- Rick click on the "computer" icon on the desktop or the computer item in the Start Menu.
- Select Manage.
- Expand Storage.
- Click on Disk Management.
- In the bottom center pane you'll see Disk 0, Disk 1, etc.
- On the left column under the Disk number you'll see the word Basic or Dynamic.
RAID ("Redundant Array of Inexpensive Disks" or "Redundant Array of Independent Disks") is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
The first place to look is in the Device Manager on the system: Right-click on "My Computer" and select "Manage." When the "Computer Manager" comes up, select "Device Manager>" Within the Device Manager is a section for "SCSI and RAID Controllers," as can be seen in the graphic below.
RAID 0 (also known as a stripe set or striped volume) splits ("stripes") data evenly across two or more disks, without parity information, redundancy, or fault tolerance. Once the stripe size is defined during the creation of a RAID 0 array, it needs to be maintained at all times.
To check RAID type from the command line:
- Go to System Settings.
- Click CLI Console.
- Type the command diagnose system raid status and press Enter.
- The following information is shown in the output: Mega RAID - this output shows that the device uses hardware RAID.
RAID 1 is a mirrored pair of disk drives. With RAID 5 – assuming again that you buy five disks – four-fifths of the capacity you buy is usable because the data is shared across four of the drives while one of the disks in the array acts as a parity disk that knows where all that data is located.
RAID is a Redundant Array of Inexpensive disks, but nowadays it is called Redundant Array of Independent drives. Raid is just a collection of disks in a pool to become a logical volume. Understanding RAID Setups in Linux. Raid contains groups or sets or Arrays.
Whether hardware or software, RAID is available in different schemes, or RAID levels. The most commonly levels are RAID 0, 1, 5, 6, and 10. RAID 0, 1, and 5 work on both HDD and SSD media. (RAID levels 4 and 6 also work on both media, but are rarely seen in practice.)
RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. It requires a minimum of four disks and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved.
lsblk lists information about all available or the specified block devices. The lsblk command reads the sysfs filesystem and udev db to gather information. The command prints all block devices (except RAM disks) in a tree- like format by default. Use lsblk --help to get a list of all available columns.
How do I check the RAID rebuild status?
- Log into the Platform Web interface as a user with Admin privileges to the Storage Groups page.
- A rebuilding storage group will show as an orange color.
- Select the "Properties" menu.
- The rebuild status will display as a small line in the bottom right listed as "Status" (See attached image)
Configuring the RAID
- Once you have completed your partitioning in the main "Partition Disks" page select "Configure Software RAID"
- Select "Yes"
- Select "Create new MD drive"
- Select RAID type: RAID 0, RAID 1, RAID 5 or RAID 6.
- Number of devices.
- Number of spare devices.
- select which partitions to use..
Mdadm - Configure Software Raid in Linux
- Change the partition type to RAID type. You need to use fdisk command to change the partition type of the participating disks.
- Creating the RAID Group. Now, we need to add these 3 disks into the RAID group.
- Format the RAID set md0.
- Configuring mdadm.
- Mount the RAID set.
Try the following commands for SCSI and hardware RAID based devices:
- sdparm Command – fetch SCSI / SATA device information.
- scsi_id Command – queries a SCSI device via the SCSI INQUIRY vital product data (VPD).
- Use smartctl To Check Disk Behind Adaptec RAID Controllers.
- Use smartctl Check Hard Disk Behind 3Ware RAID Card.
MegaCLI supports MS Windows, FreeBSD, Solaris and all major Linux distributions.
Install and Set Up MegaCLI
- Step 1: Verify Your Hardware RAID Controller. To use MegaCLI, you need a MegaRAID SAS controller.
- Step 2: Download MegaCLI.
- Step 3: Extract the MegaCLI Package.
- Step 4: Install MegaCLI.
- Step 5: Create an Alias.
RAID mode allows several hard disk drives to function as one storage area (the array) to provide either data redundancy (backup security) or faster performance (striped reading/writing data from or to the disk drives). note: HP recommends setting the SATA Controller Mode BEFORE installing the operating system.
Selecting the Best RAID Level
| RAID Level | Redundancy | Disk Drive Usage |
|---|
| RAID 1 | Yes | 50% |
| RAID 1E | Yes | 50% |
| RAID 10 | Yes | 50% |
| RAID 5 | Yes | 67 - 94% |
But AHCI is considerably faster than IDE, which is an older niche technology for outdated computer systems. AHCI do not compete with RAID, which provides redundancy and data protection on SATA drives using AHCI interconnects. RAID improves redundancy and data protection on clusters of HDD/SSD drives.
RAIDs can give you faster performance, more resiliency in case of a single drive failure, or the ability to build very large storage chunks out of not-very-large drives.
AHCI stands for Advance Host Controller Interface. It is a newer technology to provide advanced features to the Serial ATA standard. If you do not feel comfortable installing AHCI drivers, you may use what is referring to as SATA IDE Compatibility Mode which can be triggered in the motherboard BIOS.
AHCI is an operation mode in the SATA environment. You can enable the AHCI mode in BIOS settings before the installation. RAID is an advanced data storage technology that can enable you to use multiple hard drives for performance enhancement in different configurations.
RAID 0 and RAID 1 are two types of configurations or levels that can be set up with an array of independent disks. RAID 0 offers striping, which translates to better performance, but no-fault tolerance or data redundancy. RAID 1, on the other hand, offers mirroring, so the same data is available in two disks.
Look for the More Storage Settings heading and select Manage Storage Spaces. In the new window, select the “Create a new pool and storage space” option (Click Yes if prompted to approve changes to your system) Select the drives you want to pool and click Create pool. Together these drives will make up your RAID 5 array.
To Set the System BIOS and Configure Your Disks for Intel SATA or RAID
- Power on the system.
- Press the F2 key at the Sun logo screen to enter the BIOS Setup menu.
- In the BIOS Utility dialog, select Advanced -> IDE Configuration.
- In the IDE Configuration menu, select Configure SATA as and press Enter.
ACU is now available as an embedded utility, starting with HP ProLiant Gen8 servers. To access ACU, use one of the following methods: If an optional controller is not installed, press F10 during boot. If an optional controller is installed, when the system recognizes the controller during POST, press F5.
Disable the RAID feature from the system BIOS.Once located, scroll down the list options using the directional arrows on the computer keyboard and highlight the RAID configuration menu option. Select "disable" and press the enter key on your keyboard. Then press the "esc" key to return to the main menu. Exit the BIOS.
How to use Disk Sanitizer or Secure Erase
- Turn on or restart the computer.
- While the display is blank, press the F10 key repeatedly to enter the BIOS settings menu.
- Select Security.
- Select Hard Drive Utilities or Hard Drive Tools.
- Select Secure Erase or Disk Sanitizer to open the tool.
