17.2.3 Performing Live Migration of the Cluster on the Guest Domains

Creating /etc/opt/FJSVcluster/etc/clovmmigrate.conf (guest domain)
Create the /etc/opt/FJSVcluster/etc/clovmmigrate.conf file on all the nodes, and register the cluster configuration node and the destination server information beforehand.
Note
- Keep the clovmmigrate.conf file consistent for all cluster nodes.
- Take this procedure only once. It does not have to be taken for each Migration.
  However, if the configuration is changed after this procedure is taken, take the procedure described in "17.2.2 Changing Configuration after Setting Prerequisites."
```
primary_IP primary_weight primary_PPAR-ID XSCF-name1 XSCF-name2
                            :
```
- Create the clovmmigrate.conf file with system administrator authority and set the permission of the file to 600.
- Describe the information of a single node in one line.
- Use a space delimiter between each item.
primary_IP
The host name registered to the IP address or the /etc/inet/hosts file of the control domain
primary_weight
The SF node weight of the control domain
For the cluster configuration among the different physical partitions (only between guest domains), set 1.
primary_PPAR-ID
The identification ID of the physical partition (PPAR) of control domain.
For SPARC M10-1, M10-4, and M12-2, make sure to specify "0".
For SPARC M10-4S and M12-2S, specify an integer ranged from 0 to 15.
XSCF-name1
The IP address of XSCF-LAN#0 or the host name that is registered in the /etc/inet/hosts file.
Available IP addresses are IPv4 addresses.
For SPARC M10-4S and M12-2S, specify the XSCF takeover IP address.
XSCF-name2
The IP address of XSCF-LAN#1 or the host name that is registered in the /etc/inet/hosts file.
Available IP addresses are IPv4 addresses.
For SPARC M10-4S and M12-2S, specify the XSCF takeover IP address.
Example: When the environment is built with the two-node cluster between guest domains ("Figure 17.1 Cluster configuration example")
```
host1 4 0 XSCF#1-LAN#0 XSCF#1-LAN#1
host2 2 0 XSCF#2-LAN#0 XSCF#2-LAN#1
host3 1 1 XSCF#3-LAN#0 XSCF#3-LAN#1
```
Disabling the link between the node weight of the guest domain and the node weight of the control domain
Execute the following command on any guest domain.
```
# /etc/opt/FJSVcluster/bin/cldevparam -p WeightMode 0
```
Setting /etc/system (guest domain)
Add the following description to "/etc/system" on the target guest domain to which a cluster system is migrated with Migration. Then, reboot the system.
This step 3 is unnecessary in the environment where SRU9.5.1 or later of Solaris 11.1 is applied.
