Overview

This chapter helps you determine if a system was upgraded successfully.

What Happened During the Upgrade

A record of what the installation program did during an upgrade can be important to determine if the upgrade was a success. The output of the upgrade is saved in the following file:

• If upgrade fails - /a/var/sadm/install_data/upgrade_log
• If upgrade completes and system reboots - /var/sadm/install_data/upgrade_log

Cleaning Up the System After an Upgrade

During an upgrade, the Solaris installation program merges local software modifications of the existing system with the new software; however, in some cases, it is not possible. The following file provides a list of the unpreserved local modifications during the upgrade that may need to be fixed:

• If upgrade fails --/a/var/sadm/install_data/upgrade_cleanup
• If upgrade completes and system reboots - /var/sadm/install_data/upgrade_cleanup

Table 10-1 provides the entry descriptions of the unpreserved local modifications that may be found in the upgrade_cleanup file.

Table 10-1 upgrade_cleanup

Entry	Explanation	Recommended Action
file1: existing file renamed to file2	file1 was on the system at the time of the upgrade. It had been modified since its original installation, so upgrade renamed file1 to file2 and saved the new file as file1.	Determine whether the modifications made to file2 should be made to the new version of the file, file1.
file1: existing file preserved, the new version was installed as file2	file1 has been preserved, and upgrade installed the new version of the file as file2.	Determine whether the differences in the new version of file2 should be incorporated into the preserved version of file1.
file: had been deleted and has now been restored	file had been deleted from the system since its original installation, and the upgrade installed the new version of file.	Determine whether file should be deleted.
file: file type was changed from type1 to type2	file has changed types since its original installation, from type1 to type2. For example, you may have changed an actual file to be a symbolic link. The upgrade changed file back to its original type, type1.	Determine whether file should be changed back to type2.
file: target of symbolic link was changed from target1 to target2	Since the original installation, file was changed to be a symbolic link to target2 instead of target1. The upgrade changed file to point to its original target1.	Determine whether file should be changed to point to target2.
file1: target of hard link was changed from file2	When originally installed, file1 was a hard link to file2. At the time of the upgrade, file1 was no longer a hard link to file2.Upgrade restores the original hard link.	Determine whether file1 should be changed to what it was before the upgrade.
