Table 5-1:
The command can be accepted, but it can not be executed
because the Drive is busy.
Three different BUSY situations may occur:
1) The drive is already executing a command from another
initiator and the new command can't be executed in
parallel.
2) The Drive is executing an Immediate-type command
(from any initiator) and the BSYI-option is turned on
(please refer to the BSYI-bit in the Miscellaneous
Parameters Page of the MODE SELECT command). This
condition will prevail until the Immediate-type
command has completed its execution (or the BSYI-
option is turned off).
3) The drive is occupied by a drive-initiated
preparation activity (as e.g. Autoload) and the BSYA-
option is turned on (please refer to the BSYA-bit in
the Miscellaneous Parameters Page of the MODE SELECT
command). This condition will prevail until the
drive-initiated activity has completed (or the BSYA-
option is turned off).
An abnormal condition has occurred. The Initiator should
issue a REQUEST
information.
The requested operation (the last command) was completed
successfully.
This status is
command in a series of linked commands.
The status is sent to an Initiator that attempts to
access the Drive
Initiator.
