Point
It is recommended that you back up the following resources before starting the upgrade.
By preparing a backup, in cases when an error occurs during the upgrade, it is possible to return the system to its state prior to the upgrade, simply by recovering (restoring) the system from the backup.
System (the primary node and the secondary node)
The shared disk for shared data of the AdvancedCopy Manager CCM
Login to the server on which to perform the tasks. Perform operations after logging in with root (superuser).
Ensure that there is enough available disk space (100 MB) on the server where the upgrade is performed on the secondary node.
In cases when upgrade installation is executed in a state where the capacity required for the upgrade is not available, the following message is displayed and the installation terminates in an error. Re-execute the upgrade after securing the capacity required for the installation.
Output Message (in cases when the directory of the destination of the installation is "/opt"):
ERROR:Disk /opt has an insufficient free space. Please execute it again after increasing the disk area.
Check that the CCM Server transactions are stopped on the secondary node.
If not stopped, stop the transaction of AdvancedCopy Manager Copy Control Module.
Refer to the relevant cluster software manuals for information on stopping it.
On the secondary node, recover the start and stop script of the CCM Server transaction.

Stop the CCM Server transaction on the primary node.
Refer to the relevant cluster software manuals for information on stopping it.
The shared disk for shared data of AdvancedCopy Manager Copy Control Module must be mounted.
On the primary node, recover the start and stop script of the CCM Server transaction.
