   where

   • RESOURCE_POOL_ID: indicates the ID of a resource pool, which uniquely identifies a resource pool.

   • TENANT_ID: indicates the ID of the tenant to which the resource pool belongs, which uniquely identifies a tenant. The ID of the sys tenant is 1. For instructions on viewing detailed information about the current tenant, see View tenant and resource information.

     If the value of TENANT_ID is NULL, the resource pool is not bound to any tenant. You can allocate the resource pool to a tenant. For instructions on allocating a resource pool to a tenant, see Allocate a resource pool to a tenant.

   • UNIT_COUNT: indicates the number of resource units in the resource pool.

   • UNIT_CONFIG_ID: indicates the ID of a resource unit config (namely, a resource unit configuration) in the resource pool, which uniquely identifies a resource unit config.

     For instructions on viewing resource unit configs, see View resource unit configurations.

   • ZONE_LIST: indicates which zones are using the resources in the resource pool.
