Understood, but planning for every possible disaster could be an infinite chore.
As I understand it, a memory chip failed. What underlying problems that caused weren't explained, but it did prompt them to failover their SAN (at some level) and that process started throwing errors. One would assume that 2.4 Billion Dollars a year to Northrop Grumman would include failover testing of such a major system, but we don't have that information. Were past DR tests successful? Had something changed between this failure and the last test to cause the failure? Did the hardware issue with the primary system somehow affect failover capabilities? It'd be nice to have those details but we'll probably never know. - Sean On Fri, Aug 27, 2010 at 10:37 AM, Jonathan Link <[email protected]>wrote: > Invariably, disasters can be planned for.
