Azure Migrate Physical Server - enable replication

Question

• Error ID 320016
• Error Message Disk details are not available for replication disks '{5544188b-50cd-46bd-955d-d598a3f8a153},{77b47667-49ce-439c-a1f2-02a78defb928}' for the machine 'WIN-NB3RPHN470A'.
• Possible causes The disks are not reported correctly for machine 'WIN-NB3RPHN470A'.
• Recommendation Retry the operation after some time. If the issue persists, contact support. I want to migrate a physical server that has iscsi storage attached to the server disk, but when enable replication fails, I get the error information as above, even when I exclude the iscsi disk. I still get the error

Hi ,

 

Thanks for reaching out to Microsoft Q&A.

This is a known azure migrate limitation with physical servers that have iSCSI LUNs attached. Even if you exclude the iSCSI disks during replication setup, the Azure Migrate appliance still discovers them at the OS level and fails to reliably collect disk metadata, which triggers Error ID 320016. In short, Azure Migrate for physical servers does not fully support iSCSI-attached storage, because it expects locally attached disks (basic disks with stable identifiers). To proceed, you must either completely disconnect the iSCSI targets from the server before enabling replication, or migrate the server using a backup based approach (for example, Azure Backup or third-party tools). Retrying will not fix this; it is not a transient issue.
