HSJ80 Controller Question

[MJ26]

I would like an explanation to what SMART ERROR EJECT ENABLED or (DISABLED) means? I have not seen this setting before. Here is the current setup for the controller:

Any answers would be greatly appriciated. Thank you.

"SMART Error Drive Eject â In prior versions of ACS, SMART error notifications received from a device were treated as soft (recovered) errors. The notification was passed to the host and operations continued. ACS now provides a CLI switch (smart error eject state) that offers an alternative to this behavior.

With the new switch enabled, drives in a normalized and redundant set that report a SMART error are removed from that set. SMART errors reported by drives in a non-redundant or non-normal set continue to be treated as recovered errors. If the switch is disabled, all SMART errors are treated as recovered errors."

I've posted up some notes around SMART resulting from on some recent papers... HLRL: Disk Storage and Failure Rates, at http://64.223.189.234/node/93
