Table 1-6
Head of Queue Tag
The Head of Queue Tag message specifies that the I/O process be placed
first in the logical unit's command queue. When the drive receives a
subsequent I/O process received with a Head of Queue Tag message, the
I/O process that has been already done is not interrupted.
Table 1-7
Ordered Queue Tag
The Ordered Queue Tag message specifies that the I/O process be placed
in the logical unit's command queue for execution in the order received.
All queued I/O processes for the logical unit received prior to this I/O
process are executed before this I/O process is executed. All queued I/O
processes received after this I/O process are executed after this I/O
process, except for I/O processes received with a Head of Queue Tag
message.
