Manage pools, volume groups, and SSD Cache

You can manage pools, volume groups, and SSD Cache to change configuration settings, delete pools and volume groups from the storage array, view SSD Cache statistics, check volume redundancy in a pool or volume group, and consolidate free capacity for a volume group.

  • Change configuration settings for a pool
    You can edit the settings for a pool if you want to change its name, edit the capacity alerts settings, its modification priorities, or preservation capacity.
  • Change SSD Cache settings
    You can edit the name of the SSD Cache and view its status, maximum and current capacity, Drive Security and Data Assurance status, and its associated volumes and drives.
  • Change RAID level for a volume group
    You can change the RAID level for a volume group to accommodate the performance needs of the applications that are accessing the volume group. This operation changes a volume group's RAID level without impacting data I/O.
  • View SSD Cache statistics
    You can view statistics for the SSD Cache, such as reads, writes, cache hits, cache allocation percentage, and cache utilization percentage.
  • Check volume redundancy
    Under the guidance of technical support or as instructed by the Recovery Guru, you can check the redundancy on a volume in a pool or volume group to determine whether the data on that volume is consistent. Redundancy data is used to quickly reconstruct information on a replacement drive if one of the drives in the pool or volume group fails.
  • Delete pool or volume group
    You can delete a pool or volume group to create more unassigned capacity, which you can reconfigure to meet your application storage needs.
  • Consolidate free capacity for a volume group
    Use the Consolidate Free Capacity option to consolidate existing free extents on a selected volume group. By performing this action, you can create additional volumes from the maximum amount of free capacity in a volume group.
  • Export/Import volume groups
    Volume group migration lets you export a volume group so that you can import the volume group to a different storage array.
