@KK1969 Thank you for contacting us!
I understand that you are trying to enable Azure VM replication across subscription and blocked with disk failure errors.
Replication of Azure VMs from one subscription another is supported only when source and target subscription are part of same Azure Active Directory Tenant.
Also, check if your subscription has permissions to create resources in the target region.
Refer to - https://learn.microsoft.com/en-us/azure/site-recovery/azure-to-azure-support-matrix
Is it related to "temp drive D:/"and should be excluded while initiating the replication? If yes, post failover how will the "temp drive D:/" get created at Target Azure VM? Please clarify.
Temp disks are excluded by default. See the exclusion list - https://learn.microsoft.com/en-us/azure/site-recovery/exclude-disks-replication#exclude-limitations
A temporary drive is created by Azure compute platform for temporary storage. This is created for any VM created on Azure (VM creation experience below) not specific to ASR.
Suggestions to try:
- Reboot source VM and then try replication
- Disable replication and then re-enable replication
- Disable replication, reboot source VM and re=enable replication
If problem persist, contact Azure technical support team by raising a support request.
