15.4 Changing the Setting in the Single-User Mode

To build a cluster system, change the setting in the guest domain after migrating by P2V. Use the following procedure to change the setting.

Although it is not mentioned in the procedure, in general, editor commands such as vi(1) are used for editing files.

Start the guest domain in the single-user mode.
```
{0} ok boot -s
```
Remove a shared class forcibly.
Delete a class definition. If there are multiple classes, execute the command to all the classes.
```
# cd /etc/opt/FJSVsdx/sysdb.d
# rm class01
# rm class02
```
Delete the following lines from the class.db file.
```
...
class01     <- Delete this line
class02     <- Delete this line
...
```
When using the shared classes, delete the class definitions on all nodes in the class scope.
Start inhibition of RMS and SF.
1. Check the current configuration name of RMS.
```
# /etc/opt/FJSVwvucw/bin/wgcnfclient -g config-name config
```
  The output character string in the above is the currently-used RMS configuration name. If no character string is output, its RMS configuration name is "config".
2. Start inhibition and delete status of RMS.
  Execute the following command on all nodes.
```
# hvsetenv HV_RCSTART 0
# hvsetenv HV_RCSTART
0    <- Make sure "0" is output
# rm /opt/SMAW/SMAWRrms/.status_info
```
3. Start inhibition of SF.
  Execute the following command on all nodes.
```
# rm /etc/opt/SMAW/SMAWsf/rcsd.cfg
# ls /etc/opt/SMAW/SMAWsf/rcsd.cfg
/etc/opt/SMAW/SMAWsf/rcsd.cfg: No such file or directory
#
```
Set the NIC on the guest domain.
Change the NIC configuration file name due to the NIC name changes.
Create the network setting file (/etc/hostname.interface file or /etc/hostname6.interface file) of OS for the primary interface among NICs used in GLS to set the IP address or host name.
For details, see "3.2.2 Network Configuration" in "PRIMECLUSTER Global Link Services Configuration and Administration Guide 4.3: Redundant Line Control Function."
Delete network configuration files for NICs before migration if these files are left.
