I create four associations as below
# nvme list-subsys
nnvme-subsys0 - NQN=nqn.1988-11.com.dell:powerstore:00:227c6d20994a5764BF97
\
+- nvme0 tcp traddr=172.16.100.161 trsvcid=4420 live
+- nvme1 tcp traddr=172.16.100.162 trsvcid=4420 live
+- nvme2 tcp traddr=fd31:d09b:724c:200:0000:ffff:ac10:c8a1 trsvcid=4420 live
+- nvme3 tcp traddr=fd31:d09b:724c:200:0000:ffff:ac10:c8a2 trsvcid=4420 live
however, if i check individual namespace, there only have three.
# nvme list-subsys /dev/nvme0n1
nvme-subsys0 - NQN=nqn.1988-11.com.dell:powerstore:00:227c6d20994a5764BF97
\
+- nvme0 tcp traddr=172.16.100.161 trsvcid=4420 live optimized
+- nvme1 tcp traddr=172.16.100.162 trsvcid=4420 live non-optimized
+- nvme3 tcp traddr=fd31:d09b:724c:200:0000:ffff:ac10:c8a2 trsvcid=4420 live non-optimized
# nvme list-subsys /dev/nvme0n2
nvme-subsys0 - NQN=nqn.1988-11.com.dell:powerstore:00:227c6d20994a5764BF97
\
+- nvme0 tcp traddr=172.16.100.161 trsvcid=4420 live non-optimized
+- nvme1 tcp traddr=172.16.100.162 trsvcid=4420 live optimized
+- nvme3 tcp traddr=fd31:d09b:724c:200:0000:ffff:ac10:c8a2 trsvcid=4420 live optimized
also it affect iostate output
# iostat 4 ALL | egrep 'n2 '
nvme0c0n2 0.02 0.32 0.00 0.00 1108 0 0
nvme0c1n2 0.00 0.04 0.00 0.00 128 0 0
