Your system reports an alert when there is an issue or a potential issue that requires user attention. The Lenovo Storage V7000 helps resolve these problems through the Recommended actions only option from the Events panel.
Complete the recommended actions as quickly as possible after the problem is reported. Your system is designed to be resilient to most single hardware failures. However, if you operate for any period of time with a hardware failure, the possibility increases that a second hardware failure can result in some volume data that is unavailable.
If there are a number of unfixed alerts, fixing any one alert might become more difficult because of the effects of the other alerts.
