Creating a parity group

You can create parity groups for a set of physical drives that configure RAID in a storage system. A logical storage area extracted from a parity group is used as an LDEV (basic volume) that is used for allocation to hosts.

  1. In the Objects window, select the storage system where the parity group is to be added.

  2. On the Parity Groups tab, click the Create Parity Group icon.

  3. Specify the following:

    • Parity Group: Specify a number for the new parity group. For example, if the desired parity group number is 1 - 4, enter a 1 in the box on the left, and a 4 in the box on the right.
    • Drive Type: Select the type of drive from the pull-down list.
    • RAID Level: Select the RAID level from the list.
  4. Click Submit.
