WHY CANT I UPGRADE MY VCPU QUOTA

Question

Whenever I try to upgrade my quota they says "enable to upgrade your quota" I've already troubleshooted so many times , how should i upgrade my quota now?

Answer 1

Hey Shahenshah,

it sounds like you’re running into a “unable to upgrade your quota” error when you try to bump up your vCPU limits. Here are the most common reasons and what you can do next:

1. Check your subscription type
   1. Free Trial subscriptions can’t get quota increases.
   2. If you’re on a Free Trial, upgrade to Pay-As-You-Go first: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits#how-to-manage-limits
2. Verify you’re targeting the right quotas
   • vCPU quotas are enforced two ways: a) Total Regional vCPUs b) Per-VM-family vCPUs (for example, D-series, E-series, M-series)
   • If either limit is hit, Azure will block additional cores.
3. Request the quota increase via the Azure portal a) Portal → Subscriptions → select your subscription b) Settings → Usage + quotas c) Filter by Service Name = Microsoft.Compute and by Location d) Locate the quota you need (Total regional vCPUs or the specific VM-family) e) Click the pencil icon (Request increase), enter your desired new limit, and Save
4. Or open a Support Request a) Portal → Help + support → Create a support request b) Issue type = Service and subscription limits (quotas) c) Quota type = Compute – VM (cores-vCPUs) d) Fill in Region, VM-family, New limit, and justification → Submit
5. If you’re still blocked:
   • Double-check there aren’t any pending quota requests or denials in Help + support → My support requests
   • Consider a different region or VM family if your primary choice isn’t available
   • Ensure you’re not trying to resize a VM to >64 vCPUs on an OS that doesn’t support it (Linux/Windows images have OS caps)

Follow-Up Questions

1. What subscription type are you using (Free Trial, Pay-As-You-Go, EA)?
2. Which region(s) and VM-family quotas are you trying to increase?
3. What are your current usage vs. limit values (you can grab these under Usage + quotas)?
4. Did you already submit a quota request? If so, what’s the status in “My support requests”?
5. Are you trying to resize an existing VM beyond 64 vCPUs on an unsupported guest OS?

Answer 2

The message indicates that the quota increase request is being rejected, not that the feature is unavailable. When a quota can’t be upgraded directly, it usually falls into one of these cases:

1. The quota is non‑adjustable in the portal (hard limit or special resource type).
2. The requested value exceeds what can be auto‑approved.
3. The specific quota type or region requires a support request instead of the inline “New Quota Request” flow.

Use the supported paths below to move forward.

1. Check if the quota is adjustable
2. Sign in to the Azure portal and search for Quotas.
3. On Overview, select Compute.
4. On My quotas, find the quota that is failing to upgrade and check the Adjustable column:
   • If Yes → it should be upgradable directly (see step 2).
   • If No → it is a non‑adjustable quota and must be increased via a support request (see step 3).
5. Retry the increase correctly for adjustable quotas
6. In Quotas → Compute → My quotas, select the specific VM-family vCPU quota or Total Regional vCPUs that needs to be increased.
7. Select New Quota Request.
8. Choose either:
   • Enter a new limit and enter a numeric value, or
   • Adjust the usage % and move the slider to increase the limit.
9. Select Submit.
10. If the request is denied, a link appears to open a support request. Use that link so a support engineer can review and override where possible.

If the request is approved, Azure automatically increases the related regional vCPU quota for that region.

3. Open a support request for non‑adjustable or failing quotas

If the quota shows as non‑adjustable, or the portal keeps saying it is unable to upgrade:

1. Go to Quotas → Compute.
2. Locate the quota and select the support icon next to it.
3. In the New support request form:
   • Confirm subscription and region.
   • For Quota type, choose the appropriate option (for example, Virtual Machines, Virtual Machine Scale Sets, or “Other Requests” depending on what is shown).
4. On Additional details, specify:
   • The exact quota name (for example, Standard Dv3 Family vCPUs in eastus).
   • The new limit requested.
5. Complete and submit the request.

For some quotas (for example, certain VM or VMSS quotas), this is the only supported way to increase them. A support engineer will then review and either increase the quota or explain any subscription‑level limits.

4. If the portal quota blade does not work

If the Quotas page fails to load or behaves incorrectly, use the support‑request path above (via the support icon or the generic “Create a support request” entry point) and describe that the Quotas blade is not functioning. Support can both fix the portal issue and manually adjust quotas.

5. When quota errors block AKS or other services

If the quota issue appears while creating or scaling services like AKS, the underlying fix is still to increase the relevant VM-family vCPU quota or regional vCPU quota in the region used by that service, using the same quota‑increase methods described above.
