HP xw6600 Workstation - Configuring SAS RAID Devices

Supported configurations

The following RAID configurations are supported on the HP xw6600 Workstation.
note:
This section does not apply to configuring SAS RAID in the Linux environment. For Linux SAS RAID, including supported configurations, refer to Installing and Configuring SAS Hardware RAID on HP Linux Workstations at http://www.hp.com/support/xw6600_manuals.
  • Up to four internal SAS hard disk drives
  • SAS to SATA data and power converter
  • LSI MegaRAID Storage Manager (MSM) for Windows
The following RAID configurations are supported on the HP xw6600 Workstation:
  • RAID 0 – Striped disk array
    • Two drive minimum
    • Improved I/O performance
    • No fault tolerance
  • RAID 1 — Mirrored disk array
    • Two drives
    • 100% redundancy
    • Can recover from single drive failure
    • Improved read performance
  • RAID 1E
    • Three drives minimum
    • Can be an odd number of drives
    • Can always recover from a single drive failure and, in some cases, can recover from two drive failures

SAS RAID 0 configuration

Follow the steps below to configure an Integrated Striped (IS) volume with the BIOS-based configuration utility. The configuration procedure assumes that the system already has the required disk and disk controllers.
  1. On the Main menu screen of the BIOS-based configuration utility, use the arrow keys to select an adapter.
  2. Press Enter to go to the Adapter Properties screen.
  3. On the Adapter Properties screen, use the arrow keys to select RAID Properties.
  4. Press Enter to go to the RAID Properties screen.
  5. In the RAID Properties screen, use the arrow keys to select the first disk for the IS volume. Then use the arrow keys to move to the Array Disk column for this disk, and press the SPACE, +, or - key to select Yes as the value for this column. If partitions are defined on the selected disk, a message appears warning you that data on the disk will be lost when the striped volume is created. Press the M key to migrate, or the D key to delete the data on the drive.
  6. Repeat the previous step to select up to three more disks for the striped volume.
  7. Press the C key to create the array once all drives have been chosen, then press Esc and select Save.

SAS RAID 1 configuration

Follow the steps below to configure an Integrated Mirroring (IM) volume with the BIOS-based configuration utility. The configuration procedure assumes that the system already has the required disk and disk controllers.
  1. On the Main menu screen of the BIOS-based configuration utility, use the arrow keys to select an adapter.
  2. Press Enter to go to the Adapter Properties screen.
  3. On the Adapter Properties screen use the arrow keys to select RAID Properties.
  4. Press Enter to go to the RAID Properties screen. .
  5. Chose one of the following options:
    To configure a two-disk mirrored volume with an optional hot spare disk:
    • In the RAID Properties screen, use the arrow keys to select the primary disk for the IM volume (the disk with the data you want to mirror.)
    • Use the arrow keys to move to the Array Disk column for this disk and use the SPACE key to select Yes as the value. If partitions are defined on the selected disk, a message appears warning you that data on the disk will be lost when the striped volume is created. Press the M key to migrate, or the D key to delete the data on the drive.
    • When the Keep Data/Erase Disk message appears, press F3 to keep the data currently on this disk. The value in the Array Disk column changes to Primary.
    • Use the arrow keys to select the secondary (mirrored) disk for the IM volume. Select Yes as the value for the Array Disk column.
      If partitions are defined on this disk, a message warns you that data on the disk will be lost when the mirrored volume is created. Press Delete to confirm erasing data from the disk, or press any other key to deselect the disk. Continue with Step 6.

SAS RAID 1E configuration

Follow the steps below to configure an Integrated Mirroring Extended (IME) volume with the BIOS-based configuration utility. The configuration procedure assumes that the system already has the required disk and disk controllers.
  1. On the Main menu screen of the BIOS-based configuration utility, use the arrow keys to select an adapter.
  2. Press Enter to go to the Adapter Properties screen.
  3. On the Adapter Properties screen use the arrow keys to select RAID Properties on the screen.
  4. Press Enter to go to the RAID Properties screen. Continue with Step 5 to configure a two-disk mirrored volume. Go to Step 6 to configure a mirrored volume with three to six disks.
  5. To configure a mirrored volume with three to six disks, or three to five disks with an optional hot spare disk:
    • In the RAID Properties screen, use the arrow keys to select the first disk for the IME volume.
    • Use the arrow keys to move to the Array Disk column for this disk, and use the + and - keys to select Yes as the value.
    • When the Keep Data/Erase Disk message appears, press Delete to erase the disk.
    • Use the arrow keys to select the next disk for the IME volume. Select Yes as the value for the Array Disk column.
      If partitions are defined on this disk, a message warns you that data on the disk will be lost when the mirrored volume is created. Press Delete to confirm erasing data from the disk, or press any other key to deselect the disk.
    • Repeat the previous steps to select up to four more disks for the IME volume. If you want to configure a hot spare disk for the volume, you can only select up to three more disks.
  6. (Optional) Use the arrow keys to select a hot spare disk for the IME volume. Select Yes as the value for the Hot Spare column.
  7. When you have selected all disks for the IME volume, press Esc and select Save changes, then exit this menu. If you do not want to create the IME volume, select Discard changes, then exit this menu.
    The IME volume exists as soon as you save the changes. The RAID Properties screen now displays the IME volume properties and status.
