Nodus5 server offline and the currently resident VMs being orphaned.
Per the ticket, only MicroStrategy users. The actual impact was broad in that 30+ virtual machines (VM) went off-line including the VM running SiteScope. However, the only ticket actual opened had to do with the MicroStrategy web service not being accessible.
The root cause for the outage was a hardware/driver failure in the Nodus5 server.
Reboot Nodus5 and move orphaned VMs to a different physical host. The MicroStrategy issue was resolved by starting the associated proxy server.
Working with hardware and software vendors to determine root cause of Nodus5 failure – update firmware and drivers, and potentially replace hardware components.
