Dell PowerFlex Manager 4.6.x CLI Reference Guide
set_rmcache_usage
Control the use of read RAM cache in the specified Storage Pool.
When using read RAM cache, you must also enable caching in each SDS in the storage pool using the enable_sds_rmcache command. Caching only begins once devices have been added to the SDSs.
NOTE:You can configure
read RAM cache for a storage pool and then disable caching on one or more SDSs individually.
Syntax
scli --set_rmcache_usage (((--protection_domain_id <ID> | --protection_domain_name <NAME>) --storage_pool_name <NAME>) |--storage_pool_id <ID>) (--use_rmcache | --dont_use_rmcache) [--i_am_sure]
Parameters
- --protection_domain_id <ID>
- Protection domain ID
- --protection_domain_name <NAME>
- Protection domain name
- --storage_pool_name <NAME>
- Storage pool name
- --storage_pool_id <ID>
- Storage pool ID
- --use_rmcache
-
Use read RAM cache in the storage pool.
- --dont_use_rmcache
- Do not use read RAM cache in the storage pool (the default).
- --i_am_sure
- Skip the safety questions for command execution. (For example: “This could damage the stored data. Are you sure?”)
NOTE:If you use the
storage_pool_id parameter in the command, you do not need to also specify the protection domain ID or name, and the storage pool name.
Example
scli --set_rmcache_usage --protection_domain_name pd10 --storage_pool_name spflash --use_rmcache
