Hi List
I'm really interested in getting some basic VTL functionality up and
running, it was a great surprise to see this is being built into stgt.
So far, using 1.0.15 I have used the example VTL configuration file to
create a robot and 3 drives which are visible to my host:
scsi1 : iSCSI Initiator over TCP/IP
Vendor: IET Model: Controller Rev: 0001
Type: RAID ANSI SCSI revision: 05

st1: Block limits 4 - 1048576 bytes.

st2: Block limits 4 - 1048576 bytes.
mtx looks OK:
[root@linux-media ~]# mtx -f /dev/changer-sg5 status
Storage Changer /dev/changer-sg5:3 Drives, 236 Slots ( 20 Import/Export )
Data Transfer Element 0:Empty
Data Transfer Element 1:Empty
Data Transfer Element 2:Empty
Storage Element 1:Full :VolumeTag=LTO901L3
Storage Element 2:Full :VolumeTag=LTO902L3
Storage Element 3:Full :VolumeTag=LTO903L3
Storage Element 4:Empty:VolumeTag=
Storage Element 5:Empty:VolumeTag=
Storage Element 6:Empty:VolumeTag=
.
.
.
Trouble is when I try and load a tape to a drive:
[root@linux-media ~]# mtx -f /dev/changer-sg5 load 2
mtx: Request Sense: Long Report=yes
mtx: Request Sense: Valid Residual=no
mtx: Request Sense: Error Code=70 (Current)
mtx: Request Sense: Sense Key=Hardware Error
mtx: Request Sense: FileMark=no
mtx: Request Sense: EOM=no
mtx: Request Sense: ILI=no
mtx: Request Sense: Additional Sense Code = 15
mtx: Request Sense: Additional Sense Qualifier = 01
mtx: Request Sense: BPV=no
mtx: Request Sense: Error in CDB=no
mtx: Request Sense: SKSV=no
MOVE MEDIUM from Element Address 1001 to 500 Failed
This is how I created the tapes:
cd /root/tapes/
tgtimg --op=new --device-type=tape --barcode="" --size=1 --type=clean
--file=notape
tgtimg --op=new --device-type=tape --barcode="LTO901L3" --size=1024
--type=data --file=LTO901L3
tgtimg --op=new --device-type=tape --barcode="LTO902L3" --size=1024
--type=data --file=LTO902L3
tgtimg --op=new --device-type=tape --barcode="LTO903L3" --size=1024
--type=data --file=LTO903L3
How I added them:
tgtadm --lld iscsi --mode logicalunit --op update --tid 5 --lun 4
--params element_type=2,address=1000,barcode=LTO901L3,sides=1
tgtadm --lld iscsi --mode logicalunit --op update --tid 5 --lun 4
--params element_type=2,address=1001,barcode=LTO902L3,sides=1
tgtadm --lld iscsi --mode logicalunit --op update --tid 5 --lun 4
--params element_type=2,address=1002,barcode=LTO903L3,sides=1

Can anyone see if I am missing a step here?
