cannot connect to SAN

Hello I canno connect to the SAN, no ACL is setup, I have other 4 hypervisors connected to the SAN without problems:

[root@hypervisor7 ~]# telnet 10.62.24.40 3260
Trying 10.62.24.40...
telnet: connect to address 10.62.24.40: Connection refused
telnet: Unable to connect to remote host: Connection refused
[root@hypervisor7 ~]# iscsiadm -m discovery -t sendtargets -p 10.62.24.40
iscsiadm: cannot make connection to 10.62.24.40: Connection refused
iscsiadm: cannot make connection to 10.62.24.40: Connection refused
iscsiadm: cannot make connection to 10.62.24.40: Connection refused
iscsiadm: cannot make connection to 10.62.24.40: Connection refused
iscsiadm: cannot make connection to 10.62.24.40: Connection refused
iscsiadm: cannot make connection to 10.62.24.40: Connection refused
iscsiadm: connection login retries (reopen_max) 5 exceeded
iscsiadm: Could not perform SendTargets discovery: encountered connection failure

We have one license but not in this SAN, we are doing some tests. Is trial license limited in someway that explains this?

the trial has no limits on connections.

check your routing to the storage IP.

Sorry, I forgot to mention I can ping the SAN:

[root@hypervisor7 ~]# ping 10.62.24.40

I also checked SAN logs and the only thing I can find about ip I try to connect from is I can see ip in arp -nv output. No other log show anything about this ip. Even tried to add to de ACL, without success.

is this a virtual IP assignment? If so, make sure failover service is running.

Any bonds, vlans ?

Hello, no bonds, vlan yes, but access mode, same config than the other Hypervisors and switch ports that are currently running ok.

Something is blocking the connection. Can you try it without the VLAN?
