Change Controlling PDomain-SPP for Host (Failover)

Language:

Before You Begin

Not all SPARC M series servers support PDomain-SPP failover. Therefore, if the Oracle ILOM properties described in this procedure do not appear in the CLI and web interface, the PDomain-SPP host failover feature is not supported. For further details about failover operations supported on a server, refer to the administration guide provided for the server.
The Admin (a) role is required to change the controlling PDomain-SPP for host.
Changing the controlling PDomain-SPP might cause an interruption in communication between the Host PDomain-SPP and Oracle ILOM. If this occurs, any active Oracle ILOM Remote System Console Plus sessions on the PDomain-SPP will automatically be disconnected.

To change the controlling PDomain-SPP that is currently responsible for managing Host system activity, follow these steps

Identify the active SPP for the PDomain by performing one of the following:
- Web: Click System Management > Domains page and view the SP Name column in the Host Configuration table.
  - or -
- CLI: Type: show /Servers/PDomains/PDomain_n/host
  View the sp_name = property to identify the active PDomain-SPP.
To change the controlling PDomain SPP for host, perform one of the following:
- Web: Click System Management > Domains page, then click the More details... link for instructions.
  - or -
- CLI: Type: set /Servers/PDomains/PDomain_n/host initiate_sp_failover=<true|force>
  Where true gracefully negotiates the PDomain-SPP assignment, where force forcibly changes the PDomain-SPP assignment. If a prompt appears to confirm that you want to continue the failover operation. Type y to continue, otherwise type n.
