New Post: Unable to retrieve topology component health states.

If you are assigning search roles/components to different servers, then you need to make sure that you provision the enterprise search to all of those servers (see bold below).

For example

<EnterpriseSearchService Provision="__LGLVSPP01-APP03,LGLVSPP01-IDX02,LGLVSPP01-APP03__" ContactEmail="" ConnectionTimeout="60" AcknowledgementTimeout="60" ProxyType="Default" IgnoreSSLWarnings="false" InternetIdentity="Mozilla/4.0 (compatible; MSIE 4.01; Windows NT; MS Search 6.0 Robot)" CustomIndexLocation="c:\SearchIndex" PerformanceLevel="PartlyReduced" ShareName="SearchIndex">
   
<EnterpriseSearchServiceApplication Name="Search Service Application"
    FailoverDatabaseServer=""
    Partitioned="false"
    Partitions="1"
    SearchServiceApplicationType="Regular"
    ContentAccessAccount="CRAWL-ACCOUNT-NAME"
    ContentAccessAccountPassword="CRAWL-ACCOUNT-PASSWORD">
    <Database>Removed for brevity</Database>
    <ApplicationPool Name="SharePoint Search Application Pool" />

    <CrawlComponent>
    <Server Name="LGLVSPP01-APP03" />
    </CrawlComponent>
    <QueryComponent>
    <Server Name="LGLVSPP01-IDX02" />
    </QueryComponent>
    <!-- You should specify all the servers you listed in QueryComponent in the SearchQueryAndSiteSettingsServers node below as well -->
    <SearchQueryAndSiteSettingsServers>
    <Server Name="LGLVSPP01-APP03" />
    <Server Name="LGLVSPP01-IDX02" />
    </SearchQueryAndSiteSettingsServers>
    <!-- You can only run the AdminComponent on one server per Search Service App in a SP2010 farm, so only list one server here unless you are installing SharePoint 2013 and need multiple Admin components. -->
    <AdminComponent>
    <Server Name="LGLVSPP01-APP03" />
    <ApplicationPool Name="SharePoint Search Application Pool" />
    </AdminComponent>
    <!-- IndexComponent is only required for SP2013 -->
    <IndexComponent>
    <Server Name="LGLVSPP01-IDX02" />
    </IndexComponent>
    <!-- ContentProcessingComponent is only required for SP2013 -->
    <ContentProcessingComponent>
    <Server Name="LGLVSPP01-APP03" />
    </ContentProcessingComponent>
    <!-- AnalyticsProcessingComponent is only required for SP2013 -->
    <AnalyticsProcessingComponent>
    <Server Name="LGLVSPP01-APP03" />
    </AnalyticsProcessingComponent>
    <Proxy Name="Search Service Application" Partitioned="false">
    <ProxyGroup Name="Default" />
    </Proxy>
    <!-- SearchCenterUrl is for SharePoint 2013 only and is used to set the global search center URL per http://autospinstaller.codeplex.com/workitem/18944. 
     The url you enter MUST end with /Pages or a localized variant of it (i.e. /Seiten in German, /Paginas in Dutch) in order for it to work correctly from MySites. 
     Do not add a trailing slash. i.e.: https://search.zomers.eu/Pages when your Search Center site collection is deployed as a host named site collection to https://search.zomers.eu -->
    <SearchCenterUrl>https://internal.company.com/SearchCenter/Pages</SearchCenterUrl>
</EnterpriseSearchServiceApplication>
