Parameters
Parameter |
Comments |
|---|---|
Set the threshold for triggering capacity usage alerts. Alerts thresholds are calculated from each Storage Pool capacity after deducting the defined amount of spare capacity. |
|
Threshold of the non-spare capacity of the Storage Pool that will trigger a critical-priority alert, expressed as a percentage. |
|
Threshold of the non-spare capacity of the Storage Pool that will trigger a high-priority alert, expressed as a percentage. This value must be lower than the critical_threshold. |
|
Enable/Disable fragmentation of a specific storage pool. Choices:
|
|
Enable/Disable rebalance on a specific storage pool. Choices:
|
|
Enable/Disable rebuild of a specific storage pool. Choices:
|

|
|
Set rebuild/rebalance parallelism limit of a storage pool. |
|
The password of the PowerFlex host. |
|
Enable/Disable persistent checksum of a specific storage pool. |
|
Bandwidth limit in KB/s for the checksum building process. Valid range is 1024 to 10240. Default: |

|
The I/O priority policy for protected maintenance mode.
If application I/Os are in progress, should also limit the bandwidth of protected maintenance mode migration I/Os to the limit defined for the bw_limit_per_device. Choices:
|
|
The id of the protection domain. During creation of a pool, either protection domain name or id must be mentioned. Mutually exclusive with protection_domain_name. |
|
The name of the protection domain. During creation of a pool, either protection domain name or id must be mentioned. Mutually exclusive with protection_domain_id. |
|
Set the rebalance I/O priority policy for a Storage Pool. |
|
The maximum bandwidth of rebalance I/Os, in KB/s, per device. Valid range is 1024 to 1048576. |
|
The maximum number of concurrent rebalance I/Os per device. Valid range is 1 to 20. |
|
Policy to use for rebalance I/O priority.
Choices:
|
|
Set replication journal capacity of a storage pool. |
|
Set RM cache write handling mode of a storage pool. Passthrough Writes skip the cache and are stored in storage only. Cached Writes are stored in both cache and storage (the default). Caching is only performed for IOs whose size is a multiple of 4k bytes. Choices:
|
|
Set the spare percentage of a specific storage pool. |
|
State of the storage pool. Choices:
|
|
The id of the storage pool. It is auto generated, hence should not be provided during creation of a storage pool. Mutually exclusive with storage_pool_name. |
|
The name of the storage pool. If more than one storage pool is found with the same name then protection domain id/name is required to perform the task. Mutually exclusive with storage_pool_id. |
|
New name for the storage pool can be provided. This parameter is used for renaming the storage pool. |
|
Time after which connection will get terminated. It is to be mentioned in seconds. Default: |
|
Enable/Disable RFcache on a specific storage pool. Choices:
|
|
Enable/Disable RMcache on a specific storage pool. Choices:
|
|
The username of the PowerFlex host. |
|
Boolean variable to specify whether or not to validate SSL certificate.
Choices:
|
|
Set the I/O priority policy for V-Tree migration for a specific Storage Pool. |
|
The maximum bandwidth of V-Tree migration I/Os, in KB per second, per device. Valid range is 1024 to 25600. |
|
The maximum number of concurrent V-Tree migration I/Os per device. Valid range is 1 to 20 |
|
The I/O priority policy for protected maintenance mode.
If application I/Os are in progress, should also limit the bandwidth of V-Tree migration I/Os to the limit defined for the bw_limit_per_device. Choices:
|
