If your Identity Server hard drive fails, you must reinstall Identity Server (see Installing Identity Server) and leave Identity Server configuration intact in Administration Console. To preserve the existing keystores, perform the following steps before installing Identity Server on the new hard drive:
Stop the server.
In Administration Console, click Access Manager > Identity Servers. Select the server and click Stop. Allow a few seconds for the server to stop.
Select the server, then click Actions > Remove from Cluster.
Select the server, then click Actions > Delete.
Reinstall Identity Server. (See Section 3.0, Installing Identity Server.)
On the Identity Server page, select the server, then click Actions > Assign to Cluster.
Select the Identity Server cluster configuration, then click Assign.
Click OK.
