6.7.2 Upgrading on Clustered Systems

Point

It is recommended that you back up the system before starting the upgrade. If a failure occurs during the upgrade, you cannot restore the environment to the pre-installation status (rollback).

When returning back to the state before installation of the upgrade, recover (restore) the system from the backup.

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.
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, perform a backup of the operating environment of the previous version of the AdvancedCopy Manager Copy Control Module.
Note that the capacity required for performing this backup is 100 MB.
1. Login to the server on which to perform the tasks. Perform operations after logging in with root (superuser).
2. Insert the DVD "ETERNUS SF SC/ACM Mediapack for Solaris (V16.9 or higher) Manager Program (2/2)" or "ETERNUS SF SC/ACM/Express Mediapack for Linux 64bit (V16.9 or higher) Manager Program (2/2)" of this version into the DVD drive.
3. Mount the DVD media.
  - Example for Solaris environments
```
# mount -F hsfs -o ro /dev/dsk/c0t4d0s0 dvdMountPoint
```
    The device name of the DVD drive may differ depending on the device. In this example, the device name of the DVD drive is mounted as "/dev/dsk/c0t4d0s0".
  - Example for Linux environments
```
# mount -t iso9660 -r /dev/cdrom dvdMountPoint
```
    The device name of the DVD drive may differ depending on the device. In this example, the device name of the DVD drive is mounted as "/dev/cdrom".
4. Execute the following command to perform a backup of the previous version.
  For backupDir, specify the directory in which to store the backup data with an absolute path.
```
# dvdMountPoint/Manager_unix/vuptools/esfccmpreinst_cluster.sh backupDir -primary
```
  When the backup fails, after confirming the output error message and removing the cause of the failure, re-execute the command.
  Point
  - Spaces and the characters " / ` * ? \ $ [ ] , % ! { } are not supported for directory name.
  - The number of characters in a directory name must be up to 220.
5. Change to a directory other than the DVD media.
  Example:
```
# cd
```
6. Unmount the DVD media.
```
# umount dvdMountPoint
```
7. Eject the DVD media.
Checking for available disk space
Ensure that there is enough available disk space on the server where the upgrade is performed.
The required disk space for the upgrade is calculated as the "Required Disk Space for New Version" minus the "Required Disk Space for Previous Version".
