I have installed the scsi-target-utils package on CentOS and I used it to perform a discovery. The discovery did give me an active session. I restarted the iscsi service but I do not see any new devices (fdisk -l). I see in /var/log/messages that my connection is operational now.

I'm not sure how to debug this further. Can someone direct me into fixing this?

discovery:

iscsiadm -m discovery -t sendtargets -p 192.168.0.155

returns:

192.168.0.155:3260,-1 iqn.2009-02.com.twinstrata:cloudarray:sn-1d07c1b62d4ec8f3

Just to verify it actually worked:

iscsiadm -m session

returns

tcp: [1] 192.168.0.155:3260,1 iqn.2009-02.com.twinstrata:cloudarray:sn-1d07c1b62d4ec8f3

restarting as the directions say to do:

service iscsi restart

output written to /var/log/message

Ran a login command:

iscsiadm -m node -T iqn.2009-02.com.twinstrata:cloudarray:sn-1d07c1b62d4ec8f3 -p 192.168.0.155 -l

No errors, no logging occurred.

Next I compared the output from "fdisk -l|egrep dev" both with the iscsi session and without. There is no difference. I suppose I could just look in /etc/mtab. Any ideas on how I can get an iscsi device?
