What are the rules used by Upgrade Advisor in Active IQ Digital Advisor
Applies to
- ONTAP systems
- Active IQ Digital Advisor - Upgrade Advisor
Description
The new Upgrade Advisor in Active IQ Digital Advisor was rewritten in a new, more agile platform and aligns to the best practice of using Automated Non-Disruptive Upgrade (ANDU).
- Plans are now created by numeric Functional Step rules, that are context/configuration sensitive as well as Warning and Upgrade Blocker (Error) rules that use the same rules infrastructure as the Wellness card risks, but are specifically focused on the upgrade workflow.
- Upgrade Advisor logic depends on "WEEKLY_LOG" or "USER_TRIGGERED (ALL:" AutoSupport message.
- AutoSupport messages are scanned within 10 minutes of receipt by Active IQ Digital Advisor.
- If you have already resolved an issue, but it is not reflected in the last "WEEKLY_LOG" or "USER_TRIGGERED (ALL:" AutoSupport message then you may see warnings about issues you have already addressed.
- Some upgrade/validation functions may cause automatic USER_TRIGGERED Maintenance (MAINT) AutoSupport messages or sometimes a TEST AutoSupport is sent manually.
- If this is the most recent message, it may cause missing/partial Upgrade Advisor checks due to incomplete AutoSupport content.
- If this happens, Upgrade Advisor will provide an "Upgrade Blocker" error explaining the problem.
- For a full scan, submit a new AutoSupport and wait 10 minutes.
- ANDU incorporates a number of upgrade of pre-checks and post-checks.
- Upgrade advisor will duplicate some, but not all of these checks.
- Upgrade advisor will not provide generic guidance such as: "run
sysstat
command to assess performance", or "check for active jobs" because these checks are already part of the cluster image validation prechecks. - This helps you avoid having to run extra, unnecessary commands that manually duplicate work done by existing pre-validation scripts.
- Obsolete checks such as "Verifying that deduplicated volumes and aggregates contain sufficient free space" have been removed from Upgrade Advisor.
- For example the task above was made obsolete in ONTAP 9.1.
