This integer holds the low-order 32 bits of a 64-bit counter of read cache hits for this cache volume, combined with the high-order cpqDaLogDrvCacheVolAccelNoOfReadHitsH value, and returns -1 if not determinable. An admin trends this counter upward as confirmation that reads are increasingly being served from the fast cache volume rather than primary storage. For example, a rapidly climbing cpqDaLogDrvCacheVolAccelNoOfReadHits after enabling caching on a reporting server confirms the accelerator is effectively absorbing repeated read queries.
