qospolicy modify

--id ID

Identifies the QoS policy to modify.

--attached-iam-roles <ROLES>

Attaches a user QoS policy to one or more IAM roles.

Specify <ROLES> as a comma-separated list of IAM role IDs, for example: 2,5,8.

--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.

--policy-type {VIEW|USER}

Determines whether the QoS policy provisions performance for views (VIEW) or users (USER).

--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.

--capacity-limits <LIMITS>

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

Specify <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

--capacity-total-limits <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 <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

--limit-by {BW_IOPS|BW|IOPS}

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

--mode <MODE>

Determines how capacity-based limits are set.

Specify <MODE> as one of the following:

--s3-connections-limit LIMIT

Sets the  maximum allowed number of S3 connections.

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

--static-limits <LIMITS>

Enables and sets static QoS limits.

Specify <LIMITS> as a comma-separated list of key=value pairs.

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

For example:

max_reads_bw_mbps=1024,max_writes_iops=2048

--static-total-limits <LIMITS>

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

Specify <LIMITS> as a comma-separated list of key=value pairs.

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

For example: max_iops=2048

--use-separate-limits

Disables total QoS limits, allowing you to apply separate QoS limits for read and/or write operations.

--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).

--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.

--disable-gold

Removes the prioritization flag from the QoS policy.
