イベントの詳細

Event:scsi.cmd.checkCondition: Disk device 0b.00.10: Check Condition: CDB 0x9a:0000000044478778:0001:0050: Sense Data SCSI:aborted command - (0xb - 0x4b 0x5 0x0)(9). Message Name:scsi.cmd.checkCondition Sequence Number:21455748 Description:This message occurs when a check condition is received from a device. A check condition is the mechanism whereby a target device reports an informational condition or error status to the requesting host. Either the condition that generated this event is an error that occurred during execution of the command and was not cleared by retrying the request or an informational condition reporting status of the present operation or media state.

Event: scsi.path.excessiveErrors: Excessive errors encountered by adapter 0a on disk device 0b.00.10. Message Name:scsi.path.excessiveErrors Sequence Number:21455740 Description: This message occurs when excessive errors are encountered on this device within a short-enough time period to raise concern that there might be a faulty component between the storage initiator and device. You can use the option 'ra.path_switch.threshold' to control how sensitive Data ONTAP(R) is to device errors. Setting it to a higher value requires more errors to trigger this event.
