What is controllerPreservedCache?
Indicates whether the controller currently holds preserved cache -- unflushed write-cache data retained after an unexpected virtual disk removal or failure, pending recovery: 1 Yes, 0 No, 99 Not available/Not applicable. A Yes here is urgent: it means there's cached data that hasn't made it to disk, and the admin must restore the missing virtual disk before that data can be flushed or is lost.
Examples
