Dell PowerFlex Manager 4.6.x CLI Reference Guide
set_protected_maintenance_mode_policy
Set the protected maintenance mode I/O priority policy for a storage pool. This feature affects system performance, and only advanced users should modify it.
Syntax
scli --set_protected_maintenance_mode_policy (((--protection_domain_id <ID> | --protection_domain_name <NAME>) --storage_pool_name <NAME>) |--storage_pool_id <ID>) --policy <POLICY> (Options) [--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
- --policy <POLICY>
- Policy to use for protected maintenance mode I/O priority. Can be one of the following:
- no_limit
- Protected maintenance mode I/Os are not limited.
- limit_concurrent_io
- (Default) Limit the number of allowed concurrent protected maintenance mode I/Os to the value defined for concurrent_io_limit.
- favor_application_io
- Limit the number of allowed concurrent protected maintenance mode I/Os to the values defined for concurrent_io_limit and bandwidth_limit, regardless of user I/Os.
- Options
- Choose one or several:
- --concurrent_io_limit <LIMIT>
- The maximum number of concurrent protected maintenance mode I/Os per device. Default: 1.
- --bandwidth_limit <BANDWIDTH>
- The maximum bandwidth of protected maintenance mode I/Os, in KB/s, per device. The valid range is 1024-1048576. Default: 10,240. This property will take effect only if the policy is set to favor_application_io.
- --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_protected_maintenance_mode_policy --protection_domain_name pd1 --storage_pool_name sp1 --policy favor_application_io --bandwidth_limit 5120
