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 Time-Out Value Unit. The field specifies the unit of measure as

 

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 time-out functions.

 

F0h

240 x 0.1s units = 24 seconds
