Use sp_cluster logical, "drop" to drop one or more resources from a logical cluster. A base instance or a failover instance must be offline before it can be dropped.
You can drop:
Base instances – for example, to drop instance “ase2” from “SalesLC”, enter:
sp_cluster logical, "drop", SalesLC, instance, ase2
Failover instances – for example, to drop failover instances “ase3” and “ase4” from “SalesLC”, enter:
sp_cluster logical, "drop", SalesLC, failover, "ase3;ase4"
