DTOLI (Disable Target Originated Loop Initialization) bit of one specifies the Target does not generate the initializ-
ing LIP following insertion into the loop. The Target will respond to an initializing LIP, if received. The Target will
generate the loop failure LIP if it detects a loop failure at its input and the initializing LIP when the loop failure is cor-
rected. When DTOLI is zero, the Target generates the initializing LIP after it enables a port into a loop.

RR_TOV Units field indicates the units in which the RR_TOV is calculated, according to Table 158.
Table 158: Values for RR_TOV Units
•
RR_TOV (Resource Recovery Time Out Value) field indicates the number of time units specified by the RR_TOV
UNITS field that shall be used by the timer that performs the RR_TOV timeout functions. The timer accuracy is +/-
0.1 seconds. Changes to RR_TOV will only affect the usage of the timer for non-authentication situations.
0.1 seconds. Changes to RR_TOV will only affect the usage of the timer for non-authentication situations.
When the RR_TOV Units are set to no timer, the RR_TOV value (byte 7) shall be ignored by the Target and a default
timeout value of 2.0 seconds shall be used for RR_TOV.
timeout value of 2.0 seconds shall be used for RR_TOV.
When the RR_TOV Units are set to 0.1 seconds the following rules apply:
- a value of 00h will result in an infinite timeout value (no timeout will occur) Note: This will also cause E_D_TOV
- a value of 00h will result in an infinite timeout value (no timeout will occur) Note: This will also cause E_D_TOV
to have an infinite timeout value.
- a value from 01h to 7Eh will result in a timeout duration that is the product of the RR_TOV value and 0.1 seconds
any value from 7Fh to FFh will result in the Target terminating the command with CHECK CONDITION status.
any value from 7Fh to FFh will result in the Target terminating the command with CHECK CONDITION status.
The sense key is set to Illegal Request and the additional sense code is set to INVALID FIELD in the PARAME-

TER LIST.
When the RR_TOV Units are set to 10 seconds, the following rules apply:
- a value of 00h will result in an infinite timeout value (no timeout will occur) Note: This will also cause E_D_TOV
to have an infinite timeout value.
- a value of 01h will result in a timeout duration that is the product of the RR_TOV value and 10 seconds
- any value from 02h to FFh will result in the Target terminating the command with CHECK CONDITION status.
- The Sense Key is set to Illegal Request and the Additional Sense Code is set to INVALID FIELD in the PARAM-
