SCSI command summary

SCSI command summary

The following two tables summarize the SCSI commands supported by the subsystem. The first table summarizes them in alphabetical order by command name. The second table lists commands in numerical order of opcode value.

Notes:

A '·' in this column indicates that the command will fail if there is a LUN reservation in place by another initiator at the time the command is received.
In the Breadth of Operation field, Device refers to either a drive or JBOD enclosure controller (LCC.)
These commands will not return Reservation Conflict status but will silently do nothing.
