Parameters

---

balancermember_active (array)

Provide a list of active balancemembers to be added to the catalog. Takes the same key names provided via $balancermember. If specified, it acts like a filter that removes all $balancermember not listed here.

Using this parameter you can deactivate balance members without needing to manipulate $balancemember. This enables you to use a global list for $balancemember and decide specificly which members are available. Also you can use $balancermember_active to easily disable members temporarily only.

If not specified (the default), $balancemember will not be modified.

• Default: undef

Limitations
