17.3.14 Third Party Process Logout (TPRLO)
The TPRLO request is used to invalidate the operating environments between the specified image(s) at the recipient N_Port
(i.e., the drive). These image pairs being invalidated are assumed to have been previously established with a Process Login
(PRLI). The originator establishing the process image (with the PRLI ELS) can itself terminate the image with a Process Log-
out (i.e. PRLO) ELS. An originator can terminate the process pair established between another third party originator and the
recipient (i.e. the drive) using TPRLO. TPRLO has the same effect as if the third party originator performed PRLO. Upon exe-
cution of a valid TPRLO ELS, the drive will set all tasks, reservations, mode page parameters, and status for the specified
image pairs to the state they would have after a SCSI device reset or power-on reset.
