Yes |
WorkloadQueue object |
Resource pool objects |
Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
workload_queue_name |
Yes |
String |
Resource pool name The value must start with a lowercase letter and contain 3 to 28 characters, including only lowercase letters, numbers, and underscores (_). |
logical_cluster_name |
No |
String |
Name of a logical cluster In non-logical cluster mode, leave this parameter blank. In logical cluster mode, it is the logical cluster name. |
