We had an incident the other day where one of our Azure VMs suddenly became unresponsive. I couldn't do anything to troubleshoot it other than try to reboot. The reboot worked but the machine was still not reachable. At this point I tried a full shutdown. After this it wouldn't start back up and kept throwing this error:
Windows Azure is currently performing an operation with x-ms-requestid 7de542381adc1663b6900ded12912df4 on this deployment that requires exclusive access
After about 30 minutes the VM started up and I was able to remote in. However, the VM now has a different VIP than what it was originally given. Also, the Cloud Service containing the VM does not show a VIP at all. What could have caused this?
I fixed our issues by updating our DNS records to point to the new VIP, but I need to know how to prevent this in the future.
On a sidenote, what's up with Azure support? The pricing calculator states that web incidents are included with any subscription, but when I try to submit a case it won't move forward because I don't have a support plan?!
Thanks!
