Symptoms

The OS Rollup version is unknown.

Cause

While the proactive_check.pl script does report the OS Security Rollup version, there are certain situations (such as node additions or replacements) where it becomes necessary to check the version of the Security Rollup.

This process can also be used to check the version of the OS Security Rollup installed on an Avamar proxy.

Resolution

Every installation of the OS Security Rollup creates a package-survey-<OS_platform>-post_errata_installation-<date_stamp>.xml file in the /usr/local/avamar/var directory.

Therefore, the following command is used to check the installed version of the OS Security Rollup:
  
awk -F'"' '/<package-survey/ {print $2}' /usr/local/avamar/var/package-survey-*post_errata* |sort|tail -1

Sample output:
  
admin@avamar:~/>: awk -F'"' '/<package-survey/ {print $2}' /usr/local/avamar/var/package-survey-*post_errata* |sort|tail -1
2018-R4-v5
 
The version of the OS Security Rollup lets us know how recent the version is.
In our example, 2018-R4-v5 means that: 
  • The OS Security Rollup installed was released in 2018
  • It was the fourth Rollup released in that year
  • It is the fifth version of that specific Rollup
The numbers are in descending order of importance, so the most recent release is the release with the highest year, then the highest release ("R") number, and then the highest version ("v") number for that release.
