qospolicy modify

--id ID

Specifies which QoS policy to modify.

--policy-type VIEW|USER

Determines whether the QoS policy provisions performance for a view (VIEW) or for one or more users (USER).

--is-default

When specified, the policy is used as the default user QoS policy for all users under the tenant specified in --tenant-id.

Caution

Specifying this option resets the list of users assigned to this policy.

--tenant-id ID

If the QoS policy is to be used for one or more users  (--policy-type USER), specify the ID of the tenant whose users can be assigned this QoS policy.  

Tip

To assign users to a user QoS policy, run the qospolicy attach-user command.

--use-total-limits

If specified, enables you to set limits that cap the total amount of read, write and metadata operations (see --static-total-limits and --capacity-total-limits).

--use-separate-limits

Disables total QoS limits.

--limit-by BW_IOPS|BW|IOPS

Sets performance characteristic(s) by which to limit service:

--static-total-limits STATIC_TOTAL_LIMITS

Enables and sets static QoS limits that cap the total amount of read, write and metadata operations.

Specify STATIC_LIMITS as a comma-separated list of key=value pairs.

The following keys can be used, depending on the --limit-by setting:

For example: min_bw_mbps=1024,max_iops=2048

--static-limits STATIC_LIMITS

Enables and sets static QoS limits.

Tip

Minimum limits can only be set when --mode STATIC is specified.

Specify STATIC_LIMITS as a comma-separated list of key=value pairs.

The following keys can be used, depending on the --limit-by setting:

Note

The limits starting with min_ can be applied to user QoS policies only.

For example:

max_reads_bw_mbps=1024,max_writes_iops=2048

--mode STATIC|USED_CAPACITY| PROVISIONED_CAPACITY

Determines how capacity-based limits are set:

--capacity-total-limits CAPACITY_TOTAL_LIMITS

Enables and sets QoS limits per unit of used or provisioned logical capacity, depending on the provisioning mode (see --mode), that cap the total amount of read, write and metadata operations.

Specify CAPACITY_TOTAL LIMITS as a comma-separated list of key=value pairs, where the following keys can be used, depending on the --limit-by setting:

For example: max_bw_mbps_per_gb_capacity=1024,max_iops_per_gb_capacity=2048

--capacity-limits CAPACITY_LIMITS

Enables and sets QoS limits per unit of used or provisioned logical capacity, depending on the provisioning mode (see --mode).

Specify CAPACITY_LIMITS as a comma-separated list of key=value pairs, where the following keys can be used, depending on the --limit-by setting:

For example:

max_reads_bw_mbps_per_gb_capacity=1024,max_writes_iops_per_gb_capacity=2048

--is-gold

Sets a prioritization flag for the QoS policy so that the workloads have higher priority in contention for CPU and memory resources. This option applies to view QoS policies only. For more information, see Prioritizing Workloads.

--disable-gold

Removes the prioritization flag from the QoS policy.

--s3-connections-limit LIMIT

Sets the   maximum allowed number of S3 connection. QoS Overview

By default, no S3 connection limit is set. '0' means unlimited number of S3 connections is allowed.
