Why does flexcache volume become inaccessible when Origin volume is made offline
Applies to
- Flexcache
- ONTAP 9 and later
- CVO
Answer
- Origin volume cannot be made offline. It will affect Flexcache volume access
- When a FlexCache volume receives a read request of the hot data it contains, it can respond faster than the origin volume because the data does not need to travel as far to reach the client
- If a FlexCache volume receives a read request for infrequently read data (cold data), it retrieves the needed data from the origin volume and then stores the data before serving the client request
