I saw a recent question about Logical Domain recovery: If you have a control domain installed on a server and the server goes down with a hardware fault, what options do you have for recovering the logical domains from that control domain?
The answer is that you have options depending on how your environment is configured:
If you want to add the failed control back in, before you rediscover it and put it back in the server pool, you should log in and make sure that the guest OS isn't running, to avoid split brain issues.
Take a look at the Recover Logical Domains from a Failed Server how-to for more information.
