This integer holds the low-order 32 bits of a 64-bit counter of read requests not immediately serviced because the requested data was still in the process of loading into cache, paired with the high-order cpqDaLogDrvCacheVolAccelNoOfReadMissLoadingH value, and returns -1 if not applicable. An admin watches this to gauge how often application reads have to wait briefly for a cache load already in progress rather than being served instantly. For example, a high cpqDaLogDrvCacheVolAccelNoOfReadMissLoading count during a reporting job suggests concurrent requests are frequently hitting data that's mid-load into the accelerator.
