Provides step-by-step instructions for configuring RAID units if you have just installed the controller. Describes how to install drivers for the 3ware controller if you have just installed and configured it. Unit refers to one or more disks configured through 3ware to be treated by the operating system as a single drive. Also known as an array. Array and unit are used interchangeably throughout this manual. It includes the following sections: “Product Features”. It requires the following: Internet Explorer 5.5 and later or Mozilla 1.2 or later JavaScript must be enabled. Requires a minimum of two drives. With TwinStor technology, read performance is twice the speed of a single drive during sequential read operation. Please note that if two or more drives in a RAID 5 set fail, then all of the data will be lost. www.3ware.com. Like disks in other RAID configurations, single disks contain 3ware Disk Control Block (DCB) information and are seen by the OS as available units. For details about working with 3DM, see “3ware Disk Manager (3DM 2)” on page 65. When write cache is enabled, data will be stored in system cache, 3ware controller cache, and drive cache before the data is committed to disk. This allows the system to process multiple write commands at the same time, thus improving performance. However when data is stored in cache, it could be lost if a power failure occurred. StorSave Profiles performance that is desired for a unit when write cache is enabled (9550SX controllers only). For more information, see “Setting the StorSave Profile for a Unit” on page 139.

Set Up Management and Maintenance Features 3ware RAID controllers come with software that include a number of features to help you manage and maintain the controller and your configured units. The default settings for these features allow you to begin using your newly configured units right away. Normally your 3ware configuration remains on-screen for just a few seconds. However, if a unit has degraded, the screen indicates the problem and remains on your screen longer. The Create Disk Array screen appears (see Figure 9). www.3ware.com Basic Steps for Creating a Unit. Striping size is not applicable for RAID 1, because it is a 3ware 9550SX Serial ATA RAID Controller User Guide. The unit is not actually created and no data is overwritten until you have finished making all your changes and press F8. www.3ware.com Basic Steps for Creating a Unit. Type s to specify that the selected drive will be the hot spare. You’ll see the words “Hot Spare” appear next to the drive in the Available Drives list. Figure 13. Hot Spare Indicated www.3ware.com Specifying a Hot Spare. If you will install your OS on a disk or unit attached to the 3ware RAID controller, specify the controller as the boot device. (Note that if you configured more than one unit, the drive(s) specified as Unit 0 will be treated as the boot disk.) For details, turn to Chapter 4, “Driver Installation.” After installing the driver, you may also want to install 3ware’s browser-based Disk Management tool, 3DM 2, or the 3ware Command Line Interface (CLI). If the unit you have created will be your system's boot device, you install the driver for the controller as you install the operating system. It is recommended that you upgrade to the latest service pack available. A drive or unit managed by the 3ware RAID controller may be configured to be your system’s boot device. Or, you can use another device as your boot device, such as a disk attached to the motherboard.http://kvarkeno56.ru/userfiles/bosch-injection-pump-repair-manual.xml To create a driver diskette Insert the 3ware software CD into your system. This wizard guides you in installing the 3ware driver (see Figure 18). Note that you will see screens for the installation of two drivers during this process. Remove the driver diskette or CD, reboot the system, and log in as the system administrator. Or, you can use another device as your boot device, such as a disk attached to the motherboard. If Linux is already installed on another device, you may install the 3ware driver from either the 3ware software CD-ROM or make a driver diskette. A confirmation window opens. Insert a blank diskette into a drive and click the Yes button to begin creating the driver floppy diskette. Installing the 3ware Driver on a Red Hat Linux System that Boots From a Different Device The steps for installing the 3ware driver vary slightly, depending on your specific installation requirements. Mount the CD which contains the 3ware driver. To mount the CD, type:. The 3ware driver will be loaded from the ram disk automatically at boot time. To install the 3ware driver and load the driver manually instead of using a RAM disk Log in as root and open a console window. If Linux is already installed on another device, you may install the 3ware driver from the 3ware software CD-ROM. Click OK and continue with the installation.

Note: insert an MS-DOS floppy with the 3ware driver, the floppy drive. If you do not insert it immediately, the sysinstall may fail to recognize the floppy drive.

Normally your 3ware configuration remains on-screen for just a few seconds.http://www.drupalitalia.org/node/67897 However, if a unit has degraded, the screen indicates the problem and remains on your screen longer. For detailed information, see the version of the 3ware Escalade ATA RAID Controller User Guide that supports the 7000 and 8000 series controllers. If you have two 9000 controllers that have different versions of the BIOS installed, they will also appear in different BIOS summaries, and will launch different versions of 3BM.

If the 3ware RAID controller fails to respond to the device driver within a reasonable amount of time, the device driver may issue a soft reset to the 3ware RAID controller and retry the command packet. If the system loses power or is reset without going through the normal shutdown procedure, it is possible that the data on a redundant array may be out of synchronization. If the drive returns an error to the 3ware RAID controller, the user is notified by this AEN. If a failure of any drive is determined to be likely, the user is notified by this AEN. 3ware recommends that you replace any drive that has the SMART attribute exceeded. It will then use this data to force the failing drive to reallocate the bad sector, which essentially repairs the sector. If an array that was created on a very old 3ware product is connected to a newer 3ware RAID controller, this AEN is posted and the 3ware RAID controller rejects the drive. The replacement drive must be equal to or greater capacity than the drive it's replacing. This AEN indicates that an unsupported drive was detected during rollcall or a hot add. This AEN will be sent when a corrupted flash file system is found on the controller during boot-up. A further attempt will be made to repair the flash file system. When this event happens, the Battery Backup Unit is still able to backup the 3ware RAID controller, but the user should replace the battery. When this event happens, the Battery Backup Unit is still able to backup the 3ware RAID controller but the user should replace the battery pack.
