Bonjour, I'm not sure why it's saying (multiple). But you notice it does that on each separate login session. Possibly Mike Christie will chime in with an answer. It isn't anything I would worry about.
Run this to see the existing sessions. #iscsiadm -m session e.g. My environment is using MPIO and IPv4/IPv6 at same time. You should just see one entry per EQL volume. tcp: [1] [2001:db8:00:00:10:126:204:10]:3260,1 iqn.2001-05.com.equallogic:4-52aed6-a813e0689-e2f004a89e651b0e-linux-iscsi-test-vol0 (non-flash) tcp: [10] [2001:db8:00:00:10:126:204:10]:3260,1 iqn.2001-05.com.equallogic:4-52aed6-a813e0689-e2f004a89e651b0e-linux-iscsi-test-vol0 (non-flash) tcp: [2] 10.126.204.10:3260,1 iqn.2001-05.com.equallogic:4-52aed6-a813e0689-e2f004a89e651b0e-linux-iscsi-test-vol0 (non-flash) tcp: [3] 10.126.204.10:3260,1 iqn.2001-05.com.equallogic:4-52aed6-a813e0689-e2f004a89e651b0e-linux-iscsi-test-vol0 (non-flash) tcp: [4] 10.126.204.10:3260,1 iqn.2001-05.com.equallogic:0-1cb196-c2c0def3d-7a613a8fd9d53da8-ois-chaptest-vol (non-flash) tcp: [5] 10.126.204.10:3260,1 iqn.2001-05.com.equallogic:0-1cb196-c2c0def3d-7a613a8fd9d53da8-ois-chaptest-vol (non-flash) tcp: [6] 10.126.205.110:3260,1 iqn.2001-05.com.equallogic:0-af1ff6-03b521dd7-b550051e2d854404-rhelv6-mpio-test-dw-vol (non-flash) tcp: [7] 10.126.205.110:3260,1 iqn.2001-05.com.equallogic:0-af1ff6-03b521dd7-b550051e2d854404-rhelv6-mpio-test-dw-vol (non-flash) tcp: [8] 10.126.202.240:3260,1 iqn.2001-05.com.equallogic:4-52aed6-08a90c064-074004f1fb153daa-ois-chaptest-vol-dw (non-flash) tcp: [9] 10.126.202.240:3260,1 iqn.2001-05.com.equallogic:4-52aed6-08a90c064-074004f1fb153daa-ois-chaptest-vol-dw (non-flash) And for more detail: #iscsiadm -m session -P 1 Out of curiosity, why don't you want to use MPIO, possibly getting better performance and get redundancy as well?
