Thread-topic: Separate unit directories for each logical unit?
Well, in playing around with things, it seems that both Windows and Mac
OS X are happy with having multiple LUNs in the one unit directory.

Subject: Separate unit directories for each logical unit?
Hi,
In looking at the SBP Spec, V3, it says:
"Targets shall implement at least one logical unit: logical unit zero.
Additional logical units may be implemented. A logical unit is
described by entries in the unit directory or by entries in a logical
unit
directory dependent upon the unit directory or by entries taken in
combination from both places. The properties of logical units are
established by Command_Set_Spec_ID, Command_Set, Command_Set_Revision
and
Fast_Start entries; an instance of a specific logical unit is
established by a Logical_Unit_Number entry.
7.7 Logical unit directory
The logical unit directory provides one of two methods by which a
logical unit implemented by the target may be described (the other is a
Logical_Unit_Number entry in the unit directory, described in 7.8.15)."
Do we need a separate Unit Directory for each Logical Unit? Could be get
away with one Unit Directory with multiple Logical Unit Number Entries?
On the other hand, for greatest portability or conformance, do we need
Logical Unit Directories?
