Question 1 of 7
⚙️
Is ILMT deployed on ALL servers running IBM PVU-based software?
IBM requires ILMT on every server with PVU-licensed products. Even one missing server can invalidate sub-capacity rights.
Yes — 100% coverage confirmed
Mostly — 95%+ but some gaps
Partially — deployed on major servers only
Not deployed or unsure of coverage
Question 2 of 7
📊
Are you generating and retaining ILMT reports as required?
IBM requires quarterly ILMT reports to be generated and retained for 2 years. Missing reports invalidate sub-capacity.
Yes — quarterly reports generated and retained
Reports generated but not quarterly or gaps exist
Reports generated sporadically
No reports generated or retained
Question 3 of 7
🖥️
What virtualisation technologies host IBM software?
IBM sub-capacity rules vary by hypervisor. VMware requires ILMT. PowerVM and z/VM have specific capping requirements.
Physical servers only
PowerVM or z/VM with proper capping
VMware with ILMT tracking
VMware without ILMT or mixed/unknown platforms
Question 4 of 7
📦
Do you run IBM software in containers (Docker, Kubernetes, OpenShift)?
Containerised IBM software has specific licensing rules. Without proper isolation, the entire cluster may be in scope.
No containerised IBM software
OpenShift with IBM Cloud Paks (properly licensed)
Containers on Kubernetes — licensing unclear
Containers in multiple environments — no licensing review
Question 5 of 7
🔄
Have your virtualisation environments changed since ILMT was deployed?
Adding hosts, clusters, or moving VMs can create ILMT coverage gaps that invalidate sub-capacity rights.
No changes — or ILMT updated to reflect all changes
Minor changes — ILMT mostly current
Significant changes — ILMT may not be current
Major infrastructure changes — ILMT not updated
Question 6 of 7
💰
What is the estimated cost difference between sub-capacity and full-capacity for your environment?
This is the financial risk of losing sub-capacity rights. The difference can be millions of dollars.
Under $500K difference
$500K-$2M difference
$2M-$10M difference
$10M+ or unknown
If unknown, assume worst case
Question 7 of 7
🛡️
Have you had your ILMT configuration independently validated?
ILMT misconfigurations are extremely common. Incorrect agent settings, missing servers, or wrong bundling can all invalidate sub-capacity.
Yes — independent validation completed
Internal review only
No — set up and not reviewed since
No — and ILMT was set up by IBM or a partner
IBM setups often miss edge cases
