RHA | Require Hard Address. If the drive is not attached to an arbitrated loop, the RHA bit is | |
| ignored. | |
| 0 The drive follows the normal initialization procedure, including the possibility of | |
| obtaining a soft address during the loop initialization process. | |
| 1 When attached to an arbitrated loop, the drive will only attempt to obtain its hard | |
| address (available via the device address jumpers) during loop initialization. The | |
| drive will not attempt to obtain an address during the LISA phase of initialization. | |
| If there is a conflict for the hard address selection during loop initialization or it | |
| does not have a valid hard address available, the drive will enter the non- | |
| participating state. If the drive detects loop initialization while in the non- | |
| participating state, it will again attempt to get its hard address. If the hard address | |
| has not changed from the address obtained in a previous successful loop | |
| initialization, the drive will attempt to obtain the address in the LIFA phase if a | |
| valid Fabric Login exists or in the LIPA phase of loop initialization. If the hard | |
| address has changed, the target will attempt to obtain the new address in the | |
| LIHA phase. | |
|
| |
ALWLI | Allow Login Without Loop Initialization | |
| 0 The drive is required to verify its address through the loop initialization process | |
| before a login is accepted. | |
| 1 The drive uses the hard address available in the SCA connector or device address | |
| jumpers and accepts logins without verifying the address with loop initialization. | |
|
| |
DTIPE | Disable Target Initiated Port Enable | |
| 0 The drive enables its port into the loop without waiting for a Loop Port Enable | |
| primitive. | |
| 1 The drive waits for an initiator to send the Loop Port Enable primitive before | |
| inserting itself into the loop. The drive uses the hard address available in the SCA | |
| connector or device address jumpers to determine if primitives are addressed to it. | |
| A Loop Port Enable primitive with the broadcast address will also cause the drive | |
| to insert itself into the loop. | |
| NOTE: If the DTIPE bit is set to 1, the PLPB bit must be set to 0. | |
|
| |
DTOLI | Disable Target Originated Loop Initialization | |
| 0 The drive generates the Initializing LIP after it enables a port into a loop. | |
| 1 The drive does not generate the Initializing LIP following insertion into a loop. It | |
| will respond to an Initializing LIP when it is received. It will generate the Loop | |
| Failure LIP at its input and the Initializing LIP when the loop failure is corrected. | |

RR_TOV Units | Resource Recovery | |
| follows: |
|
| 000b | No timer specified |
| 001b | 0.001s |
| 011b | 0.1s, units used by HP Ultrium drives |
| 101b | 10s |
|
| |
RR_TOV | The number of time units specified by the RR_TOV Units field that are used by the timer | |
| that performs the RR_TOV | |
| F0h | 240 x 0.1s units = 24 seconds |
