PRESERVING MANAGEMENT SERVICES WITH SELF-CONTAINED METADATA THROUGH THE DISASTER RECOVERY LIFE CYCLE

摘要

During normal operation, at a first site, of a disaster recovery management unit, at least one customer workload machine, at least one management service machine, and metadata for the at least one management service machine are replicated to a remote disaster recovery site. After a disaster at the first site, a replicated version of the at least one customer workload machine and a replicated version of the at least one management service machine are brought up at the remote disaster recovery site. A replicated version of the metadata for the at least one management service machine is reconfigured by executing, on the replicated version of the at least one management service machine, a failover script, to obtain reconfigured replicated metadata for the replicated version of the at least one management service machine. When the first site comes back up, failback is carried out, essentially in the reverse order.

1. A method comprising:
during normal operation, at a first site, of a disaster recovery management unit comprising at least one customer workload machine and at least one management service machine, replicating to a remote disaster recovery site said at least one customer workload machine, said at least one management service machine, and metadata for said at least one management service machine; and after a disaster at said first site:
bringing up, at said remote disaster recovery site, a replicated version of said at least one customer workload machine;bringing up, at said remote disaster recovery site, a replicated version of said at least one management service machine; andreconfiguring a replicated version of said metadata for said at least one management service machine by executing on said replicated version of said at least one management service machine a failover script, to obtain reconfigured replicated metadata for said replicated version of said at least one management service machine, so that said replicated version of said at least one management service machine can provide said management service to said replicated version of said at least one customer workload machine in said remote disaster recovery site.
