You can change the cache mode of the external volume in the Edit External Volumes window.
If the system cannot communicate with external volumes, the Inflow Control setting specifies whether the write operation to cache is limited (Enable) or continued (Disable). Disable is set by default. You can change the setting in the Edit External Volumes window. If you are using a Thin Image pool, all external volumes in the same pool must use the same Cache Mode setting.
- You must have the Storage Administrator (Provisioning) role.
- Before changing the cache mode of the external volume, review each item listed in the following table.
Item to Review | Description |
---|---|
Cache mode and pool volumes | When a volume is registered to a pool as a pool volume, the cache mode setting should be the same among all the pool volumes in the pool. |
Cache mode and remote command devices | When the volume is a remote command device, you cannot change the cache mode from Disable to Enable. |
