> Disable and Remove Host operation disables the primary storage capacity.
> Steps to replicate:
> Base Condition: There exists a host and storage pool with same id
> Steps:
> 1. Find a host and storage pool having same id
> 2. Disable the host
> 3. verify that the CPU(1) and MEMORY(0) capacity in op_host_capacity for
> above host is disabled
> 4. verify that the STORAGE(3) capacity in op_host_capacity for storage pool
> with id same as above host is also disabled
> RCA:
> 'host_id' column in 'op_host_capacity' table used for storing both storage
> pool id (for STORAGE capacity) and host id (MEMORY and CPU). While removing a
> HOST we also disable the capacity associated with host.
> Ideally while disabling capacity we should only disable MEMORY and CPU
> capacity, but we are not doing so.
> Code Path:
> ResourceManagerImpl.doDeleteHost() ->
> ResourceManagerImpl.resourceStateTransitTo() ->
> CapacityDaoImpl.updateCapacityState(null, null, null, host.getId(),
> capacityState.toString())
> updateCapacityState is updating disabling all entries which matches the
> host_id. This will also disable a entry having storage pool id same as that
> of host id.
