Re: iSCSI MIB Object Model

Folks,

Just to fill in a couple of things:
1) There is a move afoot in T10 to add some functions related to these LU
inventory topics.  There is a move to work on a bridge controller command
set (George Penokie (Tivoli) and Robert Elliot (Compaq)). Such a command
set would have ways of asking the bridge controller "what it is bridging".
Additional George Penokie is pushing a set of proposals for getting other
device level configuration information from a target (stuff like Logical
unit inventory).

2) If your SCSI Target supports the Access Controls (approved for inclusion
in SPC-3), there is a service action called "REPORT LU DESCRIPTORS" which
essentially is a mechanism to get an inventory of all the logical units in
the target device (technically as managed by the access controlls
coordinator in the device).  This is as a management type command, and is
not subject to LUN Mapping constraints.   This inventory information
includes "default LUN value", VPD page83 LU WWUnique identifier, "Device
Identifer" (as set by command) and, for disks the read capacity
information.
