Copy the Software Update Files
DPOD software updates are available through IBM Fix Central. The download consists of two files:
The update file:
DPOD-fixpack-<version number>.sfsThe md5 checksum of the update file:
DPOD-fixpack-<version number>.md5
Verify the integrity of the downloaded update file by calculating its md5 checksum and comparing it to the downloaded md5 checksum file.
Create necessary directories:
mkdir -p /installs/update/fix/TODO /installs/update/fix/logs
Copy the downloaded files to the following directory on the DPOD server:
/installs/update/fix/TODO
Make Sure there is Enough Free Disk Space
Inspect the free space of each mount point. You may use the following command:
df -h
The following table lists the required available space:
Mount Point | Required Available Space |
|---|---|
/ | 100 MB |
/installs | 4 GB + internal configuration database size |
If there is not enough free space on the /installs mount point, you may free some from the following directories:
Directory | Description |
|---|---|
/installs/update/fix/TODO | Remove old DPOD update files (.sfs). |
/installs/backups | Move old DPOD backup directories to a different server. It is recommended not to delete the backups until you are absolutely sure you don’t need them anymore. |
/installs/APPL-setup | Remove the directories. |
Install the Software Update
Execute the following commands as root (using sudo is not supported):
cd /installs/update/fix/TODO MonTierUpdateInstaller.sh -u DPOD-fixpack-<version number>.sfs -s DPOD-fixpack-<version number>.md5 For example: MonTierUpdateInstaller.sh -u DPOD-fixpack-1_0_18_0.sfs -s DPOD-fixpack-1_0_18_0.md5
Do not interrupt the software update process after it has started.
Please review the upgrade log file if the console displays any error messages.
If SSH connection is lost during upgrade, the upgrade will still continue. Reconnect to the server and check the log files for the process status and outcome.
Manual Steps during the Software Update
Rerunning the Installer after an Operating System Update
Some versions upgrade the operating system (CentOS) when DPOD is installed in Appliance Mode.
In that case, the installer should be rerun manually after the OS upgrade is complete and the server is restarted.
Rerunning the Installer after an Installer Update
Some versions make changes to the installer files themselves. In that case, the following message will be displayed, and the installer should be rerun manually:
Found a new version of the software update installer. The software update installer was updated successfully. Important: Please run the software update installer again!
