Upgrade
DPOD software updates are available from time to time and include enhancements, security updates, component upgrade, bug fixes etc.
The following sections describe the process of upgrading an existing installation.
Cumulative Upgrade
Up to version 1.0.8.6, each DPOD fix pack file does not include previous fix packs. For example, in order to upgrade from 1.0.7.0 to 1.0.8.6:
- First upgrade to 1.0.8.0 with the 1.0.8.0 fix pack file.
- Then upgrade to 1.0.8.6 with the 1.0.8.6 fix pack file.
From version 1.0.8.6 and above, the latest fix pack in Fix Central includes all previous fix packs above 1.0.8.6. For example, in order to upgrade from 1.0.8.0 to 1.0.10.0:
- First upgrade to 1.0.8.6 with the 1.0.8.6 fix pack file.
- Then upgrade to 1.0.10.0 with the 1.0.10.0 fix pack file, which includes both 1.0.9.0 and 1.0.10.0.
Upgrading Cell Environment
To upgrade a Cell environment - first stop DPOD on the Cell Manager and on all Cell Members, then upgrade the Cell Members, and only after all Cell Members have been upgraded, upgrade the Cell Manager.
Obtain the Software Update
DPOD software updates are available through IBM Fix Central.
The download consists of two types of files:
- The update file: DPOD-fixpack-<version number>.sfs (for example: DPOD-fixpack-1_0_8_5.sfs)
- The md5 hash calculation of the update file: DPOD-fixpack-<version number>.md5 (for example: DPOD-fixpack-1_0_8_5.md5)
Ensure squashfs Support (only for Non Appliance Installation)
Make sure the update file can be mounted (squashfs support) using the following command:
lsmod | grep squash expected output : squashfs
Copy the Software Update to DPOD Server
Copy the update files to the following directory on DPOD server:
/installs/update/fix/TODO
If the directory is missing for some reason, please create it:
mkdir -p /installs/update/fix/TODO
Make Sure there is Enough Disk Space
Root ("/") Mount Point Free Space
The root ("/") mount point requires at least 100MB free space.
Installs ("/installs") Mount Point Free Space
The "/installs" mount point free space can be displayed using the following command:
df -h /installs Output example: Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_inst-lv_inst 7.0G 5.5G 1.6G 79% /installs
During the software update installation, the internal configuration database is being backed-up. The backup requires additional available disk space on the "/installs" mount point.
To calculate the needed available disk space for the internal configuration database backup please use the following command (in this example DB size is 43MB):
du -ksh /app/derby/ Output example: 43M /app/derby/
See the following table for required available disk space on "/installs" for the software update:
Version | Needed Available Disk Space |
---|---|
1.0.3.X | 700MB + DB SIZE |
1.0.4.X | 700MB + DB SIZE |
1.0.5.X | 2500MB + DB SIZE |
1.0.6.X | 700MB + DB SIZE |
1.0.7.X | 3000MB + DB SIZE |
1.0.8.X | 2000MB + DB SIZE |
1.0.9.X | 3000MB + DB SIZE |
1.0.10.X | 4000MB + DB SIZE |
If there is not enough free disk space on the "/installs" mount point you may free some by deleting files from the following directories:
Directory | Description |
---|---|
/installs/update/fix/TODO | Remove old DPOD update files (.sfs) |
/installs/update/fix/backups | Remove old DPOD backup directories |
/installs/APPL-setup | Remove DPOD installation file |
Install the Software Update
A technical issue prevents upgrading DPOD installations that were installed using version 1.0.2.0 ISO file. Before upgrading an 1.0.2.0 ISO-based DPOD installation to a newer version, please run the following command from a console / ssh session: cd /installs && rm -rf dev-tools
Run the following command from the location you downloaded the update files to:
MonTierUpdateInstaller.sh -u DPOD-update-<version number>.sfs -s DPOD-update-<version number>.md5 For example: MonTierUpdateInstaller.sh -u DPOD-update-1_3_0.sfs -s DPOD-update-1_3_0.md5
You may encounter the following message:
INFO file MonTierUpdateInstaller.sh was updated successfully. INFO important !!! Please run MonTierUpdateInstaller.sh again.
This message means that the MonTierUpdateInstaller.sh was updated and you should rerun the command.
After running the command again you will be prompted to confirm the software update process. press "Y" to confirm or "N" to abort.
Do Not interrupt the software update process after it has begun
Please review the upgrade log file if the console displays any error messages.
