Hello, I looked into the forum but could not find any idea. I need to send an email alert when a PHYSICAL disk fails (better still when a disk is close to failure, SMART reports this). I am not interested in logical or volume failures. I tried with disk activity but this is an event that frequenty goes to zero% under normal conditions. I also could not find a way to configure the alert if the low disk activity persists for long time (e.g. one hour). Thank you in advance for some suggestions. Thank you. Rob
