- REPORT LUNS
- Posted by muriwai on May 9th, 2008
Hi,
I wonder what the format of SCSIOP_REPORT_LUN's LUN_LIST.Lun field is.
Storport.h has
UCHAR Lun[0][8]; // 4 level of addressing. 2 bytes each.
The SCSI standard says nothing about the format. It looks like it's just a
list of 64-bit numbers being LU numbers. Why does storport.h mention "4
level of addressing. 2 bytes each" then?
Thanks,
Andrew

Look at the SAM-4 spec from t he T-10 committiee. LUNs are no longer 8 bits
in length but do indeed have multiple layers of addressing.

Look at SCSI specs at www.t10.org, I think REPORT LUNS is described in SPC or
SAM family of specs.
If the miniport/controller/LUN does not support REPORT LUNS, then SCSIPORT will
enumerate all LUNs from 0 up and stop on first non-responding LUN.
Don't know on STORPORT, probably it uses the same way.

SAM-4 seems to be what I need.
Thank you
