Dell PowerFlex v3.6.x CLI Reference Guide
set_volume_rmcache_usage
Control the use of RMcache in the specified volume.
You can only configure one volume at a time. If you want to ensure that all I/Os for this volume are cached, the relevant Storage Pool should be configured to use RMcache, and the relevant SDSs should all have RMcache enabled.
NOTE:You can also enable
RMcache at the volume level during initial creation of the volume using the
--add_volume command.
Syntax
scli --set_volume_rmcache_usage (--volume_id <ID>| --volume_name <NAME>)(--use_rmcache | --dont_use_rmcache) [--i_am_sure]
Parameters
- --volume_id <ID>
- Volume ID
- --volume_name <NAME>
- Volume name
- --use_rmcache
- Use Read RAM Cache on the volume.
- --dont_use_rmcache
-
Do not use RMcache on the volume. This is the default setting.
- --i_am_sure
- Skip the safety questions for command execution. (For example: “This could damage the stored data. Are you sure?”)
Example
scli --set_volume_rmcache_usage --volume_name vol_10 --use_rmcache
