This integer holds the low-order 32 bits of a 64-bit counter of write cache hits for this cache volume, paired with the high-order cpqDaLogDrvCacheVolAccelNoOfWriteHitsH value, and returns -1 if not determinable. An admin trends this counter to confirm writes are increasingly being absorbed by the fast cache volume rather than going straight to primary storage. For example, a steadily rising cpqDaLogDrvCacheVolAccelNoOfWriteHits after enabling write caching on a busy volume confirms the accelerator is effectively buffering write traffic.
