Couple of comments. 1. In section 1.1.5.2, the changes for version 1.1, it seems like the version 1.0 has also changed by not supporting VD_OP_SCSICMD. It used to be part of version 1.0 but now has moved to version 1.1 only. This means the existing interface is also changing. Further I am assuming that this change is OK since VD_OP_SCSICMD is not currently used by anyone, right? 2. In section 1.1.5.13, the TPRIO is 8-bit field but later in the description it is referred to as 4-bit field. Does that mean only lower 4-bits are meaningful? If this is 4-bit field then other 4-bit should be marked as unused or reserved. -- Hitendra Zhangada ============================================= SPS Common SW Features Engineering Software Group, Sun Microsystems, Inc.

The brief description of the changes are:

 - update to vDisk SCSI command (section 1.1.5.13)

Couple of comments.

1.  In section 1.1.5.2, the changes for version 1.1, it seems like
     the version 1.0 has also changed by not supporting VD_OP_SCSICMD.
     It used to be part of version 1.0 but now has moved to version 1.1
     only.  This means the existing interface is also changing.  Further
     I am assuming that this change is OK since VD_OP_SCSICMD
     is not currently used by anyone, right?

2.  In section 1.1.5.13, the TPRIO is 8-bit field but later in the description
     it is referred to as 4-bit field.  Does that mean only lower 4-bits are
     meaningful?  If this is 4-bit field then other 4-bit should be marked
     as unused or reserved.

Yes, we are moving the support of VD_OP_SCSICMD from 1.0 to 1.1. This operation was never described in 1.0 so it was unusable, and nobody is using it. > 2.

If this is 4-bit field then other 4-bit should be marked > as unused or reserved. The description mentions that only 4-bit are meaningful to match with the current interpretation of a task priority from the SCSI Architecture Model (SAM-3). As the task priority is number, I think it is better for the representation and implementation to reserve an entire byte (even with a limited range) instead of a bit field. Rgds, alex.
