Analysis of the termination status

BUSY/QUEUE FULL status

This status indicates that the IDD is currently executing processing of another command and that a
new command cannot be received. The INIT that receives this status can reissue the original
command.

Under a multi-initiator environment, when an INIT receives this status, the time until the IDD can
receive the next command depends on the operating state with other INITs, so ordinarily, it cannot
be predicted. In such a case, it is necessary for the INIT that issued the command for which this
status was received to repeatedly issue the command until it is accepted.
