Hello.

I did setup an iSCSI target on a Dell Storage system. I configured /etc/iscsi/iscsi.conf with CHAP. I can see

# iscsiadm -m session -o show
tcp: [1] 172.16.52.202:3260,3 iqn.1988-11.com.dell:01.array.bc305b5e96aa (non-flash)
tcp: [2] 172.16.52.204:3260,4 iqn.1988-11.com.dell:01.array.bc305b5e96aa (non-flash)

But I can not see the device when I use lsblk. How do I add sdc?

Any help is appreciated!

Thank you.

Click to expand...
The "enclosu" portion signifies that these are top level Enclosure connections. So you have 4 paths to your SPs, ie 4 SCSI adapters with good connections. However, the fact that no LUNs are listed under "enclosu" means that there is none. Its very likely that you did not fully assigned the LUN to a portal group or whatever your vendor calls it (to iSCSI target).
You could run iscsiadm -m session -P 3 to get more information. I would also go over the vendor documentation again to make sure that you followed all the steps.

Good luck
