Try a 'lsscsi -g' and then a "sg_inq -v /dev/sg??' where ?? is the sg path returned from 'lsscsi -g' And sg_inq -p 80 /dev/sg?? sg_inq -p 83 /dev/sg?? Some of the parameters are used inq params 80, 83 etc I need to refer back to the code to identify exactly where each param is used. (A follow up email tomorrow). Note: lsscsi & sg3_utils available from www.torque.net/sg/ Cheers Mark Albert Pauw wrote: > I noticed something inconsistent (or so it seems). > > If I define something like this: > > tgtadm --lld iscsi --mode logicalunit --op update --tid 2 --lun 1 > --params > vendor_id=MITSUMI,product_id=FD001,product_rev=0001,removable=1,sense_format=0 > > tgtadm --lld iscsi --mode logicalunit --op update --tid 2 --lun 1 > --name scsi_id --value "CDROM ISO" > tgtadm --lld iscsi --mode logicalunit --op update --tid 2 --lun 1 > --name scsi_sn --value "001" > > and log into that target (using open-iscsi) I get in my dmesg: > > scsi2 : iSCSI Initiator over TCP/IP > scsi 2:0:0:0: RAID IET Controller 0001 PQ: 0 > ANSI: 5 > scsi 2:0:0:0: Attached scsi generic sg2 type 12 > scsi 2:0:0:1: CD-ROM MITSUMI FD001 0001 PQ: 0 > ANSI: 5 > sr1: scsi-1 drive > sr 2:0:0:1: Attached scsi CD-ROM sr1 > sr 2:0:0:1: Attached scsi generic sg3 type 5 > > However, if I use the command: > > tgtadm --lld iscsi --op show --mode target > > it shows up as (part of it at least): > > LUN: 1 > Type: cd/dvd > SCSI ID: CDROM ISO > SCSI SN: 001 > Size: 628M > Online: Yes > Poweron/Reset: No > Removable media: Yes > > so the scsi_id and scsi_sn are not used on the initiator and never > turn up, it's the vendor_id and product_id that show up. > > Can somebody shed some light on this (seemingly) inconsistent behaviour? > > Thanks, > > Albert > > > > > > > ------------------------------------------------------------------------ > > _______________________________________________ > Stgt-devel mailing list > Stgt-devel at lists.berlios.de > https://lists.berlios.de/mailman/listinfo/stgt-devel > |
