On shutdown iscsi reports "iscsiadm: No matching sessions found" and iscsid issues a warning "Not stopping iscsid : iscsi sessions still active" in RHEL 6

Issue

• When stopping all services on shutdown there is a warning :

"Not stopping iscsid : iscsi sessions still active"

• shutdown hangs or delays when iscsid reports sessions are still active
• If attempting to manually log out of all iSCSI sessions using the --logoutall=all or -U all it does not find any matching sessions:

# iscsiadm -m session
tcp: [1] 192.168.2.19:3260,2001 iqn.1992-08.com.example:sn.1573969083
# iscsiadm -m node --logoutall=all

iscsiadm: No matching sessions found

If using --logout or -u instead it logs out successfully:

# iscsiadm -m node -u
Logging out of session [sid: 1, target: iqn.1992-08.com.example:sn.1573969083, portal: 192.168.2.19,3260]
Logout of [sid: 1, target: iqn.1992-08.com.example:sn.1573969083, portal: 192.168.2.19,3260] successful.
