Manage volumes

You can manage volumes to increase reported capacity, initialize volumes, redistribute volumes, and delete volumes. You can also change a volume's settings, ownership, cache settings, and media scan settings.

  • Increase capacity of a volume
    You can increase the reported capacity (the capacity reported to hosts) of a volume by using the free capacity that is available in the pool or volume group.
  • Change settings for a volume
    You can change a volume's settings such as its name, host assignment, segment size, modification priority, caching, and so on.
  • Initialize volumes
    A volume is automatically initialized when it is first created. However, the Recovery Guru might advise that you manually initialize a volume to recover from certain failure conditions. Use this option only under the guidance of technical support. You can select one or more volumes to initialize.
  • Redistribute volumes
    You redistribute volumes to move volumes back to their preferred controller owners. Typically, multipath drivers move volumes from their preferred controller owner when a problem occurs along the data path between the host and storage array.
  • Change controller ownership of a volume
    You can change the preferred controller ownership of a volume, so that I/O for host applications is directed through the new path.
  • Change cache settings for a volume
    You can change read cache and write cache settings to impact the overall I/O performance of a volume.
  • Change media scan settings for a volume
    A media scan is a background operation that scans all data and redundancy information in the volume. Use this option to enable or disable the media scan settings for one or more volumes, or to change the scan duration.
  • Delete volume
    Typically, you delete volumes if the volumes were created with the wrong parameters or capacity, no longer meet storage configuration needs, or are snapshot images that are no longer needed for backup or application testing. Deleting a volume increases the free capacity in the pool or volume group. You can select one or more volumes to delete.
