To monitor the storage pool free space: 1. Click Group. 2. Click Storage Pools to open the Storage Pool summary window. Check the free pool space value in the Storage Pools panel. Dell recommends that free pool space not fall below the following level (whichever is smaller): • 5 percent of the total pool space • 100GB multiplied by the number of pool members You can increase free pool space by moving volumes from the low-space pool to a different pool. You can expand pool capacity by moving a member to the pool. You can sort the table by clicking the heading of a column; the table is sorted by Volume Template by default.
