The decision regarding allocation of Task Tags is outside the
scope of the SCSI standards.
Practically speaking, where Tasks Tags are allocated depends
on the implementation.
I have written device drivers that allocated their own Task Tags
(admittedly for 1993 vintage hardware).
I am aware of HBAs that allocate the Tasks Tags themselves, which
removes the duty from the province of any device driver.
Please consult the applicable Product Specification(s) to determine
how Task Tags are handled.
All the best,
