This blog is part of my Scaling Out Search Series and describes the processes for adding a new admin component to a new search server:
Get Search Service Instance and Start on New Index Server$ssi = Get-SPEnterpriseSearchServiceInstance -Identity "<<new index server>>"
Start-SPEnterpriseSearchServiceInstance -Identity $ssi
Wait for Search Service Instance to come online
Get-SPEnterpriseSearchServiceInstance -Identity $ssi
(The full script contains a loop that waits for the service to come online)
Clone Active Search Topology$ssa = Get-SPEnterpriseSearchServiceApplication
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active
$clone = New-SPEnterpriseSearchTopology -SearchApplication $ssa -Clone –SearchTopology $active
Add New Admin ComponentNew-SPEnterpriseSearchAdminComponent -SearchTopology $clone -SearchServiceInstance $ssi
Activate the Cloned Search Topology
Set-SPEnterpriseSearchTopology -Identity $clone
Review new topology
Get-SPEnterpriseSearchTopology -Active -SearchApplication $ssa
Monitor Distribution of Index
Get-SPEnterpriseSearchStatus -SearchApplication $ssa
(The full script contains a loop that waits for the index component to be Active)
The new index component will be "Degraded" until the index is fully synced. Use the -text parameter to retrieve more detailed information.
My second search server was now complete!

Once all components are Active, reviewing the Search Application Topology in Central Admin shows the following:

How about if you don't have an existing Admin component to clone?
ReplyDeletethen you are adding the first one. you clone the search topology regardless.
