iscsiadm do not allow to discovery the same LUN with second NIC
Issue
-
iscsiadmdo not allow to discovery the same LUN with a second NIC when usingmultipath, as described in the tentative bellow:# iscsiadm --mode iface --op=new --interface iscsi-0 # iscsiadm --mode iface --op=new --interface iscsi-1 # iscsiadm --mode iface --op=update --interface iscsi-0 --name=iface.net_ifacename --value=eth0 # iscsiadm --mode iface --op=update --interface iscsi-1 --name=iface.net_ifacename --value=eth1- Discovery using first NIC works properly:
# iscsiadm -m discovery -t st -p 172.17.50.10 -I iscsi-0 172.17.50.10:3260,1 iqn.2012-08.com.example:test:10000:test5- But when try with the second NIC, the following error appears:
# iscsiadm -m discovery -t st -p 172.17.50.10 -I iscsi-1 iscsiadm: cannot make connection to 172.17.50.10: Connection timed out iscsiadm: cannot make connection to 172.17.50.10: Connection timed out iscsiadm: cannot make connection to 172.17.50.10: Connection timed out iscsiadm: cannot make connection to 172.17.50.10: Connection timed out iscsiadm: cannot make connection to 172.17.50.10: Connection timed out iscsiadm: cannot make connection to 172.17.50.10: Connection timed out iscsiadm: connection login retries (reopen_max) 5 exceeded iscsiadm: No portals found -
The same behavior occurs if I change the interface order (tried interface iscsi-1 first and iscsi-0 second), the first discovery happens successfully and the second shows the same problem. How to fix it?
