Title:
iSCSI target returns "Device type is not supported by server",
discovery fails.
Status in “linux” package in Ubuntu:
Incomplete
Status in “open-iscsi” package in Ubuntu:
Incomplete
Bug description:
Connecting from an Ubuntu 12.04LTS server to a
SANRAD (http://www.sanrad.com) switch offering iSCSI connectivity, fails.
First, look for targets
root@media2:~# iscsiadm -m discovery -t st -p 172.31.1.15
172.31.1.15:3260,65535 bigmedia1
172.31.1.14:3260,65535 bigmedia1
172.31.1.16:3260,65535 bigmedia1
172.31.1.15:3260,65535 media1target
172.31.1.14:3260,65535 media1target
172.31.1.16:3260,65535 media1target
172.31.1.15:3260,65535 bigmedia2
172.31.1.14:3260,65535 bigmedia2
172.31.1.16:3260,65535 bigmedia2
Lots of nice targets - now connect to one
root@media2:~# iscsiadm -m node -T bigmedia1 -p 172.31.1.15 -l
Logging in to [iface: default, target: bigmedia1, portal: 172.31.1.15,3260]
Login to [iface: default, target: bigmedia1, portal: 172.31.1.15,3260]: successful
root@media2:~# echo $?
0
Apparently connected - it says successful, and returns zero. Now,
check partitions
root@media2:~# cat /proc/partitions
major minor #blocks name
11 0 1048575 sr0
8 0 731445248 sda
8 1 1048576 sda1
8 2 730395648 sda2
252 0 20971520 dm-0
252 1 8388608 dm-1
Nothing new - sda is my root drive, the new one should be in there as
sdb. Checking dmesg, it has two new lines
[ 358.391438] scsi6 : iSCSI Initiator over TCP/IP
[ 358.645490] scsi scan: INQUIRY result too short (5), using 36
Please see http://karlsbakk.net/tmp/iscsi-debug.txt for a login
attempt with -d 200 and http://karlsbakk.net/tmp/iscsi-fail.pcap for a
traffic dump between the two machines during login attempt.
Please note that with open-iscsi on a CentOS 5.8 machine of the same
make, this works perfectly.
