Maintenance evidence
Power 6 TPM Coverage and Risk Checker
Test whether a third-party maintenance agreement is a real Power 6 operating bridge or a contract that leaves the important failure modes uncovered.
What does the maintenance agreement actually cover?
A provider name is not coverage. The useful evidence is the exact machine, named parts, response commitment, exclusions, escalation process, and the recovery plan behind the contract.
How the result is produced:
Contract specificity, parts evidence, restore testing, and the intended hold period determine whether maintenance is a usable bridge or whether migration work should take priority.
Limit:
This checker does not verify a provider's inventory or service performance. Written coverage and references must be confirmed directly.
The failure lesson that matters
Legacy maintenance fails when everyone assumes somebody else owns the missing piece. The useful record names the failed component, the source of the replacement, the actual response time, the recovery step, and what changed afterward.
