It is possible to start the IO domain before the guest domain after server switchover, by creating a definition file that specifies the IO domain.
When not using IO domains, it is not necessary to create a definition file.
Point
The startup order of a control domain, IO domain, and guest domain is not guaranteed by the OVM for SPARC specifications.
Therefore, if this definition file is not created, the guest domain will be started before the IO domain and there is a chance that starting of the IO domain will fail.

Describe the definition file as below:
Enter the admin IP address of the control domain of the switchover source server for the ADMIN_IP key value and insert a line break.
Type the IO domain names of the server in the desired startup order, separating with line breaks.
IO domains will start in the order specified in the definition file.
Until the following is stated, the IO domains are regarded as the IO domains of the server specified for the ADMIN_IP key:
Another ADMIN_IP key
End of the file
Example
ADMIN_IP=192.168.10.123 |
Create a definition file when necessary, before server switchover.
It is not necessary to restart the manager.
