SCSI Description

 

 

 

 

 

 

 

 

 

 

Rotational Position Locking is used for spindle synchronization in

 

 

storage arrays. The modes are:

 

 

 

00b – Disabled

 

 

 

10b – Master

 

RPL

00b

01b – Slave

 

 

 

11b – Not supported

 

 

 

RPL can be overridden if the Maxtor (Vendor) Special Function

 

 

Control page Auto field value = 1.

 

 

 

 

 

 

Rotational Offset indicates the amount of rotational offset that

 

 

the drive uses when synchronized. The rotational offset is applied

 

 

in the retarded direction (lagging the synchronized spindle mas-

 

 

ter). The value in the field is determined by the following formula:

 

 

Offset = 0 … 255

For example, a numerator of 128 indicates an offset of 1/2 revo-

 

 

lution (180°).

 

 

 

The valid parameter values are 0 to 255.

 

 

The specified value may be rounded. Rotational offset is not used

 

 

when the drive is configured as the synchronized-spindle master.
