You do not need to do this.

Something from "iscsid" indicating a login error value? For that target is the chap info what you wrote above? Do iscsiadm -m node -T iqn.2000-01.com.synology:rackstation.name -p 192.168.214.199 to see. > iscsiadm: Could not log into all portals > [ OK ] > > dmesg output: > Loading iSCSI transport class v2.0-871. > cxgb3i: tag itt 0x1fff, 13 bits, age 0xf, 4 bits. > iscsi: registered transport (cxgb3i) > Broadcom NetXtreme II CNIC Driver cnic v2.0.1 (Oct 01, 2009) > Broadcom NetXtreme II iSCSI Driver bnx2i v2.0.1e (June 22, 2009) > iscsi: registered transport (bnx2i) > iscsi: registered transport (tcp) > iscsi: registered transport (iser) > scsi20 : iSCSI Initiator over TCP/IP > BUG: warning at drivers/scsi/libiscsi2.c:465/iscsi_complete_task() > (Tainted: G ) When you did the restart, were there sessions already running? Were you also running IO to those sessions? This trace is bad because it indicates a double free. I am not sure if it is related to the login error above though.
