MegaRAID SAS Device Driver Installation User Guide June 2015

Chapter 2: Windows Driver Installation

This chapter describes the installation of the following Microsoft Windows OSs:
Windows 7 Client SP1 Windows 8, 8.1, 8.1 Update 1 Windows 2008 R2 SP1 Windows Server 2012 Windows Server 2012 R2 Win Server 2012 R2 Update 1

2.1 MegaRAID Primary Storage

In the MegaRAID primary storage configuration, the Windows OS is installed on virtual drives provided by the MegaRAID controller. The MegaRAID controllers (6Gb/s and 12Gb/s) include pre-boot configuration utilities (WebBIOS™ and Ctrl-R) that creates the virtual drive before the installation of the Windows OS starts.
To install the Windows OS, prepare a USB flash drive, CD-ROM or diskette, as appropriate, with the MegaRAID driver.
Windows Driver Installation
MegaRAID Primary Storage
The driver is distributed in a series of nested compressed files. Use an existing Windows device to extract the files for the driver-loading device (USB, CD-ROM, or diskette) by using the appropriate Windows driver. Only two driver choices exist across the supported Windows versions: one for 32-bit systems or one for 64-bit systems.

2.1.1 Storage Configuration

The procedures in this section describe how to create the virtual drive used for the Windows OS. You can add other virtual drives to the running OS after the Windows OS has been installed. The MegaRAID preboot BIOS utilities, such as WebBIOS (for 6Gb/s controllers) and Ctrl-R (for 12Gb/s controllers) that create the virtual disk for the Windows OS are accessible during the power-on self-test (POST) part of the bootup process.
Refer to the MegaRAID SAS Software User Guide or the 12Gb/s MegaRAID® SAS Software User Guide for more information about the WebBIOS configuration utility and the Ctrl-R Utility, respectively.
2.1.1.1 Creating Storage Configuration Using WebBIOS
The following procedure describes the creation of a RAID 1 array. You can use other RAID levels, and the steps are the same except when selecting the RAID level. In a RAID 1 array, the RAID controller duplicates all data from one drive to a second drive. The RAID 1 array provides complete data redundancy, but at the cost of doubling the required data storage capacity. It is appropriate for small databases or any other environment that requires fault tolerance but small capacity.
1. When the host computer is booting, hold down the Ctrl key and press the H key when the following text appears on the window:

Windows Driver Installation
MegaRAID Primary Storage
NOTE A RAID 1 virtual drive can contain up to 16 drive groups and up to
32 drives in a single span. (Other factors, su ch as the type of controller, can limit the number of drives.) You must use two drives in each RAID 1 drive group in the span.
13. After you finish selecting drives for the drive group, click Accept DG.
14. Click Next.
The Virtual Drive Definition window appears. You use this window to select the RAID level, strip size, read policy, and other attributes for the new virtual drives.
15. Change the virtual drive options from the defaults listed on the window as needed.
Here are brief explanations of the virtual drive options:
— RAID Level: The drop-down menu lists the possible RAID levels for the virtual drive. Select RAID 1. — Strip Size: The strip size specifies the length of the data segments that the RAID controller writes across
multiple drives, not including parity drives. For example, consider a stripe that contains 64 KB of drive space and has 16 KB of data residing on each drive in the stripe. In this case, the stripe size is 64 KB and the strip size is 16 KB. You can set the strip size to 8, 16, 32, 64, 128, 256, 512, and 1024 KB. A larger strip size produces higher

read performance. If your computer regularly performs random read requests, choose a smaller strip size. The default is 64 KB.
— Access Policy: Select the type of data access that is allowed for this virtual drive.
RW: Permit read/write access. This setting is the default.
Read Only: Permit read-only access.
Blocked: Do not permit access.
— Read Policy: Specify the read policy for this virtual drive.
Normal: Disable the read-ahead capability. This setting is the default.
Ahead: Enable read-ahead capability, which permits the controller to read sequentially ahead of requested
data and to store the additional data in cache memory, anticipating that the data will be needed soon. This setting speeds up read operations for sequential data, but little improvement exists when accessing random data.
— Write Policy: Specify the write policy for this virtual drive.
WBack: In Write Back mode, the controller sends a data transfer completion signal to the host when the controller cache has received all of the data in a transaction. This setting is recommended in Standard mode.
WThru: In Write Through mode, the controller sends a data transfer completion signal to the host when the drive subsystem has received all of the data in a transaction. This setting is the default.
Write Back with BBU: Select this mode if you want the controller to use Write Back mode, but the controller either has no battery backup unit (BBU) or the BBU is bad. If you do not choose this option, the controller firmware automatically switches to Write Through mode if it detects a bad or missing BBU.
Windows Driver Installation
MegaRAID Primary Storage
NOTE You can use Write Back mode with or without a battery. You should
use either a battery to protect the controller cache or an uninterruptible power supply (UPS) to protect the entire system. If you do not use a battery or a UPS, and a power failure occurs, you risk losing the data in the controller cache. Although you can enable or disable the disk cache, you should disable it. If you enable the disk cache, the drive sends a data transfer completion signal to the controller when the drive cache has received all the data in a transaction. However, the data has not been actually transferred to the

— IO Policy: The IO policy applies to read operations on a specific virtual drive. It does not affect the read-ahead
cache.
Direct: Read operations are not buffered in cache memory. Data is transferred to the cache and the host concurrently. If the same data block is read again, it comes from cache memory. This setting is the default.
Cached: Read operations are buffered in cache memory before they are sent to the host.
— Drive Policy: Specify the drive cache policy.
Enable: Enable the drive cache.
Disable: Disable the drive cache.
NoChange: Leave the current drive cache policy as is. This setting is the default.
— Disable BGI: Specify the background initialization status.
No: Leave background initialization enabled. A new configuration can be initialized in the background while
you use WebBIOS to perform other configuration tasks. This setting is the default.
Yes: Select Yes if you do not want to allow background initialization for configurations on this controller.
— Select Size: Specify the size of the virtual drive or drives in MB, GB, or TB. Usually, this size is the full size for the
RAID 1 array shown in the Configuration panel on the right. You can specify a smaller size if you want to create other virtual drives on the same drive group.
— Update Size: Click Update Size to update the Select Size Field value for the selected RAID levels.
16. Either click Accept to accept the changes to the virtual drive definition, or click Reclaim to return to the previous settings.
17. Click Next after you define the virtual drives.
The Configuration Preview window appears.
18. Check the information in the configuration preview.
19. If the virtual drive configuration is acceptable, click Accept to save the configuration. Otherwise, click Back to return to the previous screens and change the configuration.
20. If you accept the configuration, click Yes at the prompt to save the configuration and initialize the new virtual drive.
21. After the initialization is complete (the elapsed time depends on the RAID level and the disk size), click the Home button, and then click Exit in the left hand window frame.

9. Press Advanced.
The Create Virtual Drive – Advanced dialog appears. The following are the additional virtual drive properties that you can select while you create virtual drive. Change these parameters only if you have a specific reason for doing so. It is usually best to keep them at their default settings.
Strip Size – The strip size is the portion of the stripe that resides on a single virtual drive in the drive group. Strip
sizes of 64 KB, 128 KB, 256 KB, 512 KB, or 1 MB are supported.
Read Policy – Specify one of the following options to specify the read policy for this virtual drive:
— Normal – Read ahead capability lets the controller read sequentially ahead of requested data and to store the
additional data in cache memory, thereby anticipating that the data will be needed soon. This process speeds up reads for sequential data, but there is little improvement when the computer accesses random data.
— Ahead – Disables the read ahead capability.
Write Policy – Select one of the following options to specify the write policy for this virtual drive:
— Write Back – In this mode, the controller sends a data transfer completion signal to the host when the
controller cache receives all of the data in a transaction. If you select the Write Back policy and the battery is absent, the firmware disables the Write Back policy and defaults to the Write Through policy.
— Write Through – In this mode, the controller sends a data transfer completion signal to the host when the
drive subsystem receives all the data in a transaction.
— Always Write Back – In this mode, the controller sends a data transfer completion signal to the host when the
controller cache receives all the data in a transaction. If you select the Always Write Back policy and the battery is absent, the firmware is forced to use the Write Back policy.
I/O Policy – The I/O policy applies to reads on a specific virtual drive. It does not affect the read ahead cache.
— Cached – In this mode, all reads are buffered in cache memory. Cached I/O provides faster processing. — Direct – In this mode, reads are not buffered in cache memory. Data is transferred to the cache and the host
concurrently. If the same data block is read again, it comes from cache memory. Direct I/O makes sure that the cache and the host contain the same data.
Disk cache policy – Select a cache setting for this virtual drive:
— Enable – Enable the drive cache. — Disable – Disable the drive cache. — Unchanged – Updating the drive cache policy to Unchanged may enable /disable the drive cache based on
the WCE (Write Cache Policy) bit of the save mode page of the drive.
Emulation – Lets you to set the emulation type on a virtual drive to default or none. The force option forces the
emulation to be set on a controller even when MFC settings do not support it. The possible options are Default, Disabled, or Forced.
Initialize – Select to initialize the virtual drive. Initialization prepares the storage medium for use. Fast initialization
will be performed on the virtual drive.
Configure Hot Spare – Select to configure physical drives as hot spares for the newly created virtual drive.
This option is enabled only if there are additional drives and if they are eligible to be configured as hot spares. This option is not applicable for RAID 0. If you select this option after the Virtual drive is created, a dialog appears. The dialog asks you to choose the physical drives that you want to configure as hot spares.

If you use the MegaRAID controller as primary storage, see Section 2.1.1.1, Creating Storage Configuration Using
Installing a MegaRAID Driver on the Windows Server 2012 Operating System
WebBIOS, on configuring a virtual disk for the OS in a pre-boot environment. The Windows installation program
recognizes the MegaRAID controller, and it automatically installs a driver.
If you use the MegaRAID controller as secondary storage, Avago recommends that you install the OS without the
MegaRAID controller, shut down the system, install the controller, and let the OS automatically configure the controller with the in-box driver.
After the Windows Server 2012 OS is running on the machine with the MegaRAID controller, an upgrade to the
latest Avago MegaRAID driver is recommended. The following section describes how to upgrade the driver.

2.6.1 Upgrading the Driver for the Windows Server 2012 Operating System

Perform the following steps to upgrade the driver.
1. Download the updated driver from http://www.lsi.com/support, and put it on a USB, CD, or DVD.
2. Boot the Microsoft Server 2012 OS.
