08-Configuring an H460, P460, P240 or P4408 storage controller

Configuring an H460, P460, P2404, or P4408 series storage controller

About H460, P460, P2404, and P4408 storage controllers

The storage controllers support 12-Gbps data channels. Some storage controllers support caching, which greatly improves performance and data security. For more information, contact Technical Support.

This chapter is available for the following storage controllers:

·     HBA-H460-M1

·     HBA-H460-B1

·     RAID-P460-M2

·     RAID-P460-B2

·     RAID-P460-M4

·     RAID-P460-B4

·     RAID-P2404-Mf-4i

·     RAID-P4408-Mf-8i

·     RAID-P4408-Ma-8i-2GB

Features

Operating modes

The storage controller supports the following operating modes:

·     HBA mode—In this mode, physical drives attached to the storage controller are exposed as raw drives and RAID functions are disabled.

·     RAID mode—In this mode, RAID functions are enabled and RAID arrays can be created on physical drives. Only logical drives are exposed to the operating system.

·     Mixed modeThis is the default mode. In this mode, RAID functions are enabled and RAID arrays can be created on physical drives. Both logical drives and raw physical drives are exposed to the operating system.

 

IMPORTANT

IMPORTANT:

·     If the storage controller has RAID configuration, you must clear RAID configuration before changing the operation mode of the storage controller to HBA mode. The new operating mode takes effect after the server reboots.

·     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 this issue, reinstall 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."

·     Dedicated spare drive.

·     Auto replace spare drive.

Restrictions and guidelines for RAID configuration

As a best practice, install drives that do not contain RAID information.

To avoid degraded RAID performance or RAID creation failures, 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 one drive is used by several logical drives, RAID performance might be affected and maintenance complexities will increase.

Deleting a RAID array

This task allows you to delete a RAID array and the logical drives contained in it.

 

 

NOTE:

Deleting logical drives in the middle of a RAID array might cause discontinuous sectors on the physical drives of this array. As a consequence, the operation might affect the drive read and write rate and limit the operations on logical drives performed by using RAID array configuration tools. As a best practice to avoid these problems, delete logical drives from back to front in sequence. If you delete logical drives in the middle, wait for all the logical drives to enter normal state before executing any other operations.

 

To delete a RAID array:

1.     On the storage controller configuration screen as shown in Figure 23, select Array Configuration and press Enter.

Figure 23 Storage controller configuration screen

 

2.     On the screen as shown in Figure 24, select Manage Arrays and press Enter.
