Answer 1

Hi Roberto,

Hope you’re doing well.

Question1: Unable to use live migration.

1. Check the cluster live migration configuration and ensure that the virtual machines used for live migration are stored in CSV (Cluster Shared Volumes).
2. Please check the following configuration, right-click question machine, select “settings”, and check the “Processor -> Compatibility”:

Make sure this feature is checked.

3. Please open cmd as an administrator and then input the following command to check all machine patches:

wmic qfe >c:\hotfix.txt

Make sure all patches are up to date.

4. If none of the above steps work, please open PowerShell and input the following commands and provide us the screenshot:

Compare-VM -Name xxx -DestinationHost xxx

---

(Compare-VM -Name xxx -DestinationHost xxx).Incompatibilities | fl *

Question2:iSCSi connection with SAN go down.

When the issue occurs, are there any error messages? If so, please provide us the screenshots.

Hope my answer can help you!
