When this timer expires, the SCSI layer will quiesce the host bus adapter (HBA) and wait for all outstanding commands to either time out or complete. Afterwards, the SCSI layer will activate the driver's error handler.When the error handler is triggered, it attempts the following operations in order (until one successfully executes):Abort the co.. 더보기 scsi_id examples on RHEL6 scsi_id examples in RHEL6,SL6,CentOS6 scsi_id is a tool to retrieve and generate a unique SCSI identifier, it's being widly used lots of system admin tools, primarily used by udev.
