RAID-5

A RAID-5 volume spreads across two or more disks, and contains parity information. You have the option of placing a file system on the new volume.

Layout:

Choose RAID-5 for the volume layout.

In the Number of Columns field, specify the number of columns (disks) across which the volume should be striped. A RAID-5 volume requires at least three disks (or four disks if logging is enabled).

To specify a stripe unit size other than the default, enter the stripe unit size in the Stripe Unit Size field. To specify a size unit, attach an s (sectors), k (kilobytes), m (megabytes), or g (gigabytes) to the size.

Layout:

Choose Concatenated, Striped, Concatenated Pro, or Striped Pro for the volume layout.

For a striped or striped pro volume, provide the following information:


Mirror Info:

Select Mirrored. In the Total Number of Mirrors field, enter the total number of mirrors for the volume.

Resizing a Dynamic Volume

The Resize Volume procedure changes the size of a volume. If users require more space on a volume, you can use this procedure to increase the size of the volume. If a volume contains unused space that you need to use elsewhere, you can use this procedure to shrink the volume. If the volume contains a file system, this procedure also resizes the file system.

 
   To resize a volume

  1. Select the volume to be resized.
  2. Choose Actions > Resize Volumes.
  3. Complete the Resize Volume wizard as follows:
