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:

1. The update file: DPOD-fixpack-<version number>.sfs (for example: DPOD-fixpack-1_0_8_5.sfs)
2. 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:

If there is not enough free disk space on the "/installs" mount point you may free some by deleting files from the following directories:

Install the Software Update

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.

Please review the upgrade log file if the console displays any error messages.
