HyperV 2012 Upgrade

Hi,



I have 2 X DELL R640 Hosts running Windows Hyperv 2012R2

They both share a ISCSI Storage (DELL 5020 SAN)



HOST B has had all VM's evicted and been upgraded (Fresh Install) to Server 2016.  All roles installed. Network configured.  iSCSI Setup.



Current status is: the disks show as RAW - when bringing online they came up as RAW and with a drive letter.



HyperV is not able to see the disk.



According to the steps, i should now be selecting Copy Cluster Roles, but i am afraid that if i did this and storage not accessible from the new Host, what will the impact be.


Or as part of the Copy does the storage information get copied across and is the SAN made availbale to the new Host ?



some urgent assistance required, please.



Thanks

Hi,

Thanks for posting on our forum!

Based on your description, you do need to solve your "RAW" issue firstly. Good for you! In this place you can use general troubleshooting to deal with the "RAW" issue:
https://www.easeus.com/resource/raw-external-hard-drive-recovery.htm

Please note: Information posted in the given link is hosted by a third party. Microsoft does not guarantee the accuracy and effectiveness of information.

In addition, there are a few points I need to check in order to have a panoramic view of your production environment:
1) You evicted and updated your VMs from Failover cluster Manager>> Node >> VM >> evict, or on the basis of VM roles?
2) Where did you find your disk become "RAW"? from Disk Management?
3) What do you mean "HyperV is not able to see the disk"?

Finally, i notice that you need urgent service. In this case, I would suggest you contact Microsoft Customer Support and Services where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue. For instance, if it turns out that your issue needs log analysis and real-time remote troubleshooting by our senior supporters, you still need to open a case at that moment. In addition, if the issue has been proved as system flaw, the consulting fee would be refund. You may find phone number for your region accordingly from the link below.
