Requirements for Shared Storage Pools
Limitations for Shared Storage Pools
NOTE: The system reserves a small amount of the reported Shared Storage Pool capacity to record consistency records. The remainder of the Shared Storage Pool capacity is available for storage of virtual client partition user data. Shared Storage Pool threshold monitoring should be used to notify the VIOS Administrator when free capacity falls below an acceptable level. The default threshold monitoring is set to alert when the free capacity in the pool is lower than 75% of the total capacity. As a precautionary measure, the VIOS Administrator should not allow the free capacity to drop below 5% of the total capacity or I/O operations on the virtual client partition may fail. In the event that no storage capacity is available, physical volumes must to be added to the pool or data deleted from the pool to create additional free capacity.
