Recovering LDoms From a Failed Server

Guest Author

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 have the control domain in a server pool, and you have enabled automatic recovery on the LDom, you have the option of watching as the LDom is automatically brought back up on another control domain in the server pool.
  • If the control domain is in a server pool but you didn't enable automatic recovery, you can still manually migrate the guest by deleting the control domain asset. The guests will then be put in the Shutdown Guests list for the server pool, and you can bring it up on another control domain.
  • 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.

      Hi,

      I have a question regarding how HA works with Ops Center: Is it necessary to have Ops Center 12c up and running in order to Automatic Fsilover to work? What happens if Ops Center is down?

      Thanks in advance,
