Haven't actually had a crash in a long time, but the last time my client had one that was basically the scenario. By the time I was getting instant messages and automated alerts / pages were going out to everyone, the system was already back up and had 100% application availability. It was something like a 10 minute outage total. The client wasn't happy, but it sure beats the heck out of "the old days" of initiating a stand alone dump manually and re-ipling after it completed. That's if an operator or even a sysprog could find the doc or knew how to do an SADUMP and do it correctly!
