Configured for single-cluster
Device Port SCSI address 7
Time: 16-APR-2007 16:00:14
Smart Error Eject Enabled
Host PORT_1:
Valid node name: HSJ3RA, valid CI node 3, 16 max nodes
System ID 42001003FFE4
Path A is ON
Path B is ON
MSCP allocation class 1
TMSCP allocation class 0
MAXIMUM_HOSTS = 4

Re: HSJ80 Controller Question

"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."

"SMART â Self-Monitoring Analysis and Reporting Technology"

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
