B.3.1 Upgrading from PRIMECLUSTER Enterprise Edition 4.6A00

Boot all the cluster management servers in single user mode.
Check the default target.
Note
- The default target before upgrading ([multi-user.target] in the following example) varies depending on the system.
- Put down the default target before upgrading as you can restore the system to the state prior to upgrading later.
```
# systemctl get-default <Return>
multi-user.target
```
The default target changes in single-user mode.
```
# systemctl set-default rescue.target <Return>
```
Start the system again in single-user mode.
```
# shutdown -r now <Return>
```
When update the basic software from existing environment, Updating basic software, see the following document Operating Update manual.
Proceed the following steps on each cluster management server.
1. Create a backup directory.
```
# mkdir /<mydir> <Return>
```
2. Back up the PRIMECLUSTER operating environment.
```
# cp -p /opt/FJSVwvbs/etc/webview.cnf /<mydir> <Return>
# cp -p /opt/FJSVwvbs/etc/.policy /<mydir> <Return>
# cp -p /opt/FJSVwvbs/etc/wvlocal.cnf /<mydir> <Return>
```
  Check if the Plugin.html file has not been changed.
  Open the /opt/FJSVwvbs/etc/Plugin.html file using a text editor then check the default value( 60 ) is set for the following entry:
```
<PARAM NAME = Initial_wait VALUE ="60">
```
  If it is different from the default value, take a note of the value.
  This value will be used to restore it later.
3. Insert the DVD and mount the DVD device.
```
# mount -t iso9660 -r /dev/<device file name> <DVD-ROM mount point> <Return>
```
```
<DVDROM_DIR> will be used as the mount point.
```
4. Execute the following script then delete part of the PRIMECLUSTER package.
```
# cd <DVDROM_DIR>/Tool <Return>
# ./upgrade_uninstall <Return>
Are you sure to remove a part of PRIMECLUSTER from your system (y or n) ? y <Return>
:
:
The uninstallation finished successfully.
```
5. Execute the following cluster_install script, and install the package or override it.
```
# cd <DVDROM_DIR>/Tool <Return>
# ./cluster_install -e EE-M <Return>
:
:
The installation finished successfully.
```
  Note
  - The following message might be output:
    # ./cluster_install -x xx <Return> INFO: no package to update
    This message indicates that the newer version of all the packages is installed, so it is not necessary to upgrade.
  - While executing the cluster_install script, the following message might be output
    # ./cluster_install -x xx <Return> Installing package <XXXXXXXXXXX> ... skipped.
    This message indicates that the same version of all the packages is installed, so it is not necessary to upgrade.
6. Eject the DVD.
```
# cd / <Return>
# umount <DVDROM_DIR> <Return>
# eject cdrom <Return>
```
7. Restore the PRIMECLUSTER operating environment that was backed up at step 2.
```
# cp -p /<mydir>/webview.cnf /opt/FJSVwvbs/etc/webview.cnf <Return>
# cp -p /<mydir>/.policy /opt/FJSVwvbs/etc/.policy <Return>
# cp -p /<mydir>/wvlocal.cnf /opt/FJSVwvbs/etc/wvlocal.cnf <Return>
```
  If you find the Plugin.html file has been changed at step 2, restore the value.
  There is no need to do this step if it has not been changed.
  Edit the /opt/FJSVwvbs/etc/Plugin.html file using a text editor then write the value noted at step 2 back to the file (in the example "xx" ):
```
(Example)
   [Before Modification]
     <PARAM NAME = Initial_wait VALUE ="60">
   [After Modification] 
     <PARAM NAME = Initial_wait VALUE ="xx">
```
8. Set the java_home environment variable of Web-Based Admin View.
```
# /etc/opt/FJSVwvbs/etc/bin/wvSetparam java_home /opt/FJSVwvbs/jre <Return>
```
After completing step 3 on all the cluster management servers, reboot all the cluster management servers.
The default target changes in multi-user mode.
```
# systemctl set-default multi-user.target <Return>
```
Start the system again.
```
# shutdown -r now <Return>
```
