Document Type and Number:
Japanese Patent JPH01166136
Kind Code:
A
Abstract:
PURPOSE:To prevent the congestion of troubles from occurring by preparing a command execution result as a status, discriminating whether the status is a trouble or not and executing the instruction to abandon on a command when it is in a fault. CONSTITUTION:When command executing parts 14-1-14-N are normal, commands 12-1-12-N issued from a host processor 1 are once stored in a common command queue 3 and they are respectively executed by the command executing parts 14-1-14-N. The command execution result is prepared as statuses 13-1-13-N by status preparing parts 15-1-15-N. Here, when the status 13-1 is in the fault, the instruction to abandon the command is outputted from a status discriminating part 11-1 to a command discriminating part 10-1 and the command 12-1 is abandoned. On the other hand, the status 13-1 is reported to the host processor 1 by a common status queue 4 and a dummy command 16 is loaded into the common command queue 3.
