Chapter 5: ATTO FibreBridge SCSI Commands
This chapter describes the SCSI commands that are processed by the ATTO FibreBridge.
INQUIRY command
The INQUIRY command requests that information regarding parameters of the target and a component
logical unit is sent to the application client.
If an INQUIRY command is received from an initiator with a pending unit attention condition (i.e., before
the ATTO FibreBridge reports CHECK CONDITION status), the ATTO FibreBridge will perform the
INQUIRY command and will not clear the unit attention condition.
