This integer holds the low-order 32 bits of a 64-bit counter of the total number of write cache misses for this cache volume (summing do-load, loading, and skip categories), paired with the high-order cpqDaLogDrvCacheVolAccelNoOfWriteMissTotalH value, and returns -1 if not applicable. An admin uses this aggregate figure alongside write hits to compute an overall write cache effectiveness ratio for the volume. For example, a rising cpqDaLogDrvCacheVolAccelNoOfWriteMissTotal relative to write hits after adding new write-heavy applications suggests the write cache volume may need to be resized.
