers Storage Controllers Technical Specifications.

Table 1 shows the minimum number of drives required by each RAID level and the maximum number of failed drives supported by each RAID level. For more information about RAID levels, see "Appendix B  RAID arrays and fault tolerance."

Hot spare drives

You can configure hot spare drives to improve data security. A hot spare drive is a standby drive that does not store any data. When a drive in a redundant RAID fails, a spare drive automatically replaces the failed drive and rebuilds the data of the failed drive.

The storage controller supports the following types of hot spare drives. For more information about hot spare drive types, see "Storage controller features."

·     Global spare drive.

·     Dedicated spare drive.

·     Pooled spare drive.

Restrictions and guidelines for configuring RAID

·     As a best practice, configure RAID with drives that do not contain RAID information.

·     To build a RAID successfully and ensure RAID performance, make sure all drives in the RAID are the same type (HDDs or SSDs) and have the same connector type (SAS or SATA).

·     For efficient use of storage, use drives that have the same capacity to build a RAID. If the drives have different capacities, the lowest capacity is used across all drives in the RAID.

·     If you use one physical drive to create multiple RAIDs, RAID performance might decrease in addition to increased maintenance complexities.

High speed read/write cache

For the RAID-P430-M1 and RAID-P430-M2 storage controllers, you can enable caching on the storage controller by using ARCCONF commands. For more information, contact Technical Support.

Uninitializing drives

IMPORTANT

IMPORTANT:

When the storage controller operating mode is HBA, you cannot uninitialize drives. To uninitialize these drives, you must first set the storage controller operating mode to RAID: hide RAW, RAID: expose RAW, Auto Volume, or Simple Volume.

 

Perform this task to clear data, Adaptec metadata, and reserved space on drives, and remove the system partitions. After a drive in Ready state is uninitialized, it returns to the raw state.

To uninitialize drives:
