Configuring an LSI-9660 series storage controller

NOTE:

The BIOS screens might vary by the BIOS version. The screenshots in this chapter are for illustration only.

About LSI-9660 series storage controllers

The storage controllers provide a maximum interface rate of 24 Gbps, and some storage controllers support caching, which greatly increases performance and data security. For more information about storage controller details and the supported cache, access http://www.h3c.com/cn/home/qr/default.htm?id=315.

This chapter is applicable to the RAID-LSI-9660-LP-16i-4GB storage controller.

RAID levels

The supported RAID levels vary by storage controller model. For more information about the supported RAID levels of each storage controller, contact Technical Support.

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."

Table 1 RAID levels and the numbers of drives for each RAID level

RAID level	Min. drives required	Max. failed drives
RAID 0	1	0
RAID 1	2	Number of drives divided by 2
RAID 5	3	1
RAID 6	4	2
RAID 10	4	n, where n is the number of RAID 1 arrays in the RAID 10 array.
RAID 50	6	n, where n is the number of RAID 5 arrays in the RAID 50 array.
RAID 60	8	2n, where n is the number of RAID 6 arrays in the RAID 60 array.

NOTE:

Storage controllers described in this chapter support using a maximum of eight member RAID 1/5/6 arrays to form a RAID 10/50/60 array.

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.

Figure 19 Configuring RAID parameters

Table 3 Parameter description

Parameter	Description
Virtual Drive Name	RAID array name, a case-insensitive string of letters, digits, and special characters.
Virtual Drive Size	Capacity for the RAID array.
Virtual Drive Size Unit	Capacity unit for the RAID array.
Strip Size	Strip size of the RAID array, that is, data block size for each drive. For logical drives of SSDs, a strip size of 64 KiB is supported. For logical drives of HDDs, the supported strip sizes are 64 KiB and 256 KiB.
Read Cache Policy	Read cache policy: · Read Ahead—Enables read ahead capability. When this capability is enabled, the storage controller can pre-read sequential data or anticipate data to be requested and store the data in the cache · No Read Ahead—Disables read ahead capability. NOTE: a The read ahead feature is available only for logical drives of HDDs that are configured in Write Back mode. This feature is not available for logical drives of SSDs. It does not take effect even when you set the SSD-based logical drive to Read Ahead and the cache policy will display No Read Ahead. b The read ahead feature will be disabled during recovery processes at the back end, including rebuilding, copyback, and online scale-up of logical drives.. c When the supercapacitor is damaged, logical drives in Write Back mode will switch to Write Through mode, and the read ahead feature will be disabled.
Write Cache Policy	Write cache policy: · Write through—Enables the controller to send data transfer completion signal to the host when the physical drives have received all data in a transaction. · Write back—Enables the controller to send data transfer completion signal to the host when the controller cache receives all data in a transaction. If the supercapacitor is faulty or no supercapacitor is present, the write cache policy will automatically switch to Write through mode. · Always write back—Uses the Write back policy forcedly. Even if the supercapacitor of the storage controller is absent or faulty, it will not switch to Write through mode. If the server is powered off, the controller cache loses its data because of lack of power. As a best practice, select this option with caution.
Drive Write Cache Policy	Drive cache policy: · Enable—Enables the drive cahe policy. In this case, data is written to the cache through the drive during the write process, which improves write performance. However, data might get lost upon an unexpected power failure if additional protection mechanism is not in place. · Disable—Disables the drive cache policy. In this case, data is written to the cache without passing through the drive during the write process. Data will not get lost upon an unexpected power failure. · Default—Maintains the current drive cache policy.
Disable Background Initialization	Enabling status of background initialization.
Initialization	Default initialization mode: · No. · Fast. · Full.
Save Configuration	Select this option to save the configuration.

Restrictions and guidelines

· Before performing online expansion, back up the data on the logical drive to be expanded as a best practice.

· Do not restart the system during the online expansion.

· Do not remove logical drive members during online expansion. If you fail to do so, data loss might occur.

· When a storage controller is performing online expansion, the logical drive setup feature is disabled.

· Online expansion is not supported in the following scenarios:

¡ The array to which the target logical drive belongs has multiple logical drives.

¡ The target logical drive does not start from the beginning of the array.

¡ The target logical drive is performing initialization, secure erase, consistency check, rollback, or rebuilding.

¡ The storage controller is performing an expansion operation by adding new physical drives.

Using unused drive space in the array

NOTE:

· Drive space expansion by using unused drive space in the array is available only for RAID levels 0, 1, 5, and 6 in UEFI mode or in the OS.

· After RAID levels 0, 1, 5, and 6 uses unused drive space for expansion, the background initialization starts immediately.

Importing foreign configuration

Perform this task to import the configuration of an old storage controller to a new storage controller after the old storage controller is replaced.

Restrictiond and guidelines

After you replace a storage controller on a server configured with RAID, the system identifies current RAID configuration as Foreign Configuration. In this case, if you clear foreign configuration, the RAID configuration will get lost.

When the number of failed or missing drives exceeds the maximum allowable by a RAID array, the RAID array cannot be imported successfully.

The RAID configuration of the LSI MR96 storage controller is mutually exclusive with configurations of the LSI MR93, LSI MR94, and LSI MR95 controllers, preventing the import of external configuration information between them.

Procedure

Updating the storage controller firmware

Perform this task to update the firmware of a storage controller by a firmware file of a higher, lower, or the same version.

Syntax

storcli2 /ccontroller_Index download file= fw_file [activationtype=online|offline] [noverchk]

Parameters

controller_id: Specifies the index of a storage controller. If only one storage controller exists, the ID is 0 by default. If multiple storage controllers exist, use the storcli2 show command to view the controller index.

fw_file: Specifies the firmware file name.

activationtype: Specifies the method to activate the storage controller firmware image after it is downloaded. If you do not specify this keyword, the online method is used.

· online: Activates the firmware image online. The storage controller will not respond to I/O requests before the activation is completed.

· offline: Activates the firmware image offline. If you select this method, you must restart the server for the new firmware image to take effect.

noverchk: Configures the system not to check the firmware image version. This keyword is required when you downgrade the storage controller firmware or update the storage controller firmware to the same version before the update.

Usage guidelines

If the firmware file does not exist in the current path, you must add the absolute path to the file name.

Online firmware activation will prevent the storage controller from responding to I/O requests before the firmware is fully activated. This impacts responses to upper-level services.

vd_drives: Specifies member drives. The name of each member drive must be in the enclosure_id:slot_id format, where enclosure_id represents the persistent ID of the enclosure in which the drive resides, and slot_id represents the drive slot number.

pdperarraynum: Specifies the number of drives in the sub-group if the RAID level is 50 or 60.

pdcache_policy: Specifies the cache state for member drives. Options include on, off, and default. Setting this field to default represents retaining the current cache state.

wt|wb|awb: Specifies the write cache policy. Write through (wt) notifies the system of transmission completion when data are written into disks. Write back (wb) notifies the system of transmission completion when data are written into the controller cache. Always write back (awb) forces the system to use write back even when no supercapacitor is present, which may cause data loss in the event of unexpected power-off.

nora|ra: Specifies the read cache policy. When reading data from RAID, the ra policy enables the system to read the surrounding data and store them in the cache at the same time. When the user accesses these data subsequently, they can be directly read from the cache, which reduces the disk seeking time and improves read performance.

strip_size: Specifies the strip size. Options include 64 and 256. For an SSD controller, only 64 is supported. For an HDD controller, 64 and 256 are supported.

spares_drives: Specifies hot spare drives. The name of each hot spare drive is in the format of enclosure_id:slot_id.

raid_id: Specifies the ID of the RAID array to be deleted. To obtain the ID, use the ./storcli2 /c0/vall show command. If you specify this argument as all, the command deletes all the RAID arrays.

Usage guidelines

When you specify member drives, use a comma (,) to separate two slots and use a hyphen (-) to indicate a slot range.
