Symptom: During a VMware Vmotion event, the client (ISE) is quiesced. This means all I/O is paused for some period of time. Sometimes when this happens, ISE fails to recover. This can result in the system freezing or worse, a kernel panic. We currently say this is supported with shared storage. We don't currently support VMware Snapshots because they behave in a similar way. Conditions: Performing a VMotion on an active ISE node, especially when under load.
