DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following incidents:

Patch ID: 7.4.2.200

* 4008502 (Tracking ID: 4008744)

SYMPTOM:
Rolling upgrade using response file fails if one or more operating system packages are missing on the cluster nodes.

DESCRIPTION:
When rolling upgrade is performed using response file, the installer script checks for the missing operating system packages and installs them. After installing the missing packages on the cluster nodes, the installer script fails and exit. The following error message is logged:
CPI ERROR V-9-40-1153 Response file error, no configuration for rolling upgrade phase 1.
This issue occurs because the installer script fails to check the sub-cluster numbers in the response file.

RESOLUTION:
The installer script is enhanced to continue with the rolling upgrade after installing the missing OS packages on the cluster nodes.

* 4010025 (Tracking ID: 4010024)

SYMPTOM:
CPI assumes that the third digit in an InfoScale 7.4.2 version indicates a patch version, and not a GA version. Therefore, it upgrades the packages from the patch only and does not upgrade the base packages.

DESCRIPTION:
To compare product versions and to set the type of installation, CPI compares the currently installed version with the target version to be installed. However, instead of comparing all the digits in a version, it incorrectly compares only the first two digits. In this case, CPI compares 7.4 with 7.4.2.xxx, and finds that the first 2 digits match exactly. Therefore, it assumes that the base version is already installed and then installs the patch packages only.

RESOLUTION:
This hotfix updates the CPI to recognize InfoScale 7.4.2 as a base version and 7.4.2.xxx (for example) as a patch version. After you apply this patch, CPI can properly upgrade the base packages first, and then proceed to upgrade the packages that are in the patch.
